Can u guys help me choose on which is the best to buy?

Thanx

 

is there a reason that you need a 1000watt psu? unless you have quad sli and quad core you wont need anywhere near that much power. i would recommend this corsair psu.

what parts are you buying?

 

cause i'll have 2 9800 GTX OCX, quad core, later a physics card, sound card, drives, hard drives etc

 

a 750watt will be enough for those parts and also physics cards are not that useful. so don't waste your money on one. i found some power consumption charts for sli 9800.

So i should be perfectly ok with an 850W power supply?? but which one should i buy out of those 4 brands??

btw thanx for the charts

 

the psu i recommended in my first post.

The Corsair 750W TX will be more than sufficient as long as you're using two GTXes. If you're using two GX2s for Quad SLI, you should consider http://www.newegg.com/Product/Product.aspx?Item=N82E16817139007&Tpk=CMPSU-1000HX but ONLY if you're using GX2s. For the GTXes the 750W TX will be ample.
