2 GPU's Gigabyte 660oc Tags: Graphics Cards GPUs Gigabyte Graphics Last response: December 4, 2012 4:59 PM in Graphics & Displays Share Nyck001 December 4, 2012 4:38:02 PM Evening All, Hope you are well, recently i have taken much interest in running 2 GPU's and want some help with this, im a bit of a nub when trying to explain this, but hopefully it will make sense. I have recently purchased a new mobo, for SLI and its compatable. It has 2 PCI-E slots. I then purchased a Gigabyte 660OC. And now i want to buy another, run SLI. My PSU is the damn problem, the gpu's state a min of 450w. My question to you is, should i then be looking to get a 900w PSU or could i save a little money and go for a 700? 800W? Thanks in advance!

The 450w number is for 1 card and everything else. When adding a second card you don't have to factor in the CPU and the rest of the components in twice. A handy reference list. http://www.realhardtechx.com/index_archivos/Page362.htm Make sure to get a quality unit. Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, Antec and the higher rated Rosewill units would all be brands I trust. Can't find your answer ? Ask !
