Nope, 850W is the minimum, and 1000W would be recommended.

I wouldn't use either one of those(both have quality issues), let alone use them in a SLI setup.
Here's some better options

or for alot of extra headroom that approaches overkill

Those are both solid PSUs. They won't leave a lot of headroom for overclocking though.

GTX 780 SLI - Peak wattage 544W/46 amps.

If your not heavily overclocking or using souped up 780 variants, 750W would be sufficient. But for around the same price as the RM 750, you may as well get 850W for similar money & better quality.

This PSU uses the same Seasonic platform used in the Seasonic-X series & Corsair AX.

Read the review then purchase ^

9.9 out of 10 from jonnyguru.


Performance (40% of the final score) - we're down to scoring time again. And, as with all other recent units from EVGA and Super Flower, this one will be a breeze to score. Pass for Gold, both cold and hot, means no points removed from a perfect score. Amazing ripple suppression the likes of which has only been seen a handful of times on this site means no points removed there. And finally, yes, this unit did manage to hold onto an average of 1.2% regulation in the hot box so no points come off there, either. This guy's getting a 10.

Functionality (20% of the final score) - full modularity. Lots of cables. Good cable lengths. Plenty of connectors. Switchable semi-fanless mode. Lots of goodies in the box. Nice size 16 gauge line cord. I really can't think of anything to complain about here, either. 10.

Value (20% of the final score) - $144.99 is the asking price of these at Newegg right about now. It shares this price with the Silverstone ST85F-GS. Now, about the only thing that unit has on this one is its much shallower depth. Other competition? What other competition? Coolmax? More money, if you can believe that. Corsair HX850? More money. Corsair RM850? More money. Themaltake Toughpower Grand? More money. Seasonic X-850 KM3? Way more money. EVGA has this category locked right down. 10.

Build Quality (20% of the final score) - I'm going to remove a point for the fan control wiring and be done with it on this one. Soldering is good enough to pass with no deductions, the AC line filter is pretty much all there in the end, the component selections are fantastic, and the capacitors are wall to wall Japanese. 9.5.
