I bought an Antec TRUEPOWERII TPII-480 BLUE ATX12V 480W Power Supply from newegg.com and an ABIT KN8 Ultra Socket 939 NVIDIA nForce4 Ultra ATX AMD Motherboard. I'm a first time builder but when i got everything hooked up and start the thing, nothing happens. The PSU was on and hooked up so i don't think it was that. My case has 5 fans though (2x 90mm; 3x 80mm), but i figured that my PSU could power that. So eventually i made my way to www.abit-usa.com and checked the compatibility of PSU w/ the motherboard. The PSU I have was not listed as compatible. But under some reviews at newegg.com, people were running Antec PSU's.
I figure that a PSU should be able to power a 24 pin board since it has a 24pin power connector, but im a noob at building computers so i don't know wat to look for. Does anybody have any idea on whats going on. I'll answer any question u have.
