Hey all, I want to replace the PSU in an old Aurora R2 ALX but I'm not too sure what I am doing! Or if it can be replaced. I have been looking at this one: CORSAIR TX850M Semi-Modular ATX PSU - 850 W It's in my price range and looks to be a good fit from what research I have done, but can anyone more experienced advise if they know this would work? Any advice, tips or suggestions for replacing the PSU would be ideal. Thanks all.
