Hello, im building my first SLi system soon and i was wondering if a 20+4 pin power connector will work in a mobo with a 24 pin connector?
Just for reference the PSU im thinking of useing is:

and the mobo is:

Also if anyone has any Suggestions for better PSU's or Mobo's im open, however i must have at least 2 extra PCI slots because im still stuck in the dialup age :( .
Thanks for all your help!

First of all: GEEZ that's a monster of a PSU. Not 2, not 3, but 4, yes FOUR 12V lines! 700 Watts! $170! You must be crazy...

But yes, a 20+4 mobo pin will work in a 20-pin mobo. There are 20 pins on the main connecter, and another 4 that can be clipped onto the main 20 in case you have a 24-pin mobo, thus making it 20+4.

No prob.

Pretty much all modern (note keyword, modern, as in within the past 2-3 years) PSUs will connect to your motherboard, no matter what type of connection. For example:

20+4 pin PSU on 24-pin mobo: Clip on the extra 4 pins
24 Pin PSU on a 20-pin mobo: Use the 24-to-20 pin converter that is included

And of course the other 2 combinations, 20 to 20 and 24 to 24 which will of course work.
