7970/280x cf

Mclegendary · April 12, 2014

I am going to be building a new rig. I will start with only a single card, but I may add a second card down the line. Will an rm750 be enough for 7970/280x crossfire. My cpu will be an 8320 or 8350 which I may overvolt to as high as 1.5v.

Yes, it should be able to be powered by a 750Watt PSU.

I would get a 850w psu just for the extra headroom. It should be fine with a 750w psu but if you're going to heavely overklock I would advise you to get a 850w psu.

I've decided to get the rm650 and buy a new psu when the time comes for Crossfire. Thanks for the help.

If you are in the US, both of the EVGA Supernova 750/850w PSU is in the same price range as the RM750/850, and there's a $10 rebate going on that effectively made it cheaper. It's, the EVGA, is a higher quality, better performing unit that offer a 10 year warranty. I would suggest that over what you are looking at.

If you have a definite plan to CFX, then buy the higher wattage unit now. You are going to spend more as you have to buy the PSU twice and selling the first unit at a lost.
