Extremo Power ? I don't think so.
I installed an Extremo Power supply, 650 W Max, for a friend. He didn't have the money for a real power supply, so for 29 and change, he bought the Extremo. 2 weeks after it was installed he called me and asked me to take a look at his computer because it was making a clicking noise and freezing up when it did. Well I checked to see if any connections had come loose, nope. Then I thought, maybe the power supply is bad, it is new and I never heard of them before then. Well I did a couple of tests to see if it was. Much, not, to my surprise, it was not living up to the numbers on it. I tried to find out about the company and couldn't find anything on them. So I guess I could say that he bought the most expensive PS for his comp, without getting it as he did have to replace the one from Extremo. My thoughts, DON'T EVER BUY THE CEAPO EXTREMO, You WILL pay for it in the end.
