Efficiency is Gold since it is very difficult to meet all 80 Plus Platinum requirements with a high capacity unit, though we are pretty sure that the PSU's internal components are identical to those of the Leadex Platinum with 1200 W capacity. The features list includes, among others, the highly desired Haswell compatibility and a fully modular cabling design. SF also states that this unit is equipped with most protection features, including OCP (Over Current Protection), which is meaningless in this case. OTP is unfortunately missing; however, the unit can still deliver its full power continuously at a very high operating temperature of up to 50°C.

SF used a fluid dynamic bearing fan with this PSU. The best possible choice, this fan also costs more than a double ball-bearing one. The fan used is powerful and produces a significant amount of noise at high speeds, but its semi-passive operation, which can be disengaged if the user doesn't need it, will only engage the fan under tough conditions, making it inaudible at low and normal loads.

This PSU is 20 cm long, so make sure to check whether it can fit into your case before buying it (most modern ATX cases will support it without a hitch). The Leadex 1300W weighs as much as a PSU with such a monstrous capacity should weigh and is compatible with the ATX v2.2 spec, which is nearly identical to ATX v2.31, although this unit is only not compatible with the ATX v2.31 and v2.4 specs because both require at least two +12V rails and this unit only has one. The PSU comes with a five year warranty, and its price is highly competitive, especially for EU market standard, where hardware is generally more expensive than in the States.

The power of the +12V rail is intimidating since it can deliver more than 108 Amps! The maximum combined power of the minor rails is also enough for any modern system, even a very power-hungry one with lots of peripheral components/devices installed, but a stronger 5VSB rail with at least 4 A maximum current output would suit a 1.3 kW PSU more.

Like every 1300 W unit that respects itself, the Leadex features eight PCIe and two EPS connectors, and a great number of peripheral and SATA connectors. All cables are pretty long, and the distance among connectors is adequate. All of its gauges are 18AWG, which is the size the ATX spec recommends. High capacity units like this one usually use thicker 16AWG wires, but those make for very rigid cables that give users a hard time with cable management, though they provide lower voltage drops with high loads.

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