Re: repair psu for gx280

I have had several issues with this same problem, you may need a new power supply, because your old one may be failing and may need replacement.

My solution to this problem is that you may need to buy a need psu. I recommend either calling dell or buy a new psu.

I want to upgrade my power supply for the dell gx280 small desktop

Sorry to say that a 260w PSU is the largest PSU you will get for this system as that is all the M/B is safely rated to any higher than that and it may cause a fire or worse. I run a Dell GX270 and this is maxed out on a 260w PSU. This system will only be upgradeable to these specs :

3.2Ghz CPU ( Note they must match existing letters on CPU.
3Gb Ram under XP, 4 Gb under Vista or Win 7. ( Note win 7 will run very slowly )
256Mb PCI Card or 512Mb AGP (4X or 8X )
DVD Burner max ( Blu-Ray will not work as it is too advanced ).

Even the tower model of these systems only have a 260w PSU max due to limited power rating for the M/B. Tower PSU is able to be swapped out just like any other tower but the fact remains that the M/B is only rated to 260w and if you use a larger PSU it may cause a fire or worse. I hope this helps.

I want to remove physically a network card in my pc GX270 but i dont know which one is network card

For newer systems, network cards are "integrated" in the motherboard. If you are sure that you have a seperate PCI network card device, It should look exactly like this. Check the locks before pulling them out. Make sure that the pc is off and no flea power. Touch the metal sides of the CPU casing as this discharges any static electricity which is harmful for any electronic device.
Hope this helps.

Compatibility of PCI-EXpress card for Dell GX280 (Small Dextop)

So if this is a slimline pc you are kind of limited in upgrade options
space being the biggest , then being followed with cooling ability, the best advice I can give you if specs say 350 is needed i wouldn't chance having the card pull more of a load off of the PSU than what is rated for it. Hope this helps

Updrading power supply of Dell Optiplex GX280 Small Desktop.

Hi there.
No, 400Watts will not affect your computers performance, it just means that you will be able to add more peripheral devices to your PC, for example, an external or internal hard drive or more USB devices.
Make sure you get the power supply from Dell themselves as you will find it difficult to install a standard PSU (power supply unit).

Good luck and thanks for using Fixya!!!

Power is shutting down with orange light flashing on t

Hi, This is na very common problem with these Dell machines. I have found one of two things are the cause of this. 
1. Your memory warms up once system is on for a while and fails to make proper contact on all pins, focing system shut down (after which only a power disconnect will restart system).
Solution. Carefully remove memory moduls and wipe copper contacts gently with a damp cloth after which you can replace the modules firmly. make sure power to the system is uplugged during the entire peocedure and give the system 5 minutes after putting modules back (just in case moisture from wiping remains).
2. Your PSU (main power supply) is failing. Replace PSU (cost around $50 at local IT shop).

Hp media centre m1180n wont power up after power cut

most likely it was the psu. You can actually test it yourself by buying a psu tester made by Antec that you should be able to buy in stores. It's a cheaper alternative to buying a PSU and just hoping that was the problem.
