Asus gtx 780ti direct CU II SLI

[Ashley Walker]

Will a corsair 860 PSU be enough to handle 2 of the above GPUs?

I already have one 780ti, I was just looking to slowly make an overkill rig. I am aware I will be needing to overclock my i7 3770k to enable full bandwith usage.

Any help will be greatly appreciated

I'd say that was cutting it VERY close...

RealHard Tech say 950W. They allow some overhead and allow a bit more for crappy power supplies.

If you don't want to overclock then I'd say you'd easily be OK.

No problem.

Here is Guru3D's power supply recommendation:
•GeForce GTX 780 Ti - On your average system the card requires you to have a 550 Watt power supply unit.
•GeForce GTX 780 Ti 2-way SLI - On your average system the cards require you to have a 800 Watt power supply unit as minimum.
•GeForce GTX 780 Ti 3-way SLI - On your average system the cards require you to have a 1200 Watt power supply unit as minimum.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.

I looked at that a thought it was for the reference cards. With the ASUS version being factory overclocked I thought it might be cutting it a little close with only 60W headroom.

Sorry, I should have linked the Asus DirectCU review. Only 1 watt more than the reference!

And same for the high-end Asus Matrix card.

also in another note. the gtx 780 ti requires 2x 4 pins connections for each GPU. at least it does on my asus gtx 780 ti CUII

2 x 8

Absolutely! The Corsair 860 is a high end power supply...
