HI all i need to buy a PSU widin 2-3days. My specs are :

Phenom2 955BE
Sapphire 6850
1 7200rpm HDD
3USB devices preferably

Ok so my question is how much watts and 12V amps do i really need. And also please suggest some good PSUs. The available ones where i live are:

CoolerMaster ExtremePowerPlus 400,500,600
CoolerMaster GX450
Tagan Stonerock 500watt 600 max
Corsair builder CX400,500,600
FSP bluestorm 500
Seasonic 420,520
Gigabyte 550P
Antec VP450
Iball splinter 500,600

Others are either unavailable(Kolkata,India) or out of my budget (~3.7k).
Thanks in advance :)

SeaSonic S12II 520 -best choice.
CoolerMaster GX450 - good.
Both are 80+ Bronze and carry 5yr warranties.

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

Avoid the Cooler Master eXtreme Power Plus series, they're awful.

I would also recommend that you avoid the Tagan Stonerock, Gigabyte 550P and Iball splinter.

Of those you listed, Seasonic > Corsair > Antec.
The CM GX-450 is one of their few that are ok: http://www.hardwaresecrets.com/article/Cooler-Master-GX... but many of their others have liar labels or claim protections that are missing (and/or are lousy quality); that's dishonest, so they don't deserve anyone's business. The Antec VP450 received an excellent competent technical review: http://www.hardwaresecrets.com/article/Antec-VP450-Powe... so if that's the one that fits most comfortably in your budget, it will do nicely.

Edit: The Corsair CX are fine. The CM "Extreme Power Plus" don't come close on any measure.

Newegg and tigerdirect are oldies but goodies for the system builder. Im a fan of Thermaltake and Enermax power suplies and they may be out of your price range but as I always say, price is not an object when picking the component that can do the most damage if it fails.

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

The VP Series 450 watts (VP450), with its combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connector, is sufficient to power your system configuration with a single Radeon HD 6850.

The Seasonic S12II-430 Bronze (SS-430GB), with its combined +12 Volt continuous current rating of 30 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single Radeon HD 6850.

The Seasonic S12II-430 Bronze is better than the Antec VP450.

If you're planning on overclocking the CPU and/or GPU then I would recommend that you get a little more capacity like what the Seasonic S12II-520 Bronze (SS-520GB) has.
