Corsair AX1200 for Quad SLI

post #1 of 12
Thread Starter 
I notice that Corsair AX1200 only supports 6 ports of 6+2 PCI-E power connector. Does that mean this power supply can only be used for tri-SLI max?

What if I want to install an additional card to make it quad-SLI? Can I borrow the "SATA / Peripheral" ports and convert them to 2 ports of 6+2 PCI-E? thinking.gif

I wouldn't try to "convert them" (Don't void your warranty by trying to make a pcie cable fit in those) I would use molex adapters, or if you want a better look do some tidy slicing on those wires.

Based on the overkill of the rest of your rig, what are you trying to quad sli? 580s? If you are just gaming you will be fine, but I PERSONALLY (OPINION) would be to not fold on a single psu.

Thanks Omega, yes a Molex adapter is what I am after here, not converter or any sort of weird modification. IIRC, the PSU comes with several bundles of extra cables, one of them is molex-to-pci converter.

Any reason why you would not fold 24/7 on a single PSU?

Just use a molex to 6 pin adapter. It's not as "safe" as the ntive 6 pin, but it works smile.gif.

These are 480s, and other guys at the evga forums said they were pulling around 1200ish watts from the wall with 580s.

The AX is a kick butt psu, trully one of the best, but I don't think anything can run at 100% load 24/7.

The problem is, anything higher than 1200 and you are going to be looking at special breakers and wiring for your house. Maybe just stick to tri sli for now? tongue.gif GL have fun with that beast of a rig though.

You need more than 1200W.

Silverstone Strider 1500W or two 700W+ PSUs on separate circuits. I recommend going as high efficiency as possible.

1200W from the wall is very different than what the PSU is actually outputting. Efficiency meeds to be factored in before you can say that its not enough power.

1200watts pulled from the wall is roughly around 960watts of load on the PSU with an 80% efficiency.

Factor in other components and heat buildup on the PSU, a lot would recommend you go with silverstone 1500 watts or just use dual PSU's like dual 850's

Another question: how would you rate Thermaltake Toughpower 1500W PSU? Is it any better than Silverstone Strider 1500W?
