Dell OptiPlex 7020 on\off power pin assignments

Question: Dell OptiPlex 7020 on\off power pin assignments

So, my boss wants a remote power switch added to his Dell OptiPlex 7020 so he can pack it away in a cabinet but still be able to turn it on remotely, comfortably. I have no idea what the pin assignments are, pins look like this (box on side, front facing you, plug is in lower right corner of box):

I have an Optiplex 7020 that is not powering ON.
When I press and release the power button, I don't see any light in the power button as well as the diagnostic indicators.
When I press and hold the power button, amber light flashes continuously in the power button with a faint sound (I am not able to decide whether it is a clicking sound or beeps). There is no pattern in the light as well as the sound. They just go on flashing continuously (two counts per second). The light and sound stop when I release the power button.
On pressing the BIST test button behind the PSU, all fans spin at their max and stops on release.
I have tried swapping/ moving RAM to different slots but that didn't make any difference.
I couldn't spot any blown capacitors on the motherboard.
I have tried replacing CMOS battery but that didn't make any difference.
I am having a tough time with this and not able to isolate the problem to one part. Please let me know if I am missing something and if you know what could actually be wrong with this PC. Your inputs are highly appreciated.
Thanks in advance

I've reviewed the Dell client statement (Dell Client Statement on Intel AMT Advisory (INTEL-SA-00075) showing the summary of systems affected by AMT vulnerabilities and proposed BIOS/Mebx firmware updates, but the Optiplex 7020 is missing from that list - we have a large number of these systems deployed, and every other modern Optiplex system is present on the list.  Was this omission in error?

I work at a technical college and we did test pilot rollout of Windows 10 Enterprise 64 bit on 30 machines.  The installations worked except for one Dell Optiplex 7020.  We have one user that has to push the power button at least 4-5 times before the pc will stay powered on.  The POST usually gets past the bios splash screen and starts loading Windows 10 but then the machine shuts off.  After the 4th or 5th time the machine will stay powered on?  This machine did have Windows 7 on and it was working fine.

We deployed Windows 10 using Microsoft SCCM 2016.

Hello! I bought OptiPlex 7020 for gaming (since this is what i could afford) but the graphics card doesn't seem well suited for the purpose of gaming; so i was wondering if there are any Dell graphic cards available which can be compatible for games like World of Warcraft, and at the same time compatible for my device.
And if such cards are available, where in Egypt can i find your branches? Preferably in Cairo.

I have an Optiplex 7020 that is a couple of months old.  I started with 4G of RAM but have installed another 8 for a total of 12.  During operation, the motherboard speaker beeps at random times.  (This was true both before and after I installed the extra RAM.) There seems to be no correlation with what I am doing, and sometimes the beeps occur when I am doing nothing at all.  They do seem to occur more often when I am running a CPU-intensive tasks.  They are generally single beeps but occasionally occur in pairs or threes.  I've run diagnostics several times on both RAM and my hard drive, both the BIOS diagnostics run by hitting F12 on boot-up and the diagnostics available at  Always they turn out fine.  I've also upgraded the BIOS to the most recent version.  Any help would be greatly appreciated.

We use a master image at work to set up all our Dell computers. Worked on my first Optiplex 7020 today and after cloning the drive and running the initial Windows set up, both the USB keyboard and mouse ceased to work on the first boot into Windows. I could boot into safe mode and they worked fine, but rebooting into normal mode wouldn't change. I tried all the USB ports available, also tried a PS/2 mouse and keyboard.
I eventually downgraded the BIOS from A07 to A06, no difference. Then I downgraded from A06 to A05; voilà, keyboard and mouse are now working fine.
It could be a driver issue in our master image and something specific in the BIOS. Just posting this in case anyone else runs into a similar issue; downgrade the BIOS.

As per title really.  I have been able to log in using a PS2 keyboard and mouse, and the USB Root Hub driver is exclamation marked.I feel I need to provide some background information.  How I go about creating an image for a PC is basically building any new model fresh from the ground up.  Install Windows, install drivers, updates, and any relevent software that would go in a 'gold' image.  The PC is sysprepped, and that sysprepped hard disk is then imaged as a deployment image.  With the occasional workaround here and there pertaining to different models, this has worked just fine for us so far.  The sysprepped hard disk is imaged using clonezilla, then the image is distributed to our technicians for their portable hard drives.  This is a solution we have been using for years without too much headache until now.
We use this method of imaging because the images can be portable.  We have 85 sites over some fair distances, all of which means that bringing a PC back to HQ to be reimaged when required isn't particularly feasible.
On our 7020s, once we've cloned the image back onto the disk, when we get to the screen where it asks for our computer name (which woud be the asset tag of the PC in our case), I cannot move the mouse or type anything.  There is no indication of life from either peripheral or any life from my usb hard drive).I've tried creating a distribution share on the local drive and have the unattend.x...

Dell Optiplex 780, Ultra Slim Desktop case. Refurb purchased from NewEgg last November. Son added a graphics card this spring. Worked a while, then he had power up problems. I pulled the hard drive and scanned it while connected to another computer as an external drive, expecting to find a virus. WebRoot had expired, did not bother to let me know. No virus found. Reinstalled the drive. No success at first. Later, he had it working. He cannot tell me exactly what he did. I had him pulling and reinstalling memory, drive cables, etc. to check for bad connections. Now, after working for a day, it will not power up. Got a copy of the Dell service manual. The pc has passed the power supply tests. We found a helpful video.

Power light: solid amber
Diagnostic lights: 2, 3, 4 are on

This is listed in the Dell service manual as a possible USB failure. No peripherals are connected (not even the keyboard). If a USB port craps out, will is stop the pc from booting?

A blinking amber power LED usually indicates a failed power supply, replace the power supply with a 'known' working unit, to see if this makes a difference.
Which version of the Optiplex 390 do you have, the Mini Tower, Desktop, or the Small form Factor?

I have a Dell Optiplex GX620 minitower that was working just fine until a couple of weeks ago, no problems at all. One day, however, it wouldn't power up; instead of the green power light, I got a blinking amber light. I tried unplugging everything from it and letting it sit for a bit, but it still won't power up, and it still gives me the blinking amber light.

I have checked the chassis intrusion switch, and I have replaced the motherboard. I've also verified that the power supply is functional. We did try unplugging the memory and video cards, and it still won't work. We also checked that all of the USB ports seem to be fine. We also tried a different power cord. None of the diagnostic lights come on at all.

Any more ideas?

Answer:Dell Optiplex GX620 won't power up

A blinking amber light on a Dell is almost always fixed by replacing the power supply. You said you verified yours was working but didn't say if you tried another. I would try another power supply.

Hey,Dear i have problem with my desktop dell optiplex 9020 the problem is when i tried to power on it is not powering on but i can see that the power button is still orange but it is not powering on.

Answer:Power issue with dell optiplex 9020

Hi ,
Thank you for writing to Dell Community Forum!
Here when the power button is  orange it indicates that the system is receiving power but not sufficient power to transmit it to the system's components.
However I would suggest you to try these steps and advise the result ,
*Disconnect the system from wall socket and press ,hold the power button where in we are releasing the static charge from the system ,then connect the system back to the wall socket and turn on the system .
*To confirm if the power supply unit is working fine would ask you to perform the power supply unit Built in self test where in behind the system where the power cord connects to the system you will be able to see a tiny black button with a green radial bulb next to it .When that button is pressed if the green light glows then power supply unit is working fine.
*Confirm the power button has a steady orange  light or blinking orange and also if you hear any beeps from the system .
Can you also provide your computer model ,service tag of the system (via private message) to perform model specific troubleshooting. Hope to hear from you soon.
Have a great day ahead !
Kindest Regards,

Hi all, new here and not very technological so be gentle.
I have bought an old Optiplex 380 SFF to use for a homemade arcade cabinet project and need some wiring advice / help. Basically I want to add and illuminated arcade button to act as the power switch when the cabinet is built as the computer will be inside and not accessible.  As these computers do not have traditional headers / pins for the power switch I am stuck as how to achieve this. Looking at it I believe that the ribbon connector that connects the power audio USB front panel to the motherboard would be a good place to look, dell part number UM941. Ideally I would like to isolate the + and - for both the power switch and the power led within this ribbon. Does anyone have a wiring diagram for this part number? Or a pinout for the motherboard and the front panel? Motherboard part number is R64DJ and front panel is XW055

Connect to power and it does the power cycle repeatedly. Normally you have to wait a couple of seconds while the lights flash then you can press the on button. This just loops that cycle.
I've tried a different power supply, no change.Three times out of many after I pulled the CMOS battery, disconnected cables and pushed power button it booted and I reset the BIOS and made sure it wasn't set to power on with a reconnect to AC. I ran the full diagnostics tests including memory without a single fail. Yet on reboot. Fail.
Any help? I'm in the DR Congo so don't suggest taking it to my nearest service agent as I'm the go to person for a thousand kilometers in any direction.

Answer:Dell Optiplex 780 can't get past power up cycle

Hi Stillblue,
Check the power LED and diagnostic LEDs on the front of the chassis next to the power button . What is the colour of the power LED? Is it steady or blinking? Also, check which of the diagnostic LEDs are lit. These diagnostic LEDs are only active and visible during the POST process. Once the operating system starts to load, they turn off and are no longer visible.
You can also check the troubleshooting steps mentioned in the link below.

Answer:power supply over heated on a dell optiplex 740

Do you mean "heat sink" rather than "power supply"?
You didn't say which form factor 740 you have, mini-tower, desktop or small form, but go here and look at the motherboard diagram for whichever model you have to find the location of the fan connector on the board.
Make sure the PC is powered off, unplugged and you press/hold the power button for ~15 sec before you do anything inside the case.

When plugged in the light next to power is green.
When you hit the power the power light goes blue and the  light above the power is white for 4 seconds.
Fan starts up for 1 second and nothing else happens. nothing on the screen at all  (normally)
sometimes when you push the power the fan starts for a second then dies then for the next few minutes it trys to start with fan going from 1 second then dead, fan for 2 seconds then dead, fan goes 10 seconds and then dead,  almost like a car engine not getting gas but trying to start up.
Whole time it does this the power light stays blue and the light next to the plug is green.

My guess is a bad capacitor on the mother board or a bad PSU.  This being a AIO I would have to order direct from dell or off ebay.  So would like some more info being putting another $100 into a brick

My refurbished dell optiplex GX280 worked fine until a month or so ago when I moved it to another room in my home. When I powered up, the power light was blinking amber. I tried all of the options that did not require buying new parts du to financial reasons, so it's sat since then.

I just decided to look at it again and powered it on. Everything seemed to start OK but no dispay. The diagnostic lights indicated faulty memory. I then located and removed the faulty DIMMM, and it started right up.

About ten minutes later the computer shut off by itself back to the blinking amber power light. :evil:

Thanks for this forum!  I am having trouble out of a number of Dell OptiPlex 9010 AIO machines that are deployed on my network.  They are all running either Windows 10 Enterprise version 1507 (original release of Windows 10) or Windows 10 Enterprise version 1607 (Anniversary edition).  All 64-bit OS.
The issue is that even though I have configured the systems not to ever go into a sleep state, they are still doing it and when they do, the only way to wake them back up is to hold the power button and recycle.
These are older systems, so I am considering replacing them but I'd like to know if anyone has encountered this issue under this config.  I have tried different BIOS revisions including the latest and have tried different combinations of drivers as well.
Thanks for any advice and If there is additional information that I can provide that would be helpful, please let me know and I will respond.

Answer:Dell OptiPlex 9010 AIO - Power Save/Sleep Issues

Reboot and immediately press F2 to open BIOS setup.
Enable USB Wake which is disabled by default. Be sure to save the change before exiting setup. That should allow mouse or keyboard to wake the PC from sleep.
And if you need even more control, go to the Power options screen in Windows, select the active power plan and change the settings for sleep and hibernation to Never, but set monitor and hard drive to turn off after a set time. And on the Advanced settings screen in the Power plan, turn Hybrid Sleep off and disable USB Selective Suspend.
And you may also have to go into Device Manager and expand the list under USB. Select each root hub and click its Power Management tab. On that screen uncheck the box "Allow PC to turn off....". Do that for all root hubs. Then expand list under Human Interface Devices and uncheck that same box for any entry that has a power management tab.

I have a Dell OptiPlex GX280 mini-tower (smallest one thereis), and the original 160W power supply died a few months ago without warning. I ordered a new power supply, but accidentally ordered the wrong size (210W for one of the larger towers). I used it in the meantime until I could get the proper size (although the 210W supply wouldn’t fit in the mini case – I left it out of the case and ran the wires through the power plug hole). The computer booted up just fine with this 210W power supply. I finally got around to ordering the 160W smaller correct size, but that power supply would not boot up the computer (just got an amber flashing light). Thinking it was just faulty, I sent it back and requested a replacement. The replacement did not work either. I ordered a third replacement, and the third did not work either! So now I am back to using the 210W power supply (No. HP-U2106F3) which does not fit in the computer housing. I know these Dell OptiPlex machines are notorious for having power supply and capacitor issues. But the question is, why will the computer power on using the 210W power supply? I contacted Dell and they were of no help whatsoever. The guy told me that 160W wasn’t enough to power my machine and to order a 210W power supply correctly sized for my chassis. Gee, thanks! First of all, they don’t make 210W that fit in the mini towers, and second of all, why did it used to work just fine??? Oh, and no I have not upgraded anything (i.e., video card, etc.) which...

Answer:Amber power light of death flashing Dell optiplex gx620

Hi Eddysam,
Please check the power button if it is solid or flashing, is there any pattern for the same. Please check the keyboard caps lock and number lock key if it toggles while the system is turned on.
For me to better assist in troubleshooting, please click my DELL-username and send me a Private Message with the Dell Service Tag number and your email address.

I am new to this excellent forum and wondered if anyone out there could possibly help......

I have a Dell Optiplex GX620 Desktop PC. Several weeks ago I had a slow flashing amber power light, indicating a PSU or switch fault. Firstly I replaced the switch - made no difference. Then I replaced the PSU - The slow flsahing amber light has now changed to a blinking (very fast) GREEN light on the power button.

All of my research so far has suggested that this suggests the PC is in standby mode! But the PC isn't even switched on - no fans running etc. In desperation I have even plugged a USB mouse in to see if I can "wake" it up! I have a amber AUX_PWR light on the Motherboard which is on.

Nothing happens when I press the power button - no matter for how long I press it in!

Has anyone got any ideas?

Many Thanks in advance

I have an old Optiplex GX240 that had its power supply break, I recently got another power supply from a different computer. The Power supply is working however there is an orange light on the motherboard and power button that doesn't flash. The ABCD lights on the back of the computer are also not lit.

Answer:Orange Light On Power Button and Motherboard - Dell Optiplex GX240

GX240 requires specific NON PFC power supply.  This unit is 16 years old now and has 512 meg ram of the PC133 variety.   A newer model like an optiplex GX620 or better is still viable.  This system is TOO OLD and TOO Slow to be of any use.

I bought this a couple of years ago from a local computer store. It's been very reliable and I run Ubuntu 16.04 Linux on it. This afternoon I had a power drop of a second or so and since then when trying to boot the issue in the subject happens. I can get to boot as usual by pressing the power supply test button which gives me a green light on the power supply and then pressing the power button will let it boot normally. I don't have any version of Windows installed so it's not possible to run any diagnostic unless there are some Linux based ones.
Thanks for any help

Answer:Dell Optiplex 780 MiniTower, power light flashes amber diagnostic lights 1 & 3 flash

Blinking Amber power: Initial state of light at power up. Indicates system has power, but the POWER_GOOD signal is not yet active. If the Hard Drive light is off, it is probable that the power supply needs to be replaced. If the Hard Drive light on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic lights for further information.
1+3:  Memory modules are detected, but a memory configuration or compatibility error has occurred.
You could try resetting BIOS to see if you can clear the error.

Reboot and press F2 to open BIOS setup
Copy down all current BIOS settings
Power off, unplug
Press/hold power button for ~15 sec
Open case and remove motherboard battery
Press/hold power button for ~30 sec
Reseat RAM modules in their slots
Reinstall battery- good time for new CR2032 coin cell, if this one is old
Close case and reboot

If that helps, go back into BIOS setup, and confirm that all settings match what you wrote down. Be sure to save any changes before exiting setup.

Dell OptiPlex 9020 SFF 
system won't show screen, power led is white, cpu fan revs, but not loudly.
Dell Support were friendly & helpful but didn't get me anywhere, so it's DIY :-).
Power supply test (button on PSU) runs OK when turned off and PSU led is green, so not a power supply problem.
Shutdown and remove power for 1min - no change.
Disconnect HDD, AMD graphics card & DVD & one (of 2) memory module- no change.
Remove both DIMM, pwr on - system beeps - good motherboard is alive :-)
Disconnect power, remove last Memory DIMM & swap for the other one & system boots into BIOS Menu (as there's no disks to boot from)
Pwr down, connect HDD - Pwr up -no screen, no boot. (After this you're back to a dead PC agian)
Long story short - ONLY if you change the DIMM & leave ONE DIMM by itself THEN will system start, but not if any disks are connected. (if you only have one DIMM use Slot2 which works)

Machine : Dell 7020

I am having a bit of a challenge, I am trying to install  D-Link WIRELESS N 300 PCI Express DESKTOP ADAPTER in the above machines.
When I insert the card and try to install the drivers, I get a fuzzy screen after a windows start up.

And this is just not happening to a single machine, I have tried different PCs same make, different cards but the same effect. I have followed the installation procedure to the letter but I still have the same problem.
But when I tried the card on another PC but it worked there. Has anyone ever experienced this before or can someone point me in the right direction in order to solve this problem 
Any advice is highly appreciated

Answer:Wireless Adapter Failing to Work on Dell 7020

Greetings Islug!
Thanks for your question. I will assist.
First, I have a few question.
1. I assume you’re running the minitower version of the 7020. Correct?

2. If you’re running the minitower, have you tried popping the D-Link card into the x4 slot instead of the x1 slot? You may have the same problem there. I just want to know if this has been tried or not yet. The x4 is show below, outlined in white. The D-Link site says  " You can connect the Wireless N 300 PCI Express Desktop Adapter to any PCIe slot in your computer, whether it is an x1, x4, x8, or x16 slot."

Hello, I own a Dell Optiplex 745, running Windows XP Professional 32-bit. The Dell System Direct isn't launching, even though it will download, it says .APPLICATION, which cannot be opened. Does anyone have a fix?

Answer:Dell Optiplex 745 - Windows XP Pro 32-bit Dell System direct issue.

The older versions of Dell System Detect are security risks - if you're running an antivirus program, it may be flagging and intercepting the program.  At any rate, you should NOT be using Windows XP online at this point, as it has seen no security updates in almost two years - you really need to upgrade to a supported version of Windows (at this point, that's a minimum of Windows 7).

When the PC starts up, the dell loading screen begins. Normally this takes around a few seconds but this time it didn't end. We've tried all the diagnostic tests and they all came back fine. Also tried disconnecting all external cables (ie headphones, ethernet etc). Powered on and off multiple times and no change. 
By the way, I don't know if this is related or not, but last night before the issue occurred, I was randomly logged out. Once it logged me back in, everything was closed and there was a small square of like TV static towards the bottom right corner. I restarted and it fixed the issue there but I don't know.

All of the other equipment sharing the same power strip come on but not the desktop so it is not the power strip.  I also tried to set it up in another office on a completely different circuit and still does the same thing.

Sounds like a faulty hard drive is the cause - F12 at powerup.  Boot to the Dell diagnostics and run an extended test (not just the quick test) on the hard drive -- you'll likely find it fails, in which case - replace the drive and reload.

I have 4 ext. usb 3.0 drives in dual docks that are part of my backup box setup.

Answer:Ext, USB Drive Ltr Assignments change Int. Drive Ltr Assignments

As far as I know if you assign the USB hard drives letters far outside the normal range of drive letters they will always get those letters when connected. For example, start at Z: for the external drives and work your way backwards.

Answer:Help With Dell Optiplex 745

Minitower Optiplex 745:
Supported microprocessor types: Intel® Pentium® 4, Pentium® D, Celeron®, or Core™ processor
DDR2 RAM should be installed in matched pairs so you'd need to install 2 of them. But there's no point installing 4 GB of RAM with a 32-bit version of Windows which can only use ~3.0 - 3.5 GB of RAM. Note, this system supports 2 GB RAM modules but only those running at 533, 667 MHz. It doesn't support 2 GB modules running at 800 MHz, but apparently will support smallar modules running at 800 MHz.

There's not much you can do with these as far as gaming goes - the power supplies are not going to handle demanding video card, and the chassis and mainboard are both proprietary.  
It'll perform just about the way you expect a nearly decade-old system to perform -- if you want the best you can do within the limits of a decade-old processor, replace the hard drive with a solid state drive.

Question: Dell Optiplex 780

I like my ten year old computer.  I've tossed the original 250G HD (and Windows too) in favor of a 1000G HD with Linux Mint 18.1.  It behaves perfectly and is quite fast.
I greatly appreciate the quality of the case.  Nice metal which is easy to open without a screwdriver.  But I have some questions.  I understand the maximum RAM is 8G.  Does anyone know if this is true because I want the maximum whatever it turns out to be.  
I rescued this computer from recycling and bought a new monitor for it.  Why anyone would throw away such a nice computer is a mystery to me.  Sure the display output is analog but there are two unused PCI slots.  I can add a digital card with HDMI plug I think without using an external converter which requires it's own power source. This way I can use my smart TV as a monitor.  Do I need a wireless card?  If it were a laptop I'd say "yes" but since it will never be moved around why bother?   I will add a graphics card though to get a visual boost.  I have no need for a high end gaming machine.  I'm in my 70s and low end games are all I can manage.  Besides I do not care for the violence that most of them seem to thrive on. 
If anyone can verify the max RAM I will be grateful.

That PC uses SATA drive controllers . . Installing XP on a SATA drive requires an additional step:

However, Most newer BIOS allow an Alternate method for SATA . . Go into the bios and check the "Sata Operation" setting,

change it to "Raid Autodetect/ATA if it is not already. Now try to install XP ( could be IDE Mode, Compatibility Mode or Legacy Mode - different BIOS use different terms )

some will say IDE instead of ATA)

If there are no such settings you'll need to slipstream the sata drivers on the XP CD, follow the instructions in this guide :


You can get a reinstallation guide specific to your Dell here

Are you using the Dell Reinstalltion disc? . . if so is it SP3? Those have the Intell SATA drivers

Question: Dell Optiplex 745

Which graphics card could i use in a Dell Optiplex 745 maybe a EVGA GTX 750 Ti? Or is there somethings different i could use?

Answer:Dell Optiplex 745

It depends on your case, the specific card and the power supply you have.  That card is overkill for a system that old and a CPU like the Core 2 in it.
You'll need the minitower case at minimum (forget about the smaller ones) and may need a new power supply if yours isn't up to powering the card -- or if the card requires a separate power tap, which your power supply will not have.

Hi all,
I've got a Dell Optiplex desktop (DT) 755 at home which I'm in the process of converting into a PFSense router and firewall. I've got gigabit fibre coming in, and I'm noticing throttling at around 700mbit speeds, which I believe is down to the PCI bus.
Question is - can I use the PCI-E x16 in PCI-E x4 mode for a network adapter instead of a video card? Would an Intel EXPI9402PTG2L20 Intel Dual Port Gigabit PCI-e Network Card SFF fit the bill and what can I expect in terms of speed? Even PCI-E x1 would suit my purpose.
Any experience doing this would be helpful, I'm on latest bios version A21

Answer:Dell Optiplex 755 PCI-e

No you can only use the X16 slot with video cards.
if you put a NIC in you will be greeted with this.

I need information about the following:
I owe a Dell Optiplex 745 sff running Vista Business,
hard disk is a 80 Gigabyte sata
The hard disk is almost full and I wish to take it out and replace same by a 2.5" sata hard disk.
Can anyone tell me whether this is possible and if so how to go about it?
Because it's a small form factor it can only hold one hard disk.
Your advice will be highly appreciated and thank you beforehand.

I just purchased a (barely) used Optiplex 960 from my office (my employers often sell used equipment to employees if they want to get rid of it).  It's in great shape, clean, and all the hardware seems to work, except for the fan speed controller.  I know it's supposed to adjust the speed of the cooling fan depending on how hot the CPU is getting, but it's not doing that.  The fans seem to stay on low / medium speed even when the CPU is pushing 70 degrees C according to Speedfan...which is WAY too hot.  The only way I can get the fan to speed up is by disabling the auto-speed control in the BIOS and leave it on 100% constantly. 
Anybody have any suggestions?  Is the temperature controller damaged, or do these systems normally run hot?  Thanks!

Hi everyone,

I have been looking up about getting a replacement for my existing CPU which is an Intel Core i5 (Version: 2400) and upgrading to the new Intel Core i5 4460 which does support HD better for what I needed, such as movies and gaming (I only need up to 60FPS).

But other than that, I have been looking either at a portable GPU. The GPU is called a Zotac GeForce GTX 960 4GB (from NVidia). I just want to know if this will fit and will it work well with my PC?

I just want to know if the new Intel Core i5 4460 will fit in the Optiplex 390's motherboard, the same for the Zoatac GeForce GTX 960 4GB GPU.

But I would be interested to see what you have come up with any other CPU/GPU recommendations for this Dell Optiplex 390 Desktop.

Many thanks,


Answer:New CPU/GPU for Dell Optiplex 390

Because the optiplex comes in three form factors, which one is it? The Desktop ones? or the smaller one?

Anyways, to be able to upgrade to a Haswell processor you'll need a new motherboard aswell (Those with H81 chipset will do). The Zotac GTX 960 will work provided you have enough juice from the PSU to be able to supply the graphics card

Posted about this in the linux forum and software forum. My questions related to linux, operating systems and hardware... thus my multiple posts. Hopefully the mods don't get fussy with me. Just hoping to get answers.

I recently acquired 9 Dell Optiplex Gs+ computers. Anyone out there have experience with these things? Apparently they were being used as servers before being decomissioned. I've now acquired them and i'd like to hear from people who have used these before.

I'm posting about these in a number of areas because i've got a number of questions about them. I've already done the google thing and did research on them to see their specs, so i'm looking now to hear from those who have used these before or who may still be using them.

128mb ram max, simm edo
133 to 200 mhz intel processor (socket 7)
Hd space on these things are very small
They have built in 3com nics
Video type SVGA
Video chip set S3 Trio64V+ 86C765
Video memory 1 MB standard, upgradable to 2 MB

1) What are these units commonly used for? These particular units were in use by a local library, although i didn't learn what they were using them for.

2) What windows OS would run adequately on these boxes? I THINK they were running win NT but i'm not sure. How would win98 sport on these things? How would win NT server do?

3) Suggestions on what i could use these for in a network? I'm just looking for ideas... and no... giant paperweights or foot rests are not among the answers i'm loo... Read more
