SLI GTX 580s on TX750?

post #1 of 13
Thread Starter 
Hey everyone, I have a Corsair TX750. Within the next couple months, I will most likely be purchasing two reference GTX 580s. I was wondering if my PSU could handle it and if I wouldn't have to worry about anything. I don't have a CPU overclock and won't be overclocking the cards. Tell me what you think.

Thanks.

Probably too tight or won't work. I think the recommended is 850w from a goood PSU.

At stock speeds it will be more than enough.
See the power consumption numbers yourself at http://www.anandtech.com/show/4008/n...rce-gtx-580/17 -- note those figures at measured at the wall, so multiply by ~0.85 to get the DC watts.

A stock GTX580 uses ~ 230W Peak and 215W on Avg in games.. CLICK HERE..

So yes,a SLI GTX580 would run just fine on that PSU if the cards were left on stock clocks..

CPU can be OC'd without any issues..


CHEERS..

Yeah it will be a bit tight, but should be able to run them fine. However, depending on how old your TX is, it may have some issues down the line. PSU's degrade over time and the amount of power they can supply is reduced. I'd prefer to have more overhead for efficiency and longevity reasons.

Yes TX750 is fine... just don't OC them... plus I don't see why you would need to OC them anyways.

I would say yes, and you could probably do some light OC'ing if you wanted to. I'd OC the CPU over the GPU's though.

Yes, I will OC the CPU one of these days

You'll be fine at stock but don't be running furmark or anything, you might be able to get away with a 'minor' overclock but I would recommend purchasing a 850w PSU and overclocking them badboys to unleash the full power!!.
