Although you should be pretty close with the 850W you have do a check on there site with the calculator

where is the calculator

Man you're fine with your current PSU.

I would also say you are fine with your current PSU as well, though not much headroom. However a Corsair HX1000 certainly cant hurt. Its better then that Chieftec unit by leaps and bounds.

The calculator is found here: http://extreme.outervision.com/psucalculatorlite.jsp

+1 +1 +1

I second that motion. Those vid cards pull around 200w under MAX load and your cpu maybe 150w. Unless you're folding on those 260s and i7, I see no reason to upgrade.

Edit: looks like I took to long to post. I 4th that motion...

You are fine with that 850 Corsair, its one hell of a good PSU.

what if i go for 3 x gtx 280......will my tx-850 work on that

 

[gigabit]

I would have to say yeah i have the TX and HX 850's and both are great.The TX at one time was running a Q9650 at 4.2ghz and 5 xHD's all in raid 0 + two GTX 260's core 216's in SLI and two DVD +RW's and a usb zip drive and a few other odds and ends and 7x120x25mm fans.And the system was dead stable

 

[kayawish]

[EarthDog]

I say you dont need anywhere near that. Corsair 1000HX will do just fine.

 

[nzaneb]

This runs my I7 and 3 x 285's, Full load 24/7 http://www.newegg.com/Product/Product.aspx?Item=N82E16817194039

The Corsair 850TX runs my Q6600 and 3 x 260's, Full load 24/7 just fine.
