Upgrading PSU

Hi, I have just purchased a 7900 gt 512mb card and need to upgrade my power supply. I am quite low on cash and am wondering which brands would be the best quality for low price. I am wanting more than just the minimum requirements as I may decide to overclock it somewhat, depending on how well it runs at stock. Greatly appreciate any help you can give me.

 

The best source I have is here;

Top end PSU's and some at reasonable prices.

This should take you right to the power supplies section with 401w-450w power supplies listed from lowest price to highest price. You can get a bigger psu, but a 450w should be good for your card. Don't forget to read the reviews on them so you can tell if they're good or crap. Hope this helps!

 

Thanks for the help guys, hopefully the one I chose will be reliable!
