okay i just bought a new motherboard today at my favorite computer part store. i got the Asus M4A78 Pro. to replace a dead mobo that was killed by..... a bios update........ dont ask on that one. now this system has a 550w power supply. it also has a amd phenom II x3 720 which is a 95w cpu. i have unplugged everything else and was going to take a look at the cmos settings, i had a few fans hooked up as well (2 to be exact) and the system will not turn on, so i unplugged the fans and tried. it worked! kinda..... so i have tried scouring the interwebs for the power reqs for this board, anyone able to give me a hand ?

and if i confused anyone please ask questions thank you in advance.
