Advice on a power supply.

[HSSL]

I have an older computer. A compaq 8000t M#P8656T. 3.2 ghz p4. P4SD-LE (Yukon) Im not ready to take the plunge yet to a newer system.
I want to install a saphire 3850 agp card and need to get a good PSU.
Recomendations would be appreciated. Would this one work?

This would do you well. Cheaper, great price, no rebate required and five year warranty.

The specs from here say that i have an ATX system.

Is that compatible to a ATX12V?
