The PSU is 80 Plus Bronze certified and can deliver up to 550 W, so it falls into the mainstream category and mostly addresses small systems. It is fully modular and supports, according to OCZ, the newer Haswell CPUs, but our testing based on Intel's leaked guidelines shows that it doesn't. That said, you won't run into trouble if you opt to power a Haswell system with it, though this unit is not Haswell compatible according to Intel's unofficial testing procedure.

Its available protection features don't include OCP and OTP (Over Temperature Protection), and the 135 mm cooling fan is LED lit, uses a sleeve bearing. Like most Bronze units, this one doesn't feature a semi-passive operation, but has fairly large dimensions because it is 18 cm long. OCZ apparently didn't want to use another enclosure for the smaller Fatal1ty unit, so they used the same as that of the 750 W model. Finally, the warranty is set at three years, and the price looks good for its features.

Total Max. Power550W

The single +12V rail can almost deliver 500 W of power while the minor ones are quite strong for a unit of this capacity, or category. Finally, the 5VSB rail has the minimum allowed current output for a contemporary unit, which will suffice for a mainstream system.

Cables & Connectors, Power Distribution

Modular Cables
ATX connector (600mm)24 pin
4+4 pin EPS12V (650mm)1
6+2 pin PCIe (585mm) 2
SATA (400mm+150mm+150mm+150mm)8
4 pin Molex (400mm+150mm+150mm)8
FDD (+150mm)1

As expected, there are only two PCIe and a single EPS connector, and all are available at the same time. SATA and Peripheral connectors are surprisingly numerous for a 550 W unit, and we are obviously not going to complain about this, on the contrary. All cables are long enough while the distance between all connectors is adequate. Finally, all connectors use 18AGW wires, the recommended ATX standard.

Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution.
