I just completed putting together my new system, based around the Athlon 64 X2. It has a Biostar TForce4 SLI board, 2 gigs of Corsair DDR 400, and a Gigabyte GeForce 7800 GT. My question is about the 550 watt power supply that I'm using. The power supply has 20 pins on the mainboard connector, but the mainboard looks to support 24 pins. The 20 pins fit, but it leaves the extra 4 pins out. The additional seperate 4 pin ATX power connector (not part of a 20+4 pin connector which I've seen online) is plugged into it's appropriate slot.
While the computer does power on, it does not start to boot up. It does not beep (I beleive this is called posting?), and the LED indicators on the mainboard indicate, according to the manual, "Abnormal: CPU / Chipset error." So, I'm wondering if this could be because of the lack of those 4 pins from my PSU's mainboard connector, or do I have other (probably more serious) problems? If it is because of the mainboard connector, is there an adapter to go from 20 to 24 pins, or would I need to buy a (another) new power supply? Thanks.
