Hi Have recently finished building P4 using a Asus P5P800 board with a 3.00Ghz processor board has a 24 pin socket manual says its ok to use 20 pin connecter providing psu can deliver 8A on the +12V and 1A on the +5V standby lead which it dos .Is there any advantages having a psu with a24 pin conector my psu is a bit of a cheapie (I know not a good idea) psu is a 400w psu thanks in advance Brian
