So bascically I am replacing my PSU so that my computer can properly hold a Radeon 6850 card. My question is, what wattage should I get? Apparently AMD says a 500w PSU is required, but TigerDirect is saying 550w. I was thinking of buying a 600w PSU to be safe, but is that overkill? Here are my specs:

AMD Phenom II x4 945 3.00Ghz

8GB of DDR2 RAM

1 TB HDDD

1 DVD-RW

Windows 7-64 bit

my mobo(if u need to see it) http://www.newegg.com/Product/Product.aspx?Item=N82E168...

(XFX Radeon 6850 1GB 256-bit)

PSU???

Here are the 2 PSU's I was thinking of getting:
http://www.newegg.com/Product/Product.aspx?Item=N82E168... 550w

http://www.tigerdirect.com/applications/SearchTools/ite... 600w

If you could help me figure out which way to go, or suggest a better PSU for the same price, I'd appreciate it. Thanks

I would get a Corshair http://www.corsair.com/psufinder/ better slightly oversize the wattage as they lose a minimal percentage of power over time (years). The corshair also have overvoltage and undervoltage protection, especially the enthusiast series, that usually prevents the psu blowing the motherboard and components which is always a bonus.

The wattage difference is likely due to wether or not it is an overclocked card or not. Also, that number is padded, so if you are not OCing to the moon then the 550W is probably fine (unless you need a 2nd card).
