Hey friends,
I'm going to buy a single 6850 instead of 6950 because next gen gpu is near if they didn't provide significant improvement then i will crossfire. So i need a futureproof PSU that can handle 6850 CF (OCed) with i5 2500K (above 4.5ghz).


PSU In my Mind:

Corsair GS600
Tacens Supero 600W
Seasonic 620W PowerSupply (S12II-620)
Seasonic SS 500-ES 500W PSU
Tagan 500W

Gs 600 is best among all mentioned. But since you are doing a extreme OC you might need to up your budget :wink:

Since you will OC all your CF Graphic cards with a huge OC on your Processor already I would say a SeaSonic SS-850AT @Rs.6300 might be needed. Again it may be too much power for your rig. But I think worth the Investment just as a "insurance" to your costly hardware :)

What is the current price of TX650 V2 ? You really want to kill my budget. :grin:

@ 6K i can get Glacialtech 950W it's modular & better than corsair 950 TX V2. Any other alternative at 5K price range ?

Actually many of Corsair PSU are manufactured by Seasonic. So, it performs same as TX750V2.

Tacens Supero 600W
Seasonic 620W PowerSupply (S12II-620)
Seasonic SS 500-ES 500W PSU
Tagan 500W
Out of the listed, Seasonic S12II 620w is the best. Corsair TX650v2 is manufactured by Seasonic and it is the same S12II 620w model. Better get 750w just for an extra buffer. 650w is enough for HD 6850 CF though.

Thanks ICO I will try to get 750W Seasonic. I think you can close the thread now.

A dumb will only buy gs800 at that price. (no offence). Why will anyone buy gs800 at 5.7 when he can get GlacialTech Modular 950 80+Silver (Performed like 80 Plus Gold ;) ) or Corsair TX750 V2 or Seasonic 850W @ 6k? GS800.

^^ nvm, I wasn't suggesting him GS800, but informing him about the price of GS800, which he asked in the post before mine.
I don't know anything about the performance of GlacialTech Modular 950W PSU, but TX750 V2 or Seasonic850W is lot better than GS800. :thumbs:
