Corsair tx 650v2 7950 Crossfire enough?

post #1 of 6
Thread Starter 
Sorry if this is a repeat, but i'd like opinions. I'm planning for a pair of 7950s and was wondering if my power supply would be able to handle it. The PSU is about two years old. Specs should be in my sig. I tried a few different wattage calculators, and this is what they gave me. so Ideally my power supply would, be enough, but i'm still skeptical because everyone always says 750w for crossfire. Also if anyone could answer my micro stutter question that'd be great too

Assuming you're not doing any overclocking/overvolting, you should be fine.

Ok thanks, I also noticed that you have a pair of 7950s yourself. Any problems with micro stutter?

You cant do crossfire with a TX650 it only has two PCI-E cables

Only way you can do it is to use adaptors

Wattage 650 watts is enough for two 7950´s

check if you have a single rail capable of doing 600watt in your psu.
