GTX770's in SLI, 660W sufficient?

post #1 of 6
Thread Starter 
Considering running GTX770's in SLI. I currently have the Seasonic X-660 power supply. I assume this will be sufficient?

Thanks

Yep.

Ran a GTX 690 ~1200MHz with a 3970x @5.3GHz for many bench sessions on my AX650. Never a shut down or problem.

yes.

guru 3d saw ~400 watts for a 770 SLI set up (just the cards.)
http://www.guru3d.com/articles_pages/geforce_gtx_770_sli_review,4.html

[H]ardocp pulled 53 of the 54 amps for the 12 volt rail for that PSU. (636 watts)

yea doesn't the 690 pull less watts than 680SLI @2x195watts....aren't 770s in the 250watt range?

162w average and 180w peak during Crysis 2.
Furmark power draw is 214w - a scenario that doesn't happen in a typical workload.

This was measure at the GPU, rather than the entire PC from the wall. So values from the other components and efficiency doesn't play a role, giving you the lowest margin of error.

The Seasonic X660 is plenty.

770s are in the 230w range as per Nvidias site:

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications

A 3770k will use about 125w with a good overclock.


My point I was just trying to get across is a GTX 690 @1200MHz and a couple of GTX 770s at the same clocks would use the same amount of juice in general.

Half of my post was about my 3970x @5.3GHz using near 1.7v. Looking around, that would eat roughly 300w by itself to the OP's 125w cpu.

Here is the actual bench I was referring to:



This was done on my AX650, thing is a beast!tongue.gif


The only problem for the OP is if he gets a couple of unlocked voltage 770s(Lightning for eg.) that can push 1.3v or there more, then I think the X-660 wouldn't be enough.
