What power supply to buy

[fox101]

Hello,
Q6600 2.4ghz
Nforce 790i
Sli Gtx 280
My power supply recently died on me and im going to order a replacement, trying to decide between the Corsair -AX850, the 850HX or the 1050HX, iv read reviews and specs for each but im still on the fence as to which one I should get, the 850HX is the cheapest and the AX850 and 1050HX are the same price. Occasionally use the comp for gaming, want to have the option for upgrading/using the power supply in a future comp.

The HX850 should be more than enough. I have it myself powering an i5-2500K OC to 4.5MHz & 2x6950. In fact I ran the 2x6950 with an unlocked 720BE on a Corsair HX620.

Do not worry about getting higher power supply because the current & future generation of graphics cards are getting more power efficient. If budget is not the matter, go ahead with the HX850 ( it feels good having it in my rig ) but if you want to be prudent & go for what is essential (without losing what you want from the HX850 in the first place), you can get the HX750 and save $30.
