New power supply
I got me a new power supply due to my upgraded video card. The old one works fine, but 300 watts just seems so low, so i bought this
Rosewill RP600V2-S-SL 600W SLI Ready-ATX 12V V2.01 Power Supply 115/230 V CSA,UL,TUV - Retail
Im looking for some help, when I turn it on all of the fans on the motherboard and power supply work just fine. But the mobo does not post. I put the old power supply back on and it posts. /cry. Any ideas?
