I plan on buying another 660 ti to run it in SLI with my other 660 ti, but I just want to make sure that my PSU is good enough. I currently have a 750w Antec psu that came with the Antec 1200 case I bought a while ago. Will this be enough to run the cards? Thanks in advance.
The card can even run on a 500watts PSU without any power bottlenecks. Your PSU is just too good for the card. Also assuming the PSU is atleast 80 plus certified since it is from antec.
The Antec 750W will be more than enough for 2 660ti. Your system probably won't draw more than 600W under load. You have nothing to worry about.
