What Power Supply will work with GeForce GTX and my AMD 64 x2?

[StefanSchultze]

Could you help me with advice?
I bought the following PC.

Now I want to add a GeForce GTX card

I do realize that I will need a larger power supply than the 250 W my new PC comes with.
It says 475 W in the spec for the graphic card. When I research power supplies it gives me
models starting on from 19.95 Dollars with 480 W already for that price.

How do I know which ones will work fine with my computer for the lowest price? When you look
at the graphic card link they recommend one with 800 W but it cost over 100 Dollar extra.

Would really appreciate your advise.

this psu will do just fine for ur pc.. try looking somewhere else if u have a good deal(like rebate or off) around for this one..brand 500watt is enough for ur pc (like antec, seasonic, corsair)
