HX520 problem?

Hi Everyone,

 

I just built a new machine and I'm having a frustrating problem that I am afraid might be the power supply. Sometimes (not always) when I turn on the

computer the lights and fans come on for 3 - 4 seconds then shut off then

the computer restarts itself. When it does restart itself most of the time it

boots normally. However, at least twice now its seems to get caught in a on then off again cycle that continues till I hit the power switch on the PSU.

 

Help, I've never encounter this type of problem before in a new build. My

machine specs are:

 

gigabyte ga-p35-ds4 rev 2

Intel 6750

4 x1024 DDR2-SDRAM PC2-6400 Muskin

Nvidia GeForce 7800 GT

2x 500 GB Samsung HD501LJ

CORSAIR CMPSU-520HX

ANTEC 900

SAMSUNG 18X DVD Burner

 

Any ideas? I've look through the forums and I've seen a few posts with somewhat similar problems but nothing concretely identifying the problem

(and hopefully a solution!). :biggrin:

There are 2 possibilities. One is that the PSU is tripping the "Over Current Protection" or "Over Voltage Protection" due to an out of spec signal from the motherboard. The second possibility is that there may be a bad component in the PSU.

 

Before having the PSU replaced, if possible, you may want to test it in a known working system. If it gives you the same issues, we would definitely want to have it replaced, however if there are no problems in another system, you may want to RMA the board.

Thanks for the suggestion. I don't have a second computer to test the psu in, but I have managed to borrow a known working powers supply (a antec 430 earthwatts power supply). I've swapped in the antec and it seems to be working. (I'm using it now) but my problem was intermittent (largely showing

up after the computer has been off a while).

 

My plan is to use the "good" power supply for a while and see if the problem

shows up again. If it does, then I am guessing that the problem is with the

motherboard. If the problem does not show its head again can I assume

its the hx520? or is the only real way to diagnose that problem is to find a

second machine to use it in?

 

Thanks in advance and I'll follow up with any new information.

 

*Update*

 

Well that didn't take long. I encountered my boot problem using the

Antec PSU. So its not my corsair power supply (which makes me happy)

but now I'm going to have to RMA my motherboard. Good thing I

still have 6 more days to RMA it to newegg.

 

Thanks for all of your help!

 

Sincerely,

John M.
