Antec TruePower 550W

Antec TruePower 550W review

Aimed at power-hungry desktop users and the more ambitious gamer the Antec TruePower 550W can deliver power to a range of system components that include dual GPUs and dual/quad-core CPUs from its four 12 volt rails.Rather impressively in regards to total efficiency, the Antec TruePower 550W led the field, beating out other lower-range power supplies in its class, including the Xigmatek NRP 600W and the OCZ StealthXStream 2 600W. It also achieved a very respectable third place out of seven contenders in terms of standby efficiency, narrowly losing out to the OCZ StealthXStream 2 600W and the Corsair HX 650W. This PSU produced slightly more decibel noise compared to similar power supplies in its class like that Xigmatek PSU and the Fractal Design Tesla 650W, although it was still among the quietest under test. The 120mm fan performed well to vent heat and the cables remained fairly cold during high load testing. Throughout all the testing the Antec TruePower 550W achieved 100 per cent of the manufacturer's claimed performance over its 12 volt rails.
