650w sli ?

[GregButcher]

So hey I was wondering that would my psu be able to run dual graphics cards?

Setup

Core i5 4670k at 4.4ghz

8gigs of corsair vengeance pro 1866mhz

Gigabyte Gtx 770

Evga supernova 650g

So could this setup handle another Gtx 770? Or should I upgrade to more?

Thanks in advance!

I think a 650w Bronze or better would be capable of having a SLI configuration.

I wouldn't get a second card with a 650w psu.. it's better to have 850

750ws more then enough for sli 850w just over kill

It is possible but might be running close because you have an overclocked cpu.

So I would suggest a decent 700w bronze psu.

750W is indeed enough

Nvidia lists the 770 as requiring 230W at load (which you'll probably never hit), which is equal to 19.17 amps over the 12v rail. The EVGA 650W G (not G2) has 4 12v rails at 20amps each. So theoretically, as long as they're on their own 12v rails, it'll be okay.

However, this is kind of cutting it close, and I wouldn't recommend it. I'd say get a 750W with one big 12v rail (the Supernova G2 and the XFX BEFX are both very nice), and don't risk it.

you are on the edge, i think you risk it, dont do it

[iNothing]

Do it bro

thats not true,his pc will use under 500W with dual  770.

 

 

I would suggest a decent 700w bronze psu.

Linus used a decent bronze psu with dual gtx 780 Ti . a 780 ti uses 90W more than gtx 770 . a gold 650W psu is better that a decent bronze 700 psu

its enough,don`t need to worry.even a good 550W psu is enough

Why are you recommending Bronze units? The efficiency relates to the power drawn from the wall and lost as heat, not the power the unit can deliver.

770's use about 230W at most, so 650W could do it. 750W would give some peace of mind, and is probably a better choice since you're overclocking.

Thanks for the replies guys and so fast wow. It was more of a kong term idea since i bought a cheap mobo (msi z87-g43) tgats not even sli compatible so id need to change that as well. If i ever get there it might be more beneficial to just sell the 770 and get a next gen single card, performance might not be fully on par but, it might be a lot more cost effective than getting 3 new components including the gpu.

Thanks again fot the hel guys!

Sure 650 would do it with no PC on GPU or CPU. I suggest a power supply calc for all of this stuff.
