Hello, i'm building my new system but i've run into a problem. On my Gigabyte GA-P35-DS3L i have a spot for a 24pin ATX Power connector, but my Coolermaster Extreme Power 650W ATX 12V V2.01 Silent Power Supply 20/24PIN 120MM Fan only seems to have a 20 pin connector. There is a seperate 4pin connector, but i think it's supposed to go in the separate 12v atx connector by the CPU. Did i get the wrong PSU, or am i just not doing it right? I tried connecting the 4 pin to the remaining 4 pins on the 24 pin atx connector on the mobo, but the computer didn't boot up. All the fans spun, but the hard drive only spun for abot 1/4 a second. Couldn't even get into BIOS.
