That's actually the direct descendant of the power supply in my box. Very good PS. Will probably still be good when you build your next box (if).
It is a standard ATX size (type under specifications).
Two things to note:
1. That is a Crossfire power supply. That means if you ever go dual vid card, they will need to be ATI. Here is its sister for nVidia cards (also $40 cheaper) -

can just plug the 20 and the 4 into the 24 pins (will only go one way), or you can get a connector similar to -

Anyways, that should work.
When you go to rip out the old one
make sure you note either on paper or using stickies or using a camera what cables you pull out of where. Forget one, and your machine will not work. The Dell PS's probably were custom built for your box, so it may not have extra cables; your new PS will probably have cables you won't use. Care in removing the old one is very important so you know what to plug in!
