Specifications

The EDG650 is Gold-certified, uses a fully modular design, can deliver its full power continuously at up to 50°C ambient, and is also backed by a full set of protections. The FDB fan ensures its reliability and there is no semi-passive mode, which is fine so long as the control circuit keeps fan speeds low at light loads. The dimensions of the unit are also a little larger than the norm, and the warranty period is long, though the unit is pretty expensive.

Antec is a firm believer in multi-rail PSUs, so this one features two +12V rails. Combined, they can deliver the unit's full power, which is the norm in modern PSUs. The minor rails can only deliver 100 W combined; however, almost no modern system will draw more from these rails, and the 5VSB rail has the minimum allowed amperage for a modern PSU.

Cables & Connectors, Power Distribution

There are many connectors; however, we would like to see an additional EPS connector, though most users with server mainboards in need of two will use a stronger PSU. Cable length is good overall, and our single complaint here is the small distance between peripheral connectors as there should at least be 15 cm in-between these. Nearly all connectors also utilize 18AWG gauges (only the sense wires are thinner).

As you can see, Antec tried to separate the PCIe connectors from the rest, and if you forgo connecting the EPS cable to the 16-pin socket, you won't be mixing EPS and PCIe connectors up, which is good as it could lead to OCP triggering and cause sudden PSU shut-downs, consequently affecting the system's proper operation.
