How much Power supply is needed here?

Question: How much Power supply is needed here?

Hi guys, new here...I'm setting up a new pc, sooo a few questions here.
I'm planning on getting an Asus A88XM-plus motheboard, Amd X4 860K cpu and Sapphire R9 280 3GB video how much power supply would be enough...450-500W?..would 650 be an overkill? Is all of this fully compatible?
Do I need a sound card, modem or special cooling or something? ( I already have 2*8gb Ram sticks and HDD, don't really need DVD drive).
I'm also thinking in between Antec 902 V3 case and a lot cheaper LC Power Gaming 975b Air wing much quality difference is there in between these two?
Also, how much improvement is there in between this card and my current one, sapphire r7 265 2gb?
Are there anything that you would exchange for something else...I'm on a tight budget, but I don't mind spending a few extra bucks if it be worth in the long run.
Thanks in advance.

I have a Gigabyte Z77X-D3H Rev 1.0 motherboard and am looking to add an EVGA GeForce GTX 960 GPU, but my current PSU does not have the required PCI-E connection. I am looking for a 750W PSU that would be compatible with both, Preferably modular in design.

I have 2 DVD drives and 5 case fans also, any suggestions. Thank You.

Hi there. I have a HP Pavillion with a psu of 300watts. I have just purchased an Nvidia GeForce 7600GT to replace my current 7300LE. The only reason is that im a player of The Sims 2 and have 6 expansions plus the original base game. I have been having crashing issues since day one due to my video card being so bad. Hopefully my new card will solve my problem but i need to upgrade my psu to at least 450watts. I really need some help with this...i know how to install a new graphics card and have done it before but i have no idea about psu's and all the numbers that surround them!

Answer:New Power Supply Needed!

Psu are not that hard to fit. Just make sure that as you disconnect the cables that you make a note of where they go, that way when it comes to putting them back, you know where to put them. 450watt psu will be fine. But pay a little more and get a good one.

I need to know if my power supply ought to be replaced or not. I replaced my old one a couple of months ago, but due to finacial reasons I had to go the cheap route.

I bought this unit:

a MGE Vigor 400 watt power supply.

I have a P4 3.0, 2 HDs, 2 512mb chips of ram, and a BFG OC'd fx 5500 video card, and 1 fan. My computer has ran great, but recently I added the second HD, and occasionally I will turn on my computer and nothing will boot up, no image, no loading of the OS. I'm wondering if this is being caused by the PS being overworked.

Here is the voltage read outs right now, read by a program called PCAlert 4:

Vcore 1.50 - 1.54
3.3V: 3.26
+5V: 5.08
+12V: 11.64 - .70

Do these look alright?

If not, please recommend some good cheap Power Supplys, preferably no more than $50. Thanks

I found a picture of the motherboard and the atx connector is a 24 pin connector. Just find any good brand psu with a 24 pin power supply.

I bought a 550w antec true power supply, its a 24 pin connector. Even though I dont have a 24 pin motherboard, this is the way that all new motherboards are going. To anyone buying a new psu, get a 24 pin one and an adapter if you have a 20 pin mobo.

I havent heard of it being called atx2, but the 24 pin psu should be what it needs.

can someone help me out i currently have a 250w PS but i am building a new pc and i would like to know how to determine how much supply is needed.

Answer:how to determine how much power supply is needed?

It really depends on what devices you are going to be using. If you are using a couple hard drives, a CD-RW and/or a DVD-ROM/RW or whatever then you need to allow some power comfort. Also consider any devices that you will be connecting via FireWire or USB.
It wont hurt to "over do it". In most cases, you'll be fine with a power supply that puts out 400W or better.
I have a 420W in one of mine and have a bunch of external devices, 2 swap drives, a DVD, CD-RW, a lot of color-lit fans and a couple of UV tubes. I've never had a problem with power either.

In most cases, it's not the wattage amount, but the quality of the PSU itself. Make sure to buy a respected brand.

I recently built my first computer. Pretty much everything is working fine, just needs a few tweaks. One thing that I noticed is that there is an Aux Power Supply cord and there seems to be a connector on the motherboard. The motherboard is a Gigabyte GA-8IHXP. Only, I couldn't seem to connect them together. Do I need to hook up this addtional power cord to the motherboard, or can I just leave it alone?

My Processor is a Pentium IV 2.8 GHz Socket 478.
EDIT: I accidentally put ATX 12V in the thread title, but was reading the wrong thing. Sorry about that.

Hey all, I'm new posting here, but read a few threads and you are the people who can help me =D. I build my own computer a while back and have recently been adding onto it, but lately I am having a problem which I am pretty sure is the power supply. The problem I am experiencing is a random cutting out of all power in my computer, which forces it to reboot. I have made a temporary workaround in unplugging some power using devices, but I know it is time to get an upgrade in the power supply, however I am not really sure what size to get, or if my current size is good, and it is just crapping out on me. Listed below are my system specs, and hopefully you all can help me out.

Current System:
P4 2.4 Ghz
3 Hard drives (One 60 Gig Seagate and two 250 Gig Western Digitals)
512 Ram
DVD+-RW Drive
DVD Rom Drive
Radeon 9200 se Video Card
Creative Audio PCI Sound Card
Generic Motherboard

Currently all of that is running off of a 400W power supply that is a little less than 2 years old. This computer has been in use heavily for the full 2 years.

Once again, any help you all can offer will really be appreciated, and I look forward to your responses.

Power supply's are easy enough to test. If you don't have a tester take the tower into a shop and have them test it. Cost is minimal. Bad capacitors may also be a source of your problem.

I am considering upgrading my motherboard and processor to xp2000 or 2300. Will a 300 watt power supply be adequate for this. Also is it advisable to have an extra fan fitted to the chassisDaviva

Answer:power supply needed for xp2000+ processors

Many empty cases I see for sale, and labelled athlon ready, contain a 300 watt psu. Personally I would upgrade to 450 watt, possibly with variable fan speeds.Maplin have special offers from time to time. Athlons run hotter than pentiums, so cooling is important.Suggest you start with upgrading the psu, and monitor the temperature under intensive use.AMD publish guidelines on cpu temperatures, and if you find you are running near the upper limit, then look at additional cooling.Movement of air inside the case is important, which is why round connecting cables are gaining favour.My own athlon 2200 has 450 watt power supply, a cheap fan on the back (taking up an expansion slot position) and a fan assisted hard drive heat sink.Temperatures under intensive use rarely go above 60 degrees.

Hello.I was thankful when my computer was in sleep mode when there was a two hour power cut today. When power was restored,it took a long time for my computer to start up but thankfully she burst into life and all was eventually well.This bothered me a lot as we're not known for our power cuts. It also made me think about a computer power supply backup should it happen again. Its not a 'knee jerk' reaction but I dread to think of what could've happened had the power gone off in the middle of being 'live'.I've been looking at power supply backups and there's a bewildering array of products. I'm not looking to spend a fortune on one,so would like your recommendations as to what make and model to look for within the Amazon UK website suitable for my computer and screen please.My computer is a Dell Studio desktop with a Dell monitor.

Customer has brought me a Sony Vaio PCV-C11L and an ATX power supply that he wants installed to replace 'blown' PS.

Motherboard is ASUS P4SD-VL and the existing PS has additional power plug (P2 3-pin) that plugs into port immediately adjacent to main power (P1).
While the physical dimensions will offer a problem to installation...... I think that can be overcome. My greatest concern is just what the P2 is for, since the replacement PS doesn't have that plug . Have not been able to locate a 'map' of this motherboard -- Sony doesn't have any info.....

Ok, so my computer is still not up and running (I took the weekend off from troubleshooting). I just tested my case's PW_Switch cable on my current computer and got LEDs and fans spinning. Case cables ruled out.

I still have the mobo as a possible offender, but I just noticed something else...

My power supply's main mobo connector (the 24 pin molex guy) has a single pin missing...would this account for my computer not getting any power at all? I can't recall whether or not the PSU's been like that from the start, so I still have no way of knowing if the computer's not booting because of a DOA mobo or the PSU.

Any ideas?

Answer:Update on my computer - Power Supply Info needed...

The -5 volt on most newer PSU have been removed since it's not really used anymore...that's probably the missing pin that your referring too. Shouldn't be anything to worry about.

I still think it's more of a mobo issue, anyway for you to get your hands on a known working psu just to test on your machine?

I've been reading through multiple threads on similar issues. My video card needs replacing on my XPS 8300, and the one Dell recommended and sent (since returned) would never work. I think that I'm stuck in the no man's land of either using 'legacy' cards (and my first try from Dell, recommended by Dell didn't work), or upgrading the PSU to support the newer cards.So here's what I got for a card: AMD Radeon HD 6870 1GB GDDR5 Graphics card (Dell Y9XH7)
I'm pretty sure I need to update my PCU, which is the standard 460W; I also need the support clip as this is a full-sized card; my other was the factory, small PCI Express card. This card also has two six-pin power supply inputs which my original didn't.Desperately seeking PSU and cords recommendations, and whether the factory motherboard will have any issues with this card.Also, this card is 1 GB, and my small factory card was two - but the newer cards process better/differently, so it isn't a 'downgrade' this correct?My PC stats:

Anyway so I took the hard drive out of the antec built and placed it in one of the enlight/ocz builts and no more problems.

Hey, I joined this forum because I am interested in doing a fair amount of modification to my current computer and I've got some basic questions to ask. I've got a eMachines T2825 PC and am interested in getting a GeForce 6800GT card to replace the one I currently have put in there, a FX 5700le. Doing so would require putting in a new power supply, but I'm interested in going further and buying a new case w/ power supply because for about the same price as a power supply I can get a better ventilated case that also should have a quieter fan (The current T2825 case heats up my upstairs room way to much and keeps those in the bedrooms around it up at night if I do not turn it off, while the other -older- eMachines here makes almost no noise and runs cooler to the touch...) My question is, how difficult would it be to transfer my system to a new case (I've done basic installation of cards and RAM, and know enough to indentify the hardware in there, but I've yet to tackle anything at this level; ) or would it be a smarter move to go for just a new power supply and card?

hi mehilton,
Welcome to Lenovo Community Forums!
You can check your system's Hardware Maintenance Manual and check (page 45)
   this is a Part list and upgrade option. You'll find the Power Supply compatible for your system and its part number.

You can call Lenovo Spareparts (877 4536686 and prompts 4....3....2)    about the part number if you're planning to purchase one.
Technically a Generic ATX PSU will work on your system but the problem is some connectors on a K410 PSU is specially made for it and a feature like the Power mode Ambient light will require a original K410 PSU
see this discussion.

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

I've returned from living in the US and have a Satellite M35X-S149 notebook computer. As it was purchased in the US, it has a power supply that runs off a US two pin plug and the power lead has only a two way lead joining into the battery.

I would like to know if I can purchase a UK power supply for use here in the UK. Just so you know what I've tried already: I found a Toshiba power lead with a 3-pin plug on the end and tried to fit this into the battery pack, but that doesn't work as the battery only has 2 holes for lead to go into and UK leads have 3 connectors not 2 so that didn't work!

I've now realised I need to buy the whole power supply and am not sure which one to get.

Can anyone advise me if this is possible and what to purchase for my model of notebook?


Answer:Switching from a US power supply to a UK supply on Satellite M35X-S149

I think you will need an new European AC adaptor.
I think a AC adaptor for a European series like M30X could be compatible with yours M35X.

The M30X supports this one:
PA3396U - 65W - 19V - 3.42A - 100~240V

You can order it from the Toshiba ASP in UK

I got a new 90W Power Supply for my SL510. But from the PowerManager, as well while in the booting phase, it is recognized as a 65W Supply. ( I get while booting the message to use the shipped supply instead of this weaker one, in the PowerManager i get : "65W AC Adapter is attached") Is there a way to tell my system that the supply is a 90W unit ? Is this new supply maybe already broken ? How does my computer tell which adapter is attached ? I already updated to the latest Bios, but it did not do much.

Answer:90W Power Supply recognized as 65W Supply.

Can you tell us what model (machine type) of SL do you have? The machine type can be found on a sticker on the bottom of the unit.
Also is there a S/N or Part number listed on the A/C Adapter? If so can you let us know what it is?

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A

Answer:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply? A nice feature of the laptop is that you can watch DVDs without powering up the Windows operating system (it has a small linux OS for the DVD player). Granted, the DVD drive and screen are prob...

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!

I have a Dell Dimension E510 that as of yesterday, won't power up anymore. The power light blinks orange and the computer does nothing when the power button is pushed or held in. It's about 16 months old and is out of warranty, so I'm trying to diagnose the problem myself.

I did some searching on the internet and found that this seems to be a common issue on these Dells, sort of a long term infant mortality issue. The most common causes seem to be a bad PSU, MOBO or a shorted USB input.

I've done some diagnostic checks/testing so far and am now stuck. Here's what I know.

- The USB ports don't appear to be shorted. I also disconnected the connector for the USB (which includes the power switch :banghead and it doesn't change any of the results that follow.
- I removed the power supply and jumped Power On (terminal 14, green wire) of the main ATX connector to ground. The fan comes on and all voltages (3.3, 5 and 12v)check out, including around 5.35v at Power Good (terminal 8, gray wire).
- With the power supply back in and everything connected, there is only 3.3mv at Power Good. As I understand it, this would normaly point to a bad power supply; however, all of the voltages check out when the unit is disconnected from everything.

Is is still possible that the power supply is bad, or is it more likely (or definitely) that the MOBO is the culprit.

Any help, including suggestions for additional testing is greatly appreciated.

Ever since i got this new motherboard and CPU ive been having a bit of a nightmare with it.

Gigabyte ga-ma790fx-ds5 -Latest Bios
AMD Phenom Black Edition 9850,
4 gigs PC 6400 ram (Corsair XMS2 CM2X1024-6400
ATI Radeon 4870

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)

It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.

Answer:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

I run a 2004 HP Pavillion XP with an AMD 2.08 & ddr 2700. It has 64mb integrated video & an AGP4X/8X slot; A7V8X-LA, VIA VT8378,  UNIVERSAL 1.5v AGP 3.0 MBO. 1.To convert to a 128 or 256 mb video card, will the cards require an external power attachment, such as from my spare floppy connector? 2. Will the BIOS handle an AGP 6200 card? 3. To update my 250w ATX12V power supply, what happens if the new psu has a manual on-off switch? My current unit has a remote front panel interrupt-type power switch. 4. My mbo handles SATA I. If I use a new PSU with SATA, will SATA II devices have built-in jumpers to convert back to SATA I?  5. The mbo supports a 3200+ processor, will DDR 3200, 400 mhz memory work with the current 2700+ 333 mhz processor; is this called overclocking?

Answer:AGP Video Card Power & ATX12V Power Supply Manual Switches

Okay, hopefully I don't miss anything, that's quite a list 1. Video cards don't connect to the power supply, they draw the power through the mother board.2. The AGP 6200 should work just fine, just remember to disable the integrated video in the bios.3. The switches on the power supplies are just a master on/off, the power button on the front of the computer isconnected to your mother board.  Don't worry about that one.4. Why not pick up a SATA II controller?  Treat yourself 5. No, it's not overclocking, I actually wouldn't recommend overclocking at all.  Whether or not your motherboard will actually work with the DDR 3200 that should be in your motherboard manual, or if you want me to look that up for you post your make and model of motherboard.  A good rule of thumb is to only get the type of RAM that is already installed.  I'm referring to the speed and type, not the size.I hope this helps, if you have any other questions don't hesitate to ask.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place.

Answer:Y580 Blinking power button led and power supply turns off

How many watts is your power brick rated at? I had a similar issue when I used a brick from another laptop. It had the right voltage and the same plug, but it was delivering less power than the original one. When doing basic office stuff it was working fine and charging the battery, but when gaming it would work fine for 2 minutes and then display the same symptoms as your Y580.
Hopefully you ordered the right, more powerful brick. I think the right one is rated at 90W, but I'm not sure.

My Equium A60-692 has stopped receiving any power from the AC adaptor (tho I've metered it and its giving out a good 19v). I've noticed the end of the adaptor (the end that goes into the laptop) is different to normal ones. Rather than having a hole at the center that a spike on the laptop fits into, its just got a flat piece of metal. Just wondered this was normal and the problem is inside the laptop or if the spike has somehow snapped off and is stuck into the adaptor. It looks like its supposed to be this way but it seems a bit weird...


Answer:Equium A60-692 Power supply - laptop doesn't receive any power

HI Rodders,

Bad news I'm afraid. The flat piece of metal that you describe is the back end of the central pin that has snapped off the inside of the power socket on your notebook. This is quite a common occurrence (check out some of the other posts on these forums).

Unfortunately the solution to this problem is for your nearest Authorised Service Partner to replace the mainboard (quite expensive!) unless you can find someone willing to solder in a new power socket.

Very sorry to be the bearer of such bad tidings.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

Answer:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

I bought a second hand R60e laptop at the beginning of the year for my son.

To power back on I have to remove the battery from the laptop and then put it back in. Then I can power back on but then I need to update the date and time in the BIOS. If I shut down without the power supply connected, then I can usually power back up OK. Sometimes the laptop will power off while in use - no power at all. Each time I have a problem I have to remove the battery before I can switch the laptop back on. The battery seems fine as I can run on battery for 2-3 hours ok.

I have terrible luck with random bsod's and power supplies pooping on me, I want to pick one this time that will last me. Also, I have my power running through a Monster Power HT700, I live in a new apartment so the wiring should be ok, I've dusted out all of the components inside the case, double checked my connections, all that jazz. I've got a cooler over my memory, I am still using my stock cpu cooler, but thats changing soon (I get crashes @ idle too) Any help I could recieve I would appreciate, thanks

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

Hello to the HP community. I must warn you all, this is a long thread and is potentially confusing, so only read this if you're interested in giving feedback. I am here today to not ask a question, but to share with you my confusion on your Pavilion desktop PCs. I've looked at the technical specifications for many of the Pavilion desktops, including my own, and I simply can't understand one thing; where do you get your PSU power ratings from? I currently have a Pavilion 500-319na:'s a good computer, powerful in most areas although the GPU isn't, so I'm looking to upgrade it. The first thing I check before I upgrade parts, and hopefully others do too, is the PSU's power rating. And this is where my problem lies. Firstly, your website states that for my PC, and others, it's an external power adapter. It simply isn't, as it's inside of the PC. I've seen in many discussions that this has confused people, including myself. And secondly, your website states that for many of the Pavilion PCs, including mine, the PSU is rated at 180W. Let me tell you why I believe is wrong: The PSU that comes with my PC, and presumably other Pavilions too, has four power outputs: 3.3V (12A) and 5.08V (10A) outputs, 'limited' at 70W. Then there are 12Va (7A) and 12Vb (10A) outputs. These apparently produce 180W. First of all, the 3.3V and 5.08V outputs can't be limited to 70W, in theory. This is because, using the equation...

depends on the spec of the bundled powersupply and the one you would buy seperately... they could be identical or different wattages... you just need to look at the specs i think!

I have a shuttle system with a small PS in it and want to run a RAID array off of it with 4 drives, which obviously won't fit in the system. But I can set them next to the system Ok and it will work. I'm concerned about power tho. Do you think I can get away with powering the hard drives with a stand alone bare PC power supply? What issues might I have?

I already figured out how to get the PS to come on by grounding the PS_On line. So I think this should work. Any comments?

Answer:Using a bare Power supply to power hard drives

Yes, tried it and all works. I thought that I might have to create a more local ground between the PC and PS to make sure the voltage levels matched but didn't need to. A shuttle system running with 5 hard drives and a DVD! Anyone beat that?

Hi forum and pc gurus,

My problem is specified down to my PSU, at least I think so. (550W Logisys PSU - maybe the quality has something to do with it, I paid $19 for it from NEW EGG). I have A Gigabyte GA-965P-DS3 Motherboard, a Intel Core 2 DUO Conroe 2.13GHz processor with heatsink and Fan, Sapphire ATI X1950 Pro, 2 GIGS of WINTEC DDR2 PC 6400 (800) RAM, 1 SATA Maxtor 320 GIG HD, 1 2.5 inch SATA 160Gig HD, and two DVD Burner Optical Drives (both IDE).

I have it hooked up like this, two Optical Drives connected to 1 IDE connector/cable which is hooked into the IDE input on the motherboard, both are set to slave. Two CD outs (connected one to each Optical Drives) to one CD input on the motherboard. Both HD's are connected to SATA inputs on the motherboard, one is set for master, one is set for slave (I heard that it did not matter but wanted to state that anyway), then my ATI RADEON X1950 is hooked directly into my only PCI Xpress 16 slot. The power connectors are then all hooked into their respective inputs on the drives and Video Card. ANd last but not least, all the Power button and LED connectors are hooked into their input on the motherboard, wich I set up exactly as the motherboard diagrams and directions directed. I turned the switch on the PSU to on and I only got a faint mouse like squeek, then nothing, not even the fan. So I figured it was DOA, so I had newegg send me another.

Hello and thanks for any help that can be given,I have developed a problem where my compute won't turn on most of the time. About a month ago my computer shut off on its own, and when I went to turn if back on it would not start, so I tried a different power supply it worked, so before I removed the first power supply I tried it again and it worked, so I left original power supply in computer. Then about three days later computer got shut off accidently got turned off when cat turned off surge protecter on me, (I know shouldn't have had it in a place that the cat could have been anywhere near it) went to turn it back on and of course wouldn't start up. I again tried othe power supply and this time no luck, so wouldn't start, I removed and reinstalled all wired, and still nothing, was about to give up, when I hit on/off switch one more time and it finally turned on. Computer stayed working until yesterday when the power went out on us, and of course I cannot get the computer to turn on. I know that both power supplies that I am using work because I tired them and they both worked on this computer I am using to type this. I also know that the motherboard is getting power because when I was resitting the video card a LED turned on telling me not to remove card because there was still power going to motherboard.

Hello everybody. I have a computer here that I was asked to fix, and was told that it wouldn't turn on. When I brought it home and first turned it on, it booted up with no problem, and thought that there was no problem. But, the next day it would not turn on. So, I swapped out a different PSU that I knew worked, but the computer still wouldn't turn on. I was testing different things with the computer plugged into a power outlet and sitting on my lap, and all the sudden I noticed that it had just gotten power, so I hit the power button and it booted up fine. Since then I haven't been able to get it to power up again, though.As of right now, the computer will not boot up, and only has one yellow light light on the motherboard which is the "AUX PWR" light.Any help would be greatly appreciated, thanks!

Answer:Computer Power Issue - Doesn't seem to be the power supply.

Well....the "AUX PWR" light means power is coming from the wall to the computer.You have already tried another PSU. Some now it seems it just might be the power button itself. The power button on modern PCs does not really send power to the system. Instead, it is a way to get the system to pay attention and start the power on sequence.But it might be another issue. Here is some ideas from another forum the fans connected to the motherboard, especially the one on the CPU fan header, I've seen a similar issue where the fan wouldn't register as rotating fast enough on the first "boot" but if the button was pressed again it would work (this was confirmed by manually spinning the cpu fan and it would boot first time).Does that help any?

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

Many thanks in advance.

Answer:extra power leads on power supply?

Sounds like typical extra +5V lead and can be used for any number of things...(riser cards,backplanes,to drive extra slots, etc.)
Without knowing the specs. on your motherboard this question is impossible to answer...Post Mobo identification (make/model) or obtain FCC ID and post that. Perhaps we can find a more definitive answer for you...BOL

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.

Answer:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Hello, everyone - I have just assembled a new build. It will not power up. I need a suggestion to figure out if the problem is the case or the motherboard.

This is a mini-itx build. The case is Linkworld LC820-01B. This case comes with a 12 volt 65 watt external, laptop-style power supply that plugs into the rear of the case just like a laptop power supply plugs into a laptop - a barrel connector. Inside, this power connection connects to a power supply component that is not like a regular ATX power supply, but is on a printed-circuit board mounted on the case. This has several capacitors and other stuff. From that comes the 20-pin and 4-pin power supply lines for the motherboard.

I assume the 12-volt power supply for this external power supply unit is right, since it came with the case. It was 65 watt.

The processor is an IBM 1155 3220t, with TDP of 35 watts. Lower-powered CPUs can be put in a small 1155, so I assumed the power supply might be under-powered. I ordered a 90-watt 12 volt power supply with the right size barrel - and same polarity (pos inside).

The MB is an ASRock H61MV-ITX. It is 1155, mini-itx form factor.

Still, same problem.

Everything is connected correctly.

When I press the power-on button, an external CD drive I have plugged-in spins up for a while. But no power light comes on in the front of the case, there are no POST beeps, the fan for the CPU does not spin up. No other signs of life.

So, power is getting into the MB - the external CD drive i... Read more

Answer:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Hi everybody,

I tried to search on google about this, but it's not really help and it never happen to me before so I post here.

My PC was running normally for a long time, just couple weeks ago I sent my faulty video card (xfx nvidia 8800 ultra) to get warranty service and they sent me back another. The new one works fine, but a week later I tried to turn on my computer and there's no power at all. No lights on, no fan running, just no sign of power. So I check inside if there's any wire from the PSU is unplugged, but everything looks good, nothing seems wrong. I'm sure the power from the wall is good and the power switch on the back is on. So I tried to check the wired again, push the power cable to the mother harder and press the button, it worked. But that doesnt solve the problem, if I put something heavy near the PC or the desk is vibrating a little bit, the power turns off. I press the power button again it would not turn on until I open the case and press the power cable to the motherboard harder, it's on. I then close the side panel, it's off, no power.
This is really annoyed me, I dont know what else to do. What caused this problem? The power supply or the power button? Can somebody help me?

Finally broke down and started building a new system -
I'm too old to game, this all started out as a home video

Anyway - gathered all my components, now I'm working
to assemble them.

The case came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what seems
to be it doesn't at all match the connector on the board.
And I've got that positively identified by the board manual.

The board has a small male 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the strings of
drive power harnesses. Nothing tucked up behind the
supply case or anything.

Is that likely to be it? Or would that be for a floppy or something?

I tried to Google for a wiring schematic, but could find nothing.
In fact, nothing much at all on this brand of supply - just
a couple places that sell them. Please don't tell me I got
an el cheapo that isn't worth having!

At the risk of getting ahead of myself, in case I need to adapt
something like that to the different style male connector on the
board, in this case or something else I may find as i progress,
is there some type of source for adapters, or what would I do?

Answer:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

This may also explain why the system seems slower than expected.  I'm trying to work with all the settings but some windows updates fail, some driver installations fail.  Not sure what the issues are here.I'm also seeing some strange bugs.  If I quickly try to reduce or increase the display brightness sometimes the brightness starts flickering and won't stop until I max out the brightness settings again.

my first thought was RAM, since it is more sensitive to power surges. changed out the RAM, still nothing. so i put the original RAM back in. cutting to the chase.... it turned out that the 3 addon cards went bad, video / sound / network. the RAM, CPU, MB, and hard drive were all fine, but all 3 slotted cards burned out. and it was like .... ummmm, oh well... electricity is a funny thing, and it would depend on how the wiring on the MB is laid out.
and one last thought... get a UPS battery backup. they are invaluable and a life saver!

My first post...

I received my new DVD DL +/-RW drive today and eagerly installed it. I of course unplugged my computer's power supply while doing it. After plugging the power back in, the green LED on the back of the CPU started blinking (never noticed this before), and when I hit the power button, NOTHING happen. No fan turns, no lights, nothing. When I unplug the power supply, the green LED blinking gets slower and slower, and after about 15 minutes it totally stops. I plug the power suppply back in and it starts blinking all over again and still the power won't turn on.

All I did was replace a CD-ROM drive with a DVD Multi drive. I didn't mess with anything else, so there should be no power supply shortage or problem. Any thoughts as to what could be happening?

By the way, I have a 2 year old Compaq computer with 2.0 ghz Athlon 64, 1 gig RAM, no problems thus far.

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.
