here is what i currently have.

CPU - i5-3570 @ 3.8Ghz
GPU - GTX 670 @ 1200Mhz
PSU - Corsair CX600

I am looking to add in another GTX 670 for SLI in the future, as well as buy an i7 Haswell cpu when they come out next year. I'm curious what size of a psu I will need to run two GTX 670 in SLI, as I assume a 600 Watt won't be enough.

calculators are good generic guessers. I would input your specs for the system your wanting-including the SLI setup-and then add 50-100 watts to that just to be safe, and go with a solid brand, the brands I prefer are Coolermaster and Antec, I have also had excellent experiences with OCZ and Corsair.

Alright, looks like I will get one with around 1000 Watts.

Also, I'm curious: Do all motherboards support sli? The one I have is the Gigabyte B75M-D3H, and I would like to know if I need to buy a new motherboard to run two graphics cards in SLI.

no, they dont all support them. Im going to say that motherboard should since it has 2 PCI express x16 slots and an intel chipset, that it should, however, keep in mind its only a micro-ATX motherboards, which tend to run hotter then full ATX to begin with, and it will shove the video cards closer together, and high end video cards take up two slots, cooling maybe an issue. If it were me, and I was planning on running an SLI setup with anything more then bottom line cards, I would use a full ATX motherboard such as this

Not all motherboards support SLI, your particular board does not supported.

Killer is correct, I take that back the board you linked only has support for crossfire, not SLI. you will only be able to run a single NVIDIA card on it, if you want to run multiple cards, you will need to run AMD video. The motherboard I have linked will support crossfire or SLI.


P.S. good catch killer, thankyou.
