Hello everyone and today I asked the community if my power supply can handle two 7970's and it turns out I sadly can't. So, I am asking you guys to tell me what do you think would be the best and cheapest power supply I can buy that can power 2 7970's plus the rest of my build. Thanks. *Note: No Overclocking Will Be Done*

Current PSU: http://www.tigerdirect.ca/applications/SearchTools/item...

My PC Specs:
CPU: AMD FX-8350 @ 4.0GHz
RAM: 8 GB 1600MHz
GPU: XFX Radeon HD 7970

What makes these different from my current PSU. I am getting confused because people are saying my power supply can run the two 7970's but my power supply only has three outets. Since you are a power supply master, can you please tell me what the differences are. Thanks

just an FYI
Corsair RM750 750W Power Supply Review
Quote:
The Bottom Line
Overall, Corsair has been one of the extremely solid brands we have seen and its products have developed a rabid following among enthusiasts. Certainly, a number of its power supplies have been a part of that. The Corsair RM750, however, is not one of those. Barring the fact that this unit is an outright failure as it is today, this unit was just not good compared to the competition including its own internal competition. Sure, the voltage regulation, DC Output Quality, and Transient Load Test results were in specification for the tests it would complete, but the RM750 could not pull ahead of the competition in any category or even keep up with the competition in many aspects. If we couple that with some of the unknown and/or low end component selections in this unit, we quickly can see that, even if this unit had passed all of our load tests, there simply would be no reason to buy this unit as there better options out there. If an enthusiast wants a really quiet power supply, they probably are going to want one that at least is competitive with other products not the one that is bringing up the rear. So, if users are really considering this unit it would probably behoove them to consider some of this units competitors like the Seasonic G-750 or (if they must grab a Corsair unit) the TX750M or TX750 V2 before Corsair tries to kill those lines off in favor of this newer and lesser product. While rabbits apparently don’t lay Raisinets, Corsair has sure laid a turd with the RM750 in its current form.



btw, an excellent gold 750 with 4 6+2 pin connections
