Possible Incompatible PSU???

[thetallengineer]

Here is a quick summary of my problem and observations:
A few months ago I came home from work and found that my computer was off and would not turn back on. I plugged in an older CompUSA power supply I had laying around and it turned on. So I sent my Antec PSU in for an RMA and was given a new True Power Trio 550 to replace my previous generation Antec True Power 550w. Within two weeks of using that new PSU I came home to find the same scenario. So I once again sent in the PSU and was given a new one two weeks later. I plugged it in and within 2 mins my computer shut off. I stripped everything from the computer and used my old CompUSA PSU during my process of elimination test searching for a faulty component. I never had a single problem with any power loss while using that older PSU. When I plugged in my new PSU it booted up but within about 10 mins of use it once again died. The only thing I had connected was my graphics card, CPU, Motherboard and a flash drive running Knoppix.


My hardware:
Asus A8V Deluxe
AMD 64 3500+
XFX 6600GT AGP
Crucial Ram


It seems that if the only thing I change is my power supply that I get a failure. But I have used 3 different new PSUs of the exact same model and had the same results.

Is it a socket 775 or 939 CPU? I am not sure about the A8V series or that model and about which models it can hold. Try doing some research on it.

Socket 939. I have been looking for advice on what would be a better PSU for that combo but haven't found a definitive answer.

My old PSU was this: Antec TRUEPOWERII TPII-550 ATX12V 550W

They gave me this when I did the 2 RMAs: Antec True Power Trio TP3-550 ATX12V 550W

Wow. That's odd, man. I'm using an Antec Neo HE 500W on my S939 mobo.

Anyone with similar hardware that can recommend what PSU has worked for them?

Antec is junk. Get a Corsair 620HX.

[thetallengineer]

I will look into the Corsair. Any good reviews of PSUs specific to the AMD 64 line? Forum stickys? AMD Certified PSUs?

to date the Corsair is the only PSU that has passed the [H] torture test

It sustained a full 620W load under 50C for a full 8 hours without flinching.
