Is it possible to use a 20 pin connector on a motherboard that has 24 pins?

Maybe... if the remaining 4 pins is the place where the additional 12V cable should be placed.
About which motherboard are we talking?

Its a Compaq Presario 5330us. The stock motherboard for that brand. There is a separate 4 pin connecter for the 12v.

Compaq seems to be using different PSU then the standard ATX ones so I don't think it is possible.

I was curious because I had found this post on another website:
"Use 20 Pin ATX Power Supply on MB Requires 24 Pin

Is that possible?

Yes. As long as pin 1 on the 20 pin power connector align up with the pin 1 on motherboard 24 pin power connector. Same apply to the ATX12V AUX connector, as long as its pin 1 on the four pin connector align with the pin 1 on the six pin connector on the motherboard, they should work."

I ordered an Enermax 365p-ve fca PSU and didn't bother checking my motherboard first (oops!) and I think that this PSU has a 20 pin connector.

Well I don't have experience with using a 24 pins motherboard with a normal ATX (20 pins) PSU. But if you can tell me which pin has which function (ie Pin1: PowerGood, Pin2: 5V or something) I can check if the pin lay-out is similair.
