Can i use 700watt for SLi 770?

Daavtec · Jun 8, 2014

Is 700 watt enough for sli 770? I have this psu already so don't say safe money and buy this or that... i got everything already. But i'm afraid that it won't be enough. I do not OC these cards but my cpu is OC to 4.4ghz (fx 8350) GPU's are evga gtx 770 2gb superclocked acx coolers(if im not wrong) Thanks alot!!

It's recommend to use a 1000W PSU for SLI. For a more stable system.

What is the make and model of the PSU?

Mr_inflexible · Jun 8, 2014

Suztera :

Or Corsair.

750-850W is enough for GTX 770 SLI including overclocking headroom.
Make sure you have a quality unit like Seasonic or XFX.
What psu do you have?

juanjovargas · Jun 8, 2014

We need to know every component to know it, but I think it is enough, because both cards require 450W only for themselves. You can put your components in that form:

I would say it wont work, especially if you have an older model psu. That system will need ATLEAST 750w, but as suggested, 850w-1000w is an optimal range to avoid overheating or loud psu.

No you want at least a top tier 750w.

850w recommended.

Mr_inflexible · Jun 8, 2014

Where does it say this?

Dark Lord of Tech · Jun 8, 2014

850W is more than enough for 2 - 770's.

Mr_inflexible · Jun 8, 2014

Its not recommend though.

Dark Lord of Tech · Jun 8, 2014

Best 850 watt on the market.

This is my system, i wonder..

You need more power and that's not a good PSU.

Here is Guru3D's power supply recommendation:

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2x SLI - On your average system the cards require you to have a 700~800 Watt power supply unit as minimum.

^^(Off topic: Is everyone seeing that up-vote count as 0?)^^

Dark Lord of Tech · Jun 8, 2014

Yes you are correct.

17seconds · Jun 8, 2014

I just up voted Blackbird with no problems.

Daavtec · Jun 8, 2014

So i can't do it right now if i'm right untill i got alteast 750watt am i correct?

Dark Lord of Tech · Jun 8, 2014

I would get a decent 750w , YES.

Then proceed.

Eduello · Jun 8, 2014

17seconds :

Yeah, the issue is that I already voted up the answer I quoted, but the vote count is 0 and it won't let me vote it up again. Oh well, at least the notifications and PMs are working with the new server...

And yes, a decent 750W should do IMHO as well.

Can i use 700watt for SLi 770?
