Specifications

Efficiency is Platinum, and the PSU can deliver its full power continuously at up to 50°C ambient, which is as the ATX spec recommends. In order to save money, all cables are affixed, which some users won't care about, although full or semi-modular PSUs are very popular nowadays since even a semi-modular PSU is often significantly easier to install, so most of us probably will fault this unit for its fully modular design. The Fortress-750 is Haswell ready because its VRMs (Voltage Regulation Modules) generate the minor rails, and OTP, although crucial, is, according the unit's official specifications, missing.

The cooling fan uses double ball-bearings, which will have it last longer than a plain sleeve-bearing fan. The unit is also pretty compact, and its price looks good if you take the hefty seven year warranty into account.

The single +12V rail can deliver the unit's full power alone, a typical situation in modern PSUs which utilize DC-DC converters to generate the minor rails. Speaking of the latter, their maximum combined power is low, although it will definitely suffice for your now-standard system. The 5VSB rail can delivers 2.5 A, which is considered the minimum for the rail.

Cables & Connectors, Power Distribution

The Fortress-750 comes with the for a unit of its category typical number of connectors. Some newer high-end PSUs feature six PCIe connectors, but we think that four are fine for 750 W unit. Regarding cable length, the main ATX connector should be closer to 60 cm long to avoid any problems with full-tower cases. All other cables are pretty long, and the distance among connectors is good, although some of you would probably prefer its SATA connectors to be closer to one another. The 24-pin ATX connector uses AWG16 and AWG18 wires, while the EPS and PCIe cables utilize AWG16 gauges up to their first connector and AWG18-sized connectors afterward. All other connectors use AWG18 gauges.

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