Hi folks im looking to upgrade from asus dcu2 gtx680 in sli to ASUS GTX780TI-DC2OC-3GD5 in sli and im on a corsair hx750 , will this psu be adequate. My cpu is an i7-3700k oced to 4.6 on an asus p8z77v-pro with 8 gig of ram . thanks
you can get nice 1000w psu for good prices btw, i feel your x2 780ti and 750w doesn't cut it, not with your overclocked cpu.
I wouldn't chance running two 780ti's on a 750w tbh, I'd say that 850 is the bare minimum and even that might be pushing it. Why not wait until we hear more about the 800/900 series? From what we understand so far they'll use less power and have more memory, could end up saving you a PSU swap if you can wait. http://www.anandtech.com/bench/product/1073?vs=1064
i'd take x2 780 6gb, nice msi ones over x2 780ti. just the ram speed that's nerfed somewhat, unfortunately. evga titanB sc can be had for £600, which i'd take over x2 780ti also. though Hilbert's vrams got real hot in the review.
If you can afford 2 780ti, get a more powerful psu with some headroom like a quality 1000w, I would not chance 2 780ti on a dinky 750 watt tbh.
