Will this be able to handle two 670's in SLI?

[Justhavocman]

Hey there , im upgrading my psu to http://www.visionstudio.gr/prodinfo....step=undefined , i know it can handle a single 670 with easy but will it be able to handle two in SLI?

[Pill Monster]

Yeah.

[PhazeDelta1]

No. That PSU only has 2 x 6+2 pin pci-e cables.

[Pill Monster]

I guess not.

Seems like we've got two opinions here :p Could you recommend a PSU that is SLI capable for under 100 euros?

Ill second that recommendation.

Always best to get a quality psu, at least it's guaranteed to give out the power it says.

I just happen to know for a fact that as it's got a single 12v rail, it's more than likely that it can run 2x GTX 670.

Example: my i7 920 is a C0, and breaking the 3.8GHz barrier takes quite the voltage increase, just to reach 4.0. That's a C0 for you. So that's some extra power consumption there. Back on topic:

Now, I also just got an eVGA GTX 670 FTW. And it just so happens my brother, whom I'm building a rig for once the last few parts arrive, has gotten the exact same card. Now as they've both arrived before the other parts, we decided to test them in SLI in my rig for a day - just for kicks.

Turns out my 650 watts Corsair TX650 is more than capable of handling them both at once. Tried it in Battlefield 3 maxed for hours, tried it in Hitman: Absolution, and Far Cry 3 - even Heaven benchmark 3.0. All maxed of course. It's also got a single 12v rail, with 56 amps on it (something like that, can't remember exactly) - which in this case is plenty to run two 670 FTW Editions at once, along with an overclocked i7-920 C0.

So judging from my own experience, the PSU that you linked should be able to handle it just fine, as it's also only got a single 12v rail (can't find out how many amps it's on, but I'd imagine 60-62ish?), is the same brand (Corsair), and is in theory capable of handling 50 watts more than mine. I obviously can't take any responsibility if your results vary, but I highly doubt it.

People overrate wattage big-time, and most often underrate the significance of amps on the 12v rail(s).

Hope I could be of any help; it took a while to type this wall-of-text

I admit that I may be slightly high, but even my GTX 670 FTW came with two molex-to-6-pin converter cables. Works for me like that in SLI. And my Corsair TX650W also has only 2x 6+2 pin connectors.

I'm still pretty damn sure that 700W Corsair, with a single 12v rail, should be enough. Assuming he has 4 molex cables free.

So yeah the PSU can handle the load, it just doesn't have the proper connectors. You can use adapters although this is normally frowned upon as seen by some responses.

That may be a last resort if you already own the PSU and are looking to add an extra GPU.

However, the OP is buying new PSU so has absolutely no reason to shortchange himself by purchasing a model with only half the required PCI-E connectors.

I agree it's serious but I still lol'd when reading your comment.
Sorry.

HAUI... < that is funny


Recommending spending money (and time) on a part that doesn’t cut it, isn’t funny.
