I recently added a second video card for an SLI configuration in my computer, and had to purchase a new power supply as well for it to work. The power supply purchased was a Kingwin ABT-520MA1W. Everything seems to be working fine except for my PCI cards; Windows XP no longer recognizes my Audigy 2ZS sound card or my Creative 56k modem as even being plugged in. Unfortunately, that is the only means I have to access the Internet from that computer. I did have to change which PCI ports they plug in to, but aside from the video cards, no other hardware changed. Re-installing the motherboard, modem, and sound card drivers did not help.

I checked the power supply's manual, and it does not mention a Socket 939 AMD-based motherboard as being supported (K8 933, 945, & 955 and K7's are). I am running an AMD Athlon 64 X2 Dual Core 4200+ on an ASUS A8N SLI Premium motherboard.

My best guess is that the PCI ports aren't getting power, but everything plugs in (except the Intel EPS +12V connector). Is there another way I can check to see what is going on? I'd simply return the P/S and buy a new one but Newegg.com does not list any motherboard compatibilities with power supplies; I would simply be guessing.

Update: I plugged my speakers into the motherboard's ports and a voice said "system failure...[unintelligible]." The P/S smelled like it was starting a smoke check, so I cut it off and gutted it.

I put everything back into original configuration, removing the new video card and installing the old P/S, but now my system won't even pretend to turn on. The green light on the motherboard lights up, but the power button might as well not even be there.

This is beyond me, so I guess I'll take it to some repair guy to find out what exactly is fried before buying more parts.
