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.
