Spire Blackmoon 650W review

The Spire Blackmoon 650W is a PSU that lends itself to systems for power-hungry desktop and mainstream gamers. It'll happily power a range of system components that include mid-range PCI-E graphics cards and SATA equipment and ships with two 12 volt rails as standard.During all of our testing the Spire Blackmoon 650W achieved 100 per cent of the manufacturer's performance claims, based on real-world scenarios. However the total efficiency for the Blackmoon lagged behind all the other low-end power supplies under test, including the Xigmatek NRP 600W and the Fractal Design Tesla 650W. It also failed to gain any ground in terms of standby efficiency, and was the lowest performer in its range. Compounding this poor power performance, the PSU was the loudest product under test in terms of decibel noise when compared to similar power supplies like the SilverStone Strider Plus and the Corsair HX 650W. The 120mm fan did do its job well, venting heat and keeping the computer cooler on the inside than the outside exhaust point, and the cables did not significantly heat up during the high load tests.
