Getting on towards Platinum quality. One key challenge facing power-supply unit (PSU) manufacturers is how to differentiate between a number of supplies that all vastly exceed the lax minimum standards laid down by the ATX specification.

It is difficult to find a PSU that doesn't score well when pushed and probed by specialist equipment, so manufacturers tend to decide between the competing factors of quality, connectors, modular cabling, semi-passive running and take account of all these with due reference to price. It also helps that the 80 PLUS organisation provides an at-a-peek reference to a supply's internal quality.

With all this in mind, Corsair has consolidated its PSU offerings into seven model ranges. Slap bang in the middle is the ATX-sized TX-M-series, and 2017 sees serious revamp of its performance credentials.
