My PSU (800w) in my machine recently conked out on me and I had to replace it. So I bought a new 900w PSU (Rocketfish™ 900-Watt ATX CPU Power Supply : Rocketfish) to replace it. Setting it up and connecting all the cables was a breeze but when I got to connecting the GPU (Nvidia GeForce GTX 285) is when I completely blanked. The PSU has two 6-pin PCIe and two 8-pin PCIe connectors. The GPU has two 6-pin connectors on the back, too. So I initally connected the two 6-pins on the PSU to the two on the GPU. I thought I was good to go...but nooooooo. The card over heats like crazy (I'm talking about I almost burnt my finger just touching the top of the video card!) and then fails on me whenever I try to play any type of game/anything that is graphic intensive. Am I using a power supply that is too powerful? Or did I just connect it wrong? The reason why I think I connected it wrong is because I did some research and I heard all this talk about the different rails and amps on the PSU and how my GPU needs about 40ish amps on a 12v rail.....WHAT?!?! How do I know which rail I'm using? Any help would be appreciated!
