I am just wondering if two EVGA GeForce GTX 760 2GB Video Card can be used with the power supply either 750w or 850w?

I picked either one of these power supplies and then the sale person at fry told me that because of these two graphic cards or running SLI, either 750w or 850w is not enough for this setup and then he said if I use these power supplies, the graphic cards will get burned or they don't supply enough power. Then he took out the 1200w one and said this one is the right one, no 750w or 850w.

My question is whether I really need 1200w for EVGA GeForce GTX 760 2GB Video Card running in SLI? Or 750w or 850w is really not enough for this graphic card running SLI? I really need some professional advice and I really appreciate your help in advance.

That sounds like Fry's, 750 would be plenty for sli depending how much else you have in the rig, even so 850 would be a little much as well. They "recommend" you use alot more wattage than needed. My 7750 needs 500, but really can run on a 300 watt. Frys tried to sell me an AX1200 watt for my rig in the signature. I just looked at the guy and said, nevermind Ill do it my self considering I built it.

750-800 watt will be fine 1200 is way overkill sounds like he is trying to get you to spend more money

The GTX 760 has a TDP of 170W. Tom's Hardware measured a peak power consumption of 160W in their review of it, but let's say 170W to be on the safe side. Two of those would then draw a maximum of 340W. If you've got an Intel CPU, it most likely draws less than 100W. Add in the minor power draw for memory, motherboard, fans etc. and the system could draw more than 500W under heavy load, but not more than 600W. And certainly not more than 750W, let alone 850W.

With an AMD CPU you could see another 50-100W power consumption in the worst case scenario. Even then, a 1200W power supply would be ludicrous overkill.

A good 750w PSU would be more than enough.

Well...That is what I thought. Because according to the description of the package, it is said that a single graphic card of EVGA GeForce GTX 760 2GB Video Card requires at least 500 watt, that's the reason why he might think it this way. I would definitely trust you guys as you guys have more experience.

BTW...Here is my build

CPU: Intel Core i7-4770K
Heatsink: COOLER MASTER Hyper 212 Plus RR-B10-212P-G1
Graphic Card: EVGA GeForce GTX760 x 2 (SLI)
Board: MSI Motherboards Z87 MPOWER
Case: COOLER MASTER CM Storm Series Trooper
Power Supply: Rosewill 750W 80 PLUS GOLD Certified Power Supply CAPSTONE-750-M (Fry sold the 1200w for dual EVGA GeForce GTX 760 2GB Video Card)

The build hasn't included any harddrive or anything. Just wonder what memory modules are good for this build?

Best solution

Fry guy needs to look at nVidia web site

Thermal and Power Specs:
97 C - Maximum GPU Temperature (in C)
170 W - Graphics Card Power (W)
500 W - Minimum Recommended System Power (W)
Two 6-pinSupplementary Power Connectors


500 watts for system + 1 card ..... 170 watts for 2nd.... that's 670....add some cushion if OCing

Here is Guru3Ds power supply recommendation:

GeForce GTX 760 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 760 SLI - On your average system the card requires you to have a 700 Watt power supply unit.

If you are going to overclock GPU or processor, then we do recommend you purchase something with a bit more stamina.

Thanks so much but would you guys care to recommend which memory stick to buy? I would prefer 16G for dual channels.

I limit my purchases to hi performance lines from Mushkin (Redline) and Corsair (Vengeance)

DDR3-1866 CAS 9 are quite affordable
$134 http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$149 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

DDR3-2133 CAS 9 are quite affordable
$160 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

DDR3-2133 CAS 11 lil more
$169 http://www.newegg.com/Product/Product.aspx?Item=N82E168...


what's faster ?
9/1866 x 1000 = 4.82 nanseconds
9/2133 x 100 = 4.22
11/2133 x 1000 = 5.16

No need for 16 gb of memory either 8 gb is more then enough i think its a waste of money going anymore then 8

Get the Antec 850W HCP Platinum 80 Plus Power Supply Unit. Check the review out here:
http://www.guru3d.com/articles_pages/antec_850w_hcp_pla...


The best power supply in the 850W category priced at $ 249 on newsegg. It delivers 94% efficiency which saves a lot of dollars at the year's end and also it should easily take care of two GTX 660s. This Power Supply Unit also makes room for Future upgrades.

No use getting a 1300 W or 2000 W even if it doesn't have efficiency. Moreover the Antec 850W HCP Platinum Edition is 80 Plus Platinum certified with an Industry best efficiency of 94%. That is gona save him more when it comes to consuming electricity. Moreover it comes with a 7 year warranty. What beats that?

Well, the 850 W which I recommended has a unique feature of consuming less than 0.5 watts of power at Idle. That is something which is amazing. Mostly other good PSUs idle around 10-30W. It's better you check the review out of which I already gave a link earlier.
