Well you dint say what CPU your using. But as long as its not the higher end and you don't overclock. The only negative effects would be heat. It will be fine. You can run a 24 pin off of 20 pins. Just don't force it in the wrong holes

The main thing you want to avoid when only using a 20pin on a 24pin is a GPU that pulls a full 75w from the PCIe socket.

I'll only be using the onboard so I think I'm ok :)... I'll try crunching with and see how it goes... It'll only serve as a small file server anyways... :)
