funny story.... i had a nice trusted 600watt psu that is used and i was gonna put it in my new PC, and when i did i was really stupid and plugged the 6pin pci that it had into my 8pin to power the CPU, once i pressed the on button sparks shot out and broke the psu and my electricity in my house went out lol. i didn't read any manuals or anything so i didn't know what to do, and it turns out that you could also use a 4 pin connector for the CPU, and that is now what im doing.
