Question about Dell Optiplex GX280 (99301) Motherboard

1 Answer

Cannot find replacement parts

I work for a school's IT department. we have 30-40 dell optiplex gx270's and gx280's. recently many are dying. we have narrowed the problem down to being a faulty MOBO, and are looking into replacing them if we can find new or refurbished parts, however we have not been able to find any. Do you have any suggestions on where to look or is it not worth it?

    Have you tried to contact Dell's PR people and explain the situation to see if they could help you?



    Just a thought.

I am looking for a schematic for a Dell Optiplex GX280 power supply. The supply is model HP-U2106F3.


I just replaced my GX280 power supply (mini-tower) with the following 400W for $30.

The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

May be a cpu problem. Make sure the fan is on the cpu and that it is running. If the fan is running you may need to change the thermal compound that is between the cpu and heat sink. If that doesn't work , the next step would be to try to use another cpu that you know is good and see if it fixes your problem.

Will a dell gx280 motherboard fit into a gx260 (dell) case?


If it is a slim gx260 case, it might not. If it is the wide case, it will, but the two motherboards have different power supplies. You will need to use a gx280 power supply to power it on. However, you can use a gx270 motherboard in a gx260 case without changing the power supply.


Hope this helps!
