Don't even ask about the PSU. The client wanted 1000W, so I put in 1000W lol. I recommended a 750W as well, but he wanted that 1KW. As for the RAM, the timings where just ridiculous at 2133MHz. I'm not an I.T professional by any means, but I know my way around Over Clocking, and the RAM just stuttered. They where at 7-7-10-28, or something like that. You cant tell me you are water-cooling all three GPU's and the CPU in a SINGLE loop are you? That would be ridiculous. You are going to want a double loop for that, and its not practical to run two loops in a 1200. Just my two-cents :thumbsup:
