Efficiency is Gold, and the PSU features a semi-modular cabling design and a semi-passive operation, which will keep the fan from spinning up at lower loads. It is also Haswell ready since it features DC-DC converters. The maximum operating temperature at which it is able to deliver its full power continuously can reach up to 45°C, and it is equipped with all the protection features, including OTP (Over Temperature Protection), which is always nice to see. The 135 mm fan uses double ball-bearings for more longevity and the warranty is long enough at five years, but its price is rather high.

The single +12V rail can output the full unit's power by itself, which is the norm for today's PSUs. The minor rails are also pretty strong at 130 W combined output, and the 5VSB rail is sufficiently powerful.

A large number of connectors equip the PSU, including eleven SATA connectors! There are also two EPS cables with an equal number of connectors and three PCIe cables. Two of these are modular. There are a total of four PCIe connectors.

All cables are long enough for even large cases, and the distance amongst connectors is adequate. The modular cables are flat and stealth, making cable management tasks much easier. All native cables are, on the other hand, pretty stiff, which will make cable routing difficult. The reason behind their stiffness is their use of thicker 16AWG gauges for lower voltage drops at higher loads, while the modular cables use the standard 18AWG wires.

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