Specifications

This unit is capable of delivering its full power at 50°C continuously and is Gold certified. It is Haswell ready since it uses a modern platform with DC-DC converters for the generation of the minor rails. All cables are modular, which, combined with its compact dimensions, will make its installation a breeze.

The unit doesn't feature Over Temperature Protection (OTP), which is unusual for a Leadex platform. OTP is crucial, especially if the PSU features a semi-passive operation, which can dramatically increase internal temperatures in cases were the PSU has, for example, been installed with its top exhaust grill facing downward. Absolutely make sure to avoid installing semi-passive and passive PSUs in such a way. Should a PSU's fan fail, only OTP can save the day. In short, every PSU platform should include OTP.

A low-speed, double ball-bearing fan that will last for quite a long time, especially if you activate semi-passive mode where the fan will rarely engage under normal operating conditions, keeps the 650 G2 cool. At seven years, the warranty is quite long, and while the price might seem high, it is fine considering this product's features.

The single +12V rail can deliver up to 54 A, and the minor rails have a combined capacity of 110 W, which is enough for today's standards. With 3 A maximum current output, the 5VSB rail is also stronger than most.

Cables & Connectors, Power Distribution

EVGA equipped this PSU with two EPS and four PCIe connectors, and all are available at the same time. Make sure not to overestimate the capabilities of a 650 W PSU. There is enough capacity here for two GPUs with 200 W maximum power consumption each; however things will go south with more power hungry GPUs and a highly clocked CPU.

The are a lot of SATA and peripheral connectors, enough to cover the needs of a system that doesn't need a stronger PSU. The peripheral connectors are spaced 10 cm apart, which is very little. There should at least be 13-15 cm between these since most components fed by peripheral connectors are pretty far apart from one another. The 24-pin ATX, EPS and PCIe connectors use thicker 16AWG gauges while all other connectors use 18AWG wires. Only higher capacity PSUs tend to use 16AWG wires; however, EVGA either meant to provide the best-possible load regulation or Super Flower didn't want to manufacture a different set of cables for their lower-capacity G2 units, which had them use the same cables as for the stronger members of the line instead.

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