So I made a mistake and really do not want to rma a psu that I have for a build. It only has a 20pin and the mobo has a 24pin. Can I still use the 20pin psu ? There is plenty of power for the build ? Both from newegg:

and

Solution
20-pin omits the last four: 11, 12, 23 and 24) Color Signal Pin Pin Signal Color
Ref: http://en.wikipedia.org/wiki/ATX

Very possibly, but not recommended.
You would need to verify that with an ohm meter:
On the Motherboard, no other connects plugged in Pin 11 _> 10, Pin 12 ->1 and Pin23-> 22 read a short: Then Yes it should work, if not No workee.

Reason it is not recommended is the IR drop across the connector Pins (wires should not be a problem). If this IR drop is two high it could melt the connector plastic shell. I could give an example, but I would be pulling numbers from the end of me that sits on the Pot.
