Pushing a PSU

[iamdarkyoshi]

So I kinda eventually maybe at some point sorta possibly in theory might buy a second r9 390x and watercool it with everything else.  I know it is not the most cost effective option. However, I want to know if an EVGA 750W Supernova G2 could do two 390x cards in crossfire and a power hungry 3930k. It seems to me like I would be pushing it pretty hard, but for these PSUs, 750W means 750w.

 

Thoughts? I always run the fan on it, never use fanless mode.

Just don't overclock lolol

 

The Supernova's are pretty good Power Supplies

What 750W? The Supernova NEX, G2,GS, B2, or GQ?

[boboman342]

Why not sell your one r9 390x and get a fury x or next gen amd gpu? An r9 390x isn't bad, especially for 1080p.

 

Like Jays2cents, you should buy the best components you can vs water cooling lower priced and lower performing components.

g2.

Do it, and if it blows then sue EVGA, you can probs even win it.
People won law cases on hot coffee.

Its very risky. You could power a 980ti and 4790k of a 350w but its not recommended.

Is it a GS or G2 unit? If it's one of those two, it can probably handle it. Would run it on a G1 series though.

Which would be better at driving triple 1080p 144hz? A fury x, or two 390x?

according to PCPP... no

PCPP is kinda silly sometimes

Neither haha

its barely enough

your PC will probably shut down due to power starvation

And then there is that friggin 6 core sandy bridge eating a fair amount of that, plus my pump and fans

two 980tis would work

[iamdarkyoshi]

two 980tis would work

They cost too much.

And with what CPU? PSUs can normally handle over their rated wattage by a small bit, a friend was running 1326W From the same PSU as me, a superflower leadex 1200W.

[iamdarkyoshi]

I think the best bet would be to liquid cool two nanos

for power consumption benchmarks sites usually use either a 4790k or 5930k or something in between

you can check it out on the tweaktown site

[The Official Czex]

I can pull 1050 on my 850W.

[AnonymousGuy]

You can usually overload a good PSU a bit.  Google reviews to see if any do overload testing.  Wouldn't susprise me if your 750 can work up to 850.

g2.

Go for it, the G2 series is great.

That would work.

I wouldn't overclocking too much but you should be fine.
