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.
The PSU has a black casing, complimented by a square patterned grate at the rear, used as an exhaust to vent excess heat. The build quality of the Antec TruePower 550W is generally robust. It is of a standard design and has dimensions of 150 x 86 x 150mm and weighs in at an average 2.135kg.
The manufacturers' stated AC power input is 100-240V 8A -4A 50-60Hz. It comes with a total of 24 well selected output connectors; 1x ATX 24-pin connector, 1x CPU 8-pin connector, 1x ATX 4-pin connector, 1x PCI Express 6/8-pin connector, 1x PCI Express 6-pin connector, 9x SATA connectors, 9x 4-pin peripheral (MOLEX) connectors, and 1x floppy connectors.
A well-engineered PSU with very good overall performance; it leaves little in regards to improvements for its class and met the manufacturer's specifications for 100 per cent of its loads.
