[hotcoolfool11]

Hey guys

 

I want to SLI my 1080 but i want to know if my EVGA Supernova 650 G1 can handle it.

 

Here's my PC specs:

i7-6700K at 4.6Mhz

MSI GAMING M5 Z170

16GB of Kingston HyperX ram

MSI SEA Hawk X 1080

EVGA SuperNOVA 650 G1

 

Thanks in advance!

Get a 1080ti instead SLI is super unoptimized today

750W would have been ideal, but it should still work.

nope, OP should be fine, SLI has come a long way, no problem so far with my 1070 sli.

as long as you keep running your CPU at 4.6 MHz you can take it out of the equation - then you get liek free 140W

 

I mean if you don't overclock you'll be fine with what you've got, but  750 would be better for some nice tasty overclocking

Some people said it's unoptimized

those people haven't used SLI, as i said SLI has come a long way from GTX 480 days.

No that's over a 4 CPU power and a 6700k is rated for 95 watts and it's volts that heat up not GHz

It's a bit closer than I'd say is ideal but should be fine. If it's not then your PC will just shut down and you'll have to get a better PSU so shouldn't do any damage even if it is an issue.

I had GTX 970 SLI and it was trash on some games but great on others

it will depend on the games you play, i haven't encountered any problem with mine. also, i wouldn't SLI 970s, misleading marketing with 3.5 gb vram is not enough for the extra performance you get.

Yeah, no. 650W is more than enough, but you have an EVGA NEX-G - a fairly mediocre supply.

I'd recommend you replace that with an EVGA G2/G3, Corsair RMx/RMi, Bitfenix Whisper or something similar classed to them.

Your PSU isn't great but 650W is the borderline minimum and should be fine.

364W for two bone stock 1080s in SLI alone. Factor in something like a 7700K (add 150W for safety) and you're still under 650W. Just don't OC much, if at all, and nothing wrong with come of it. The electrical performance of the G1 is also nothing to brag about.
