DFI LP Ultra D Do I need a new PSU

I am upgrading my systerm from a Socket A to a socket 939. I now have a DFI LP Ultra-D. I have a Sparkle 400 Watt ATX powersupply. The ATX is only 20 pins... looks like the DFI needs a 24 pin one. I need a new powersupply eh? I think so but I want to come on here to make sure before I buy one. Sucks I didnt even think about needing a new PSU.

Is there really a need for two?

Edit: Just realised this was posted BEFORE the other one buy 2 minutes. Either way, don't need to double post, one should do the job guy.

No not really needed but I needed an answer quickly and figured I might not get as good an answer in the PSU forum since there may not be as many people there who are familiar with the DFI board. Anyway what are you worried about if there are two posts I was just trying to cover all the bases dont trip.

Anyway thanks for your help in the other post. I know what I need to do now.
