376477 2005-07-28 19:23:00 i just got my motherboard and case in the mail today, and while hooking up the connections i noticed that the psu has a 24 pin connector and my motherboard has a 20 pin... I wasn't sure about it so i searched a little bit and seen psu that the extra 4 pins just come off and someone said that they hooked up the 24 pin to a 20 pin motherboard without an adaptor and it worked. I just want to make sure that it'll work without an adapter because i don't want to fry my board or anything. bobnickelson (8621)
376478 2005-07-28 20:26:00 When I bought my Enermax PSU recently, it had a similar setup.
I just unclipped the 4 pins from off the side off the main connector.
The PSU also had a seperate 4 pin secondary connector specifically for the mobo.
I can't remember what the extra 4 pins are for that attach to the main connector (I think it was for the new AMD chipped motherboards??)

376479 2005-07-28 20:53:00 The 4 extra pins are 1 Ground and 1 each +12V,+5V,+3.3V. The plugs have several pins of each Voltage to cope with the expected current draw. An individual pin can only cope with about 7 Amps without heating up and melting the plug plastic. PaulD (232)

376481 2005-07-28 22:30:00 I've done it both ways round - 20pin on 24pin board. 24pin on 20 pin board. Just leave the extra 4 hanging over - they can't touch anything. Works OK. If you are worried though, get a 20 to 24 pin adapter and use that. pctek (84)
