Well, if you're referring to the HP systems, not just any generic i7 capable motherboard, then you may be out of luck.
Most HP computers that I've run into are already using so-called "efficient" power supplies.
Refer to http://www.hp.com/sbso/solutions/pc_...ng/80plus.html
I like to use the Logisys 480W to 550W power supplies from Geeks.com
See those at http://www.geeks.com/products.asp?cat=PWR
These are quiet, and don't get overly hot, which does lead to the assumption that power is not being wasted. (Albeit admittedly a non-scientific conclusion.) It's not a room-heating wind tunnel, I can say that. It's just a standard modern ATX power supply, for pretty much any system. I did notice my power bill went down after tossing some older hardware.
