Thermaltake Toughpower QFan 650W

Thermaltake promises robust power, hence the name “Toughpower.” We tested the 650 watt version of the QFan series.

The white fan keeping the power supply cool is fairly large at 140 mm, and it spins somewhat slowly due to its size. This is good news—lower RPMs translate to less noise output. The fan intake in the housing is designed to improve air supply even as acoustics remain manageable.

The power supply provides its own form of cable management. The SATA and 4-pin Molex connectors, as well as the PCIe cords, can be plugged into the power supply’s available 6-pin receptacles. They’re pinned differently, making it impossible to connect them incorrectly.
