Hey Forum,

Does anyone know how much power two GTX 1080's use while gaming in SLI? I presently have a 650W power supply and my second 1080 is on its way. Do we think that will suffice? I think it will work but just on the edge and definitely not "Efficient" but if it work it works...

 

Thanks

650W is enough for two in SLI provided you don't overclock. However, if it were my system I'd use a 750W PSU.

|PSU Tier List /80 Plus Efficiency| PSU stuff if you need it.

360W stock

400-420W OC (depends on silicon)

 

As long as you don't have a CPU that takes much power (OC 6700K are fine, OC X99 or FX-8350 are not), you're fine on 650W to even OC the cards.

We have a NEW and GLORIOUSER-ER-ER PSU Tier List Now. (dammit @LukeSavenije stop coming up with new ones)

You can check out the old one that gave joy to so many across the land here

 Yeah, no overclocking, on top of the founders ed clock. And a 6700 non K. 

Thanks.
