Would my power supply be enough and how much space do i need for sli

Hello

recently i built a computer but want to add another gtx 680 would my 750w psu be enough?

right now i have i7 3770k cpu overclocked to 4.5ghz, asus z77 maximus v formula motherboard, 2x8gb 1866 g.skill RAM, asus direct CU2 gtx 680 OC edition and a cosair h100. i also have 3x200mm and 4x120mm case fans.

would the power supply be enough? and would i need to consider liquid cooling? the dc2 gtx 680 are gonna be very close together on my maximus v formula

  1. We need to know what model 750W PSU you have in order to help you. A generic 750W, no way. A high-end 750W you bet. Middle of the road, maybe.
  2. ^ Agreed. GTX 680 Sli recommends an 800w power supply.

    So if you have a high quality 750w model you are likely fine. Seasonic, Corsair, XFX, PC Power and Cooling, Enermax, Silverstone ect.

    If you have some junk then no.
