My current system is

Intel E6750 2.66 (Stock)
Asus P5K-VM Mobo
Samsung 320GB SATA2 HDD
2x1GB DDR2 800 RAM
20" Asus LCD Widescreen Monitor

I will never overclock and I like to keep my system as light as possible and I wont have SLI. I plan to purchase a card similar to GTX260 or whatever cards come out in the next few months from Nvidia. Any suggestions what kind of powersupply I should get now for a setup like this and gfx card like 260 which i plan to buy in the future. I am thinking future proof...but that doesnt mean i'd like a 850w psu. I am thinking whatever is just perfect, not to less n not too much.

Using this calculator
http://extreme.outervision.com/PSUEngine
your system with the GTX260 will use about 300w (that's bumping you to 4 sticks of RAM, 4 120mm fans etc.), PSU manufacturers recommend running at 60% of load. Any good quality 500w to 550w power supply would be fine.
EVGA recommends 500w and 36 amps

I'm running into price problems at Newegg, that PSU should be $79.99 after rebate.
Check www.buy.com they usually have better prices on Corsair PSUs and free shipping
Here for how many watts the GTX 260 uses

Wow, thanks...the tool helped. If wat it says is an approximate wattage requirement then i can decide wat to buy.

Also another question, I hear that wen buying a psu u need to check the ampere of 12v rails or something. I am totally clueless abt this segment. Any idea?

He already mentioned the amps. And that the Corsair units from buy.com are basically the best for your dollar.

Just buy this Corsair and be done with it. It will reliably power any single video card for $75

a nice corsair 550 would run it , but go 650 for some extra room for the future :)
