Personally I'd pick an 850w unit if you wanted to really have a big overclock on both cards. You can have a mild one with a 750w supply.

thanks man any recommendations or should i just stick with corsair but move up to the tx 850 v2?

 

[marshallbradley]

TX 850 would be great. If you want to spend a bit more cash on a modular/gold efficiency unit the AX 850 is about $15 more: http://pcpartpicker.com/part/corsair-power-supply-cmpsu850ax

Both are great options though, just depends on budget.

thanks again, problem is i live in canada and the ax850 is like $166, while the tx850 is on sale at a local store for $115, so im going to go with the cheaper one. though if the ax850 was $135 in canada id definitely have gone for that one. idk would amazon.com charge extra for shipping to canada or would you have to make the purchase on the canadian site with the canadian prices?
