Can this PSU run two GTX 760's?

It should be fine. What are your system specs?

 

[Kekoh]

That PSU could handle a three-way SLI. So yeah, you will be fine for two 760's.

I haven't bought everything yet but that's the build I'm looking at so far.

I'm a little concerned about the quality of the PSU. Some people say it's great, others say it's cheap.

Yea its a pretty cheap quality PSU... You really only need like a 650-750w PSU for SLI 760's... I'd get a high quality 750w PSU over that Roswell one.
Maybe something like this : http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010

If you are concerned about the quality, then don't go for one of the cheaper PSU's. You get what you pay for.

If you want a high quality PSU, you will have to pay more. Something like the Corsair HX850. It's a little bit more expensive but you won't have to worry about the quality of it. You also won't need more than 850W for a SLI setup, unless you plan on 3-way SLI at some point.

HX750 would also work, but people often like to leave extra power available, so the PSU functions more efficiently. I have the HX750 myself and it is a great PSU and extremely quiet.

750w is already overkill, a 650w quality psu would be plenty. I think the 750w is the way to go though. At normal gaming usage the psu will be at about 40-60% load (most efficient load for most PSUs).

those units are made by sirtec. I would find a better PSU

something from this list is always safe and all in the right price range with great warranties:

I would not recommend a 650W PSU. A 700W minimum is recommended (not required) for SLI 760's.

shows full system peak watts to be 449 FROM THE WALL... So if they used a 80% effecency PSU that means the psu was supplying 359.2 watts to the computer... meaning a 80% effeciency 650w PSU would be at 55.3% load.

And that was done with a Core i7 3960X overclocked to 4.6 GHz so most likely his system will use even less than that.

Those minimum requirements on the psu for card setups normally are way over what is really needed due to the fact they have to take into consideration for all the very low quality PSUs out there... But if you get a high quality PSU you can go with a much lower wattage.

I run a 750 watt antec. I run two 7950's overclocked to 1200MHz. Also an overclocked ram and CPU ie. i5 2500k at 4.8 GHz. I think you would be fine with a 650 (nvidia recomends a 500 watt system allowance and 170 per additional GPU).

700 is just right and 750 gives you headroom for anything else.

If you buy quality then you will get above the wattage rating. my antec 750 puts out 850 when pushed (according to hardOCP).

I would get the best xfx or seasonic you can afford. screw the bronze or gold rating get the watts instead. you only really care about wattage and the consistency of that 12v rail (the 3 and 5 matter also).

Thanks for the info. I pulled the 700W recommendation from a third-party site, not directly from Nvidia's recommendations. I guess they pretty much followed Nvidia's lead on that.

 

[prunehairs]

I'm probably going to go with an XFX 750w if that can SLI. Thanks for all the feedback!

 

[prunehairs]

What do you guys think of this one? http://www.ncixus.com/products/?usaffiliateid=1000031504&sku=78946&vpn=P1%2D750B%2DBEFX&manufacture=XFX&promoid=1320

Trying to stay in the $100 range.
