Hello, I've made myself a pc build for gaming, budget is maximum $900, would be ideal arround 800-850$ I'll be mostly using it for games and some video recording and editing and surfing the net. I plan to get SLI working in the future and I'm not sure what psu I need to get. I want to buy one that will work in the future with SLI so I won't need to buy a new one. Basically, here's the build, tell me what you think about it. Also, I don't need a optical drive or windows.
