Will my PSU be sufficient if I add another 6670?

post #1 of 4
Thread Starter 
In my rig I have a 650w psu and I'm using a XFX 6670. I want to pick up another one and crossfire them but idk if my psu will be enough. I dont have much in my rig but I just need an experienced opinion.
Thanks in advance!

It's easily enough, even if it's a bad PSU. The 6670 won't use more than 90W under full FurMark load, so as long as you have the required power connectors you'll be fine smile.gif

You even have enough power for quad 6670's, if only they were capable of it.
