A suitable power supply

I was wondering since I will be purchasing a GTX280 what kind of power supply do I need and how many Watts it requires so it can run smoothly without any bottlenecking.

Plus, what do you think of the Epsilon brand, because they sell them cheap where I live (Not in the United States).

Thank you for your help.

id suggest a 850 watt.

Ive never used that brand, and its a tad overkill. But im futureproofing you aswell. This is incase you choose sli, or a future gpu upgrade is more power demanding.

i really doubt gpus in the future will need a 850w power supply look at processors they get better and more energy eficent

gpu's are different, their power usage only grows. And its just what i recommend, its what i would get.

yah but you realize to have a power supply like that it will cost about $150 a year to run

About future-proofing, I don't think that I will be upgrading from a GTX280 any time soon (or even get another one for SLI). All I need is a good one now. My friends recommended a 600W power supply and said that it would be enough to run the card without bottlenecking. All I'm doing here is to ask if you guys share the same opinion and if Epsilon is a good brand for a power supply. samidiab
