I know the answer is probably a resounding YES, but I just wanted to double check. I just purchased a new chassis for my PC and now my 4pin cpu power plug doesn't reach. I'm wondering if the 4 pins are required for operation, or can I get by for the weekend without it until I can go get an extension?

EDIT:

Looks like it is mandatory with my Mobo. I tried to post without it and i just got a blank screen. Looks like I'm getting a new adapter asap.
