right i might risk sounding like a total window licker here. butare there different forms of pin conectors for psu`s i know you get 20 and 24 my mobo has a 20 pin slot and beside the cpu fan another 4, the original psu i boutght wouldnt fit the pin placement was the oposite of what i had. i want to buy something around 650 watts as only using a rubish little 400 just now but its like a jet taking off. any ideas on this. the mobo im using is a asrock dual sata 2 the one on here for intel. and my psu is some cheap thing i got from a local guy
