Read the link...

OCZ are only bad when you have your system running close to the maximum rated power output of the PC a lot.

Only ability I have to read stuff on a computer is at work and they have that site blocked for some reason. Can I get a short breakdown of the article?

ATX specification has an "allowance" for 120mV. Mind you, test 6 was very stressful, pushing the power supply to it's limits, but it doesn't change the fact that the ripple exceeded spec and this is the first power supply to date I have had do this.

What's wrong with too much ripple? Well, if the voltage fluctuates too erratically, it can over work other regulators used to provide Vcore to the CPU, GPU, etc.

A representative of OCZ did find my findings concerning and asked that I return the unit for an exchange. I did so, and in the interim I obtained an FSP Epsilon 600W. The 600W version of the power supply the OCZ GameXstream is based on. In testing that unit, I found a good deal of ripple as well. When a brand new GameXstream was finally returned to me, I immediately plugged it in and found the same results as the first sample.

Fortunately, it is very unlikely any of us will have one of these power supplies at or above 400W, at least for any considerable period of time, but this high ripple measurement will be taken into consideration when calculating the performance score.

It's not a "bad" idea to get OCZ as they are very good power supplies aside from the ripple...
