Wattage requirement for 6870's in Crossfire X?

post #1 of 7
Thread Starter 
My 700W Xion PowerReal is a really bad PSU. I saw a Corsair enthusiast series 650W PSU and I was wondering if 650W is enough for 6870's in Crossfire X.

I only have one right now but I am getting another 6870 in the future.

Is the Wattage enough? And as always, I am open to suggestions, but I will not be spending over $100 on a PSU.

I can't link the one I was talking about since I am on my phone.

Also, I don't know much about PSU's, but my rig is in my sig. I also have 7 case fans if that matters.

You'll want at least a quality 550 watt PSU for CF 6850's and a 125w processor.
The corsair would be a good choice.

I'm not sure about my CPU but it is a 965 BE.

I am on air cooling only. Only my Sig rig stuff. I hate my phones autocorrect... Turns "Sig rig" into Sausage.

Then for your Sausage machine, a 550-650 is ideal from a quality PS. I regret getting my crap 1000W PS... oh the days of ignorance.
