Specifications

The PSU is 80 Plus Platinum certified and its maximum operating temperature reaches, as ATX specifications recommend, 50°C. Its protection features even include OTP (Over Temperature Protection) which is, in our opinion, crucial in a PSU.

A 120 mm fan, equipped with double ball-bearings for increased longevity, handles cooling the unit. The PSU's dimensions are pretty compact, which ensures that it is compatible with most cases. Finally, the warranty is, like with all high-end Corsair PSUs, extra-long at seven years; a future buyer won't have to worry about another PSU for a very long time.


This is, normally, a single rail PSU, but its provided software allows you to set an OCP for each PCIe socket of the modular PCB. The +12V rail can deliver the full unit's power, something that is usually seen in PSUs utilizing DC-DC converters for the generation of the minor rails. Speaking of the minor rails: their maximum combined power is enough for a modern system's needs, and the same holds true for the 5VSB rail.

Cables & Connectors, Power Distribution

Two EPS and six PCIe connectors are available at the same time. Corsair made the right choice by equipping this unit with six PCIe connectors since they make supporting up to three high-end VGAs possible. The PSU also has plenty of SATA and peripheral connectors. We normally only find as many available connectors on PSUs with more than 1000 W capacity.

The length of all cables is sufficient and won't cause any problems, even in a full tower chassis; however, the distance amongst peripheral connectors is small, and should, ideally, be 150 mm. The relativly short distance amongst SATA connectors may , on the other hand, come in handy since HDDs/SDDs are usually installed a short distances apart from each other.

The 24 pin ATX connector uses thicker 16AWG gauges for lower voltage drops, especially at high loads, while all other connectors, except for the FDD ones, use the standard 18AWG wires.

Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution, except that you can set OCP at each modular 8 pin socket through the provided software.
