Sure

As comparison on a GTX 580 Lightning 1.2 is the maximum voltage for the standard BIOS.
(Of course the real value differs marginally)

So if the TWFIII can handle it your heatkiller can too
But even though you are on water now and you can operate with higher voltages, still try to keep it as low as possible in correspondance to the stability of your clocks of course

Ok thanks KP. Thats good to know. Just remembered the max voltage is 1.15 on mine. Not really interested in flashing a different bios. This card was a pretty big purchase for me so I would be pretty bummed if I screwed it up somehow.

Hello,

I'm curious how big my PSU should be if I were to run GTX 580 in SLI? I currently have Seasonic X750, i7-2600k, 128gb SSD.

Do I have to go bigger? 850? 1000? or will my 750W be enough for the time being?

A 750W PSU would be enough to power it.
But literally only, enough.

If you take a healthy overclock of both the cards and other hardware into account a 1000W PSU would be optimal.
Also not stressing a PSU too much is benefitial to its life span

I recommend a 1000W for the optimal use and operation of a GTX 580 SLI setup and not having to be concerned about future expansions and overclocks

But it is always good to gather information from as many sources as possible

Tom's is NOT a reliable source when it comes to PSU's. 750W is enough to run 580 SLI heavy OC'd (<1200 core) in the long term. Of course a 850W would be more leeway but it isn't necessary.
G3D doesn't have a PSU testing set-up, TPU is fine but only the PSU reviews, not the forums.

They are only part of the biggest PC/Hardware/IT platforms and communities in the entire net, but yeah.

vcrazy, please do not listen to this, Tom´s Hardware is one of the most popular and known forums that exist.
Many highly knowledgeable and trained experts are part of it and share their wisdom, in all sections and areas considering Hardware & Co.

Although I have to admit G3D and TPU are not as sophisticated as Tom´s they still are to be considered professional.
You can without a doubt accept and follow the information offered in any of these forums considering your question

You can also use our club as guideline though.
Just check out the first page of the club ...the OC SLI Section features all of our members results with a link.
Click the link in order to see their sigs, ergo their PSU´s
