Which Power Supply will suite me best?

[Drewb243]

I have a homebuilt that I just bought off craigslist. It currently has a Kentek KTPS-750W. Just looking to get rid of this cheapo PSU and get something more efficient and a better build quality. Would take a downgrade in Watts if I could handle it.

In my rig:
-AMD Athlon FX-4100
-MSI 990FXA-GD65
-Sapphire ATI Radeon 5770 1GB
-8GB Gskill Sniper Series DDR3 1866
-1TB WD 7,200rpm
-1TB Seagate 7,200rpm
-Has a big Zalman aftermarket heatsink on it.
-Also has 7 blue LED case fans.

I may upgrade the video card to a 6950 or 7770. So add in a video card upgrade that is most likely to happen.
Looking for something that is atleast 80+ silver certified.

Seasonic SS-560KM $134 this meet your definition and it's all you'll need but it's pretty expensive. I'd lower your bar a bit and get CORSAIR Builder Series CX600 $70 (for the 6950) you can save $10 and get the 500W for the 7770 if you go that route.

So with the upgrade to a 6950 all I will need is a 600W?

You'll need 40A on the 12V line. You can get that with the 600W that I linked or the 560W. Wattage really is meaningless.

a good 500-600 watt will do. Corsair, Seasonic, Silverstone, Antec, XFX, PC Power and Cooling.

Why the Silver need? 80+ or Bronze is usually good enough. the energy saved over the life of the PSU from 80+ to silver probably won't pay for the increase in price unless it's on 24/7/365

will this corsair http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&AID=10446076&PID=4176827&SID=h4ecn1fs0ezr. Run my 5770 now and when i upgrade to the 6950 or 7770 that as well?

Would this 520W Seasonic be enough? If so I will be going with this Seasonic if it can handle my 5770 currently and the upgrade in video cards. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093

Thanks for everyone's help! Just need this last post answered.

Buy Corsair AX 750 (850, if you can afford it) and you, pretty much, can forget about buying other PSUs in at least 5+ years to come.
My personal recommendation (look at my builds in my "Profile", to get the better picture).
