PSU Roundup: Performance, Price, Efficiency


Efficiency-wise, Thermaltakes’ power supply falls into the middle of the pack. Its most promising value is at medium load—a respectable 86 percent. At full and low loads, it’s about 84 percent.

In standby mode the device consumes 1.4 watts. At a load of 2.5 watts it uses 4.90 watts. We think that these results could be better.
