Upgrading Video Card & PC Power Supply?

Greetings all.



I have a Dell Dimension 8400 PC - P4 3.0ghz and 3 GB RAM. It currently has a stock 350W power supply.



I am looking to purchase an EVGA GeForce 8800 GT Akimbo Superclocked video card (as listed here) http://www.newegg.com/Product/Product.as… and I obviously need a new power supply as the card's minimum requirements are 400W.



I am considering this particular power supply unit:

I know quite a bit about PC's, but power supplies are my weakness. I've never even replaced one to be honest.



Does that particular unit look like a good one to go with? If not, do you have any other recommendations?



Also, for major PC enthusiasts, any other advice about this planned upgrade would be most welcome. I can't afford to upgrade to a brand new PC just yet, but I figured this upgrade would go a long way in improving performance for newer games.



Thanks in advance!|||I actually used that power supply for a few hours, its pretty loud



you might want to check if your computer is in the ATX form factor, many dells use proprietary power supplies and connectors to the motherboard
