Corsair HX1000W Modular Power Supply Review

Author: Lee Garbutt
Manufacturer: Corsair Components

Specifications and Packaging

The Corsair HX1000W power supply is rated for a combined, continuous output power of up to 1,000 watts at 50°C operating temperature (internal case air temperature).  That’s important, as some less reputable manufactures limit their power supply’s advertised capacity by specifying a lower operating temperature (25°C) in the fine print.  The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid. 

The Corsair HX1000W PSU incorporates two independent secondary sections, which appear almost identical from the outside.  One secondary produces the +12V1 and +5V outputs while the other one produces the +12V2 and +3.3V outputs.  Each secondary is rated for up to 500W and is capable of delivering 40A (480W) of +12V power with a combined total +12V output of up to 80A (960W).  And as we will see later, the secondary sections are populated almost exclusively with solid polymer capacitors for extended performance and reliability.

The following table list the HX1000W PSU specs from Corsair’s website.

Packaging and Parts

The Corsair HX1000W power supply arrived securely packed inside a large retail box that highlights the power supplies features and specifications along with the new blue theme color.  In addition to the power supply the package includes a power cord, 13 modular cables in a Nylon storage bag, mounting screws, Corsair case badge, package of cable ties, and a printed User’s Manual.
