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?

Guess whos a fool. Appearantly the 4 prong 12 volt plugins are connected side by side for maybe dual processors or 2 processor systems. My 8 prong plugin easily split apart and it is working perfect. I had been using the wrong 12 volt plugin. The third one was for 24 pin processors.

Didn't know that would even fit? does the mobo still work?
