Although it might be redundant at times, we tend to test multiple samples from the same OEM as time goes by. This can be a bit of a challenge from the reviewers stand point if the test units are as similar in results as they are in components. However, this is a good thing when it comes to seeing how consistent a company is at producing their products. Today's sample falls into that area. The only major difference between the SuperFlower Golden Green 800W unit, the Kingwin Laxer Gold 850W unit, and the NZXT Hale90 850W unit is the fact that SuperFlower decided to rate their own unit 50W less than the others. Is this due to internal changes? Will it perform as well as the other two? We will have to see.
