Power supplies of course are one of the most important pieces of a computer and one component where quality is extremely important, at least if you are a serious user with some high-end components in the computer. We have unfortunately seen too many computers get unstable or even worse, go up in smoke, when a no-name PSU has buckled under the load.Enermax is a company that is known for their high quality PSU’s and today we are looking at a new product from them: the PRO87+ 600W CrossFireX™. As the name suggests this is a 600W PSU with a high efficiency rate (87% and better) which also happens to be certified for CrossfireX.
