Efficiency is Gold, but judging by the G2-1000's results, its efficiency is most likely closer to Platinum than Gold. Since it is based on a cutting-edge platform exploiting DC-DC converters, the unit is also fully modular and Haswell ready. It is equipped with all available protection features and the maximum operating temperature at which the unit can deliver its full power can reach 50°C, which is the temperature the ATX spec sets.

The 140 mm fan uses ball-bearings, which will have it last a long time. Contrary to the original Leadex platform, this one doesn't feature a semi-passive mode—the fan is constantly engaged.

With a length of 20 cm, the SuperNOVA G2-1300's dimensions are pretty large, but we do not expect a 1300 W monster to be housed inside a compact case. With ten years, the warranty is currently the longest among all competitors, and the price tag looks too good to be true! EVGA deserves praise for delivering such a richly featured product with a whopping ten year warranty at $200. Similar products by the competition come close to or exceed $300.

This unit's single +12V rail can easily start your truck if your battery dies. The lack of multiple +12V rails and the single rail's ability to deliver over 100 A max current will trouble some, but we prefer units with one +12V rail, even those with a monstrous capacity, though we should stress that PSUs with multiple rails are safer should something go really wrong.

The minor rails have enough capacity for a high-end system, and while 3 A will still suffice in most cases, a stronger 5VSB rail would be more appropriate for this unit.

Cables & Connectors, Power Distribution

6+2 pin PCIe (750mm) / 6 pin PCIe (+150mm) 2 / 2

4 pin Molex (550mm+100mm+100mm) 3
4 pin Molex (550mm+100mm) / FDD (+150mm)6 / 2

The unit comes with an ideal number of connectors for its capacity, although a few more PCIe connectors would provide an edge over the G2-1000. This PSU is for the extreme user and system after all. We would also like to see all PCIe connectors have 8 pins. All cables are very long, and the PCIe ones are even unnecessarily long, which may cause voltage drops at higher loads. 10 cm between each 4-pin Molex connector is too little, though 15 cm would be ideal. Most of the gauges on the 24-pin ATX cable are of 16AWG size, and all the other connectors utilize the standard 18AWG wires.

Since this PSU features a single +12V rail, we have nothing to comment on about its power distribution.
