It's probably powerful enough, but do you really want to be one of the first buyers? Did you consider better PSUs like the BFG Tech EX-1200 (a lot more power on the 12V rails), a PC Power & Cooling PPCT1200ESA (single 90A 12V rail), a ENERMAX Galaxy EVO (lots of power on the 12V rails), etc.? What happens when using the Corsair?

Yeah, it should work but I am not to sure about the manufacturer.
Never heard to much about them one way or the other which makes them suspect in my book.

A better option might be the Corsair 1000HX.
At $10 less than the Chieftech after MIR, it is internally a 1500w PSU and of extremely high quality.
It will defiantly have no issues running your system.

That's why I asked what happens when using the Corsair, but the OP might be looking for a more powerful PSU for a totally different reason.

Since you'll be increasing the PSU load by over 200 watts, you should buy a more powerful PSU (a 1000 watt unit should be enough, but I wouldn't recommend the Chieftec CFT-1200G-DF).

The Corsair you currently have will do that without trying, That psu is underrated aswell with its wattage, wouldnt b suprised if it could pull out 950 ish watt

So imo keep that Psu, but if you want to replace it for any reason (wattage shouldnt be one) like modulair? go for the Corsair 1000HX

I vote NO.
The Corsair 1000HX has the same internals design as the Thermaltake 1500w.
It is, in fact, of higher quality inside as it uses all solid caps.
As the Corsair 1000HX costs more than $100 less and has better internals than the Thermaltake 1200w (or 1500w for that matter), I still highly recommend it for the job.
