Specifications

The unit managed to meet 80 Plus Gold requirements despite its huge capacity, so it can deliver its 1.6 kW with 115 VAC very efficiently. Not many PSUs can do so with such low AC input, though it is no problem whatsoever with the 230 VAC in Europe. The G2-1600 also has a fully modular cabling design and is Haswell ready since it exploits a cutting-edge platform. Its protection features don't seem to include OTP (Over Temperature Protection), which is a big shame given it is a high-end PSU, while the unit's dimensions are huge, with its length reaching 22,5 cm. There is also EVGA's warranty of ten years—you can find EVGA's terms of warranty here—and the price is very high, especially compared to the G2-1300, but the platform this unit uses is completely different, which obviously increased production cost. We will be able to comment more precisely on whether its price is justified after having fully evaluated this unit's performance to calculate its incredibly important price/performance ratio.

For all you multi-rail lovers, this PSU is dedicated to you. It has a single +12V rail that can deliver more than 133 A, so it will easily feed anything you throw at it and have plenty of power left. Super Flower obviously sought to impress with the platform, and we are pretty sure they accomplished their goal to a tee. This is hands down one of the strongest PSUs available today, and its only real competitor is Corsair's AX1500i with, however, 100 W less capacity, although Titanium efficiency.

Compared to the +12V rail, the minor rails aren't that strong, but their 120 W combined maximum power output will always suffice. We would like to see a stronger 5VSB rail with at least 4-5 A in such a strong PSU. 3 A will get the job done in most cases, but there is no reason not to offer a stronger 5VSB rail that matches the unit's other capabilities.

Cables & Connectors, Power Distribution

The main ATX cable should be a little longer since this monster will probably go into a cave-sized full-tower case, so avoiding extension cables would be good. However, it is fully modular should you run into a compatibility problem, so buying another, longer ATX cable or, better yet, building one yourself if you have the right tools and the know-how is an option. The EPS and PCIe cables, on the other hand, are long enough. The distance between PCIe and SATA connectors is ideal, but we would like to see 13 cm, not 10 cm, between peripheral connectors. The main ATX, EPS, and PCIe cables use thicker 16AWG gauges for lower voltage drops, while all other connectors use standard 18AWG wires.

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.
