The Corsair PSU is aimed at enthusiasts purely. The power supply is a matte black and features red and black labels on the sides and back. Corsair is aiming this power supply at the high end enthusiast market and does not believe that incorporating LED lights and windows is where they should put their focus. Instead, they focus it on stability and raw power.

Opening the box up we found the power supply unit encased in a foam shipping housing and also inside was a modular cable bag, power cord, two plastic bags, and the owner’s manual. Opening up the cable bag we found 11 cables that can be used on the power supply.

The Cables:

  • 2 – 800mm 4 pin peripheral power connector cables (Molex) with 3 “quick release” style connectors
  • 2 – 450mm 4 pin peripheral power connector cables (Molex) with 2 “quick release” style connectors
  • 2 – 550mm PCI Express cables
  • 2 – 800mm SATA connector cables with 3 SATA connectors
  • 1 – 600mm SATA connector cables with 2 SATA connectors
  • 1 – Y-adapter cable with 2 floppy power connectors
  • 1 – Y-adapter cable with 2 4 pin female (Molex) “FAN ONLY” power connectors

Corsair has shipped eleven modular cables with their power supply, but the unit itself can only use up to seven of those cables at any given time. Corsair has actually given us a greater number of cables that what is required, so we can pick at choose what to run per our system requirements. During our use of the power supply we didn’t run into any cable length issues when we test fitted the power supply into some common cases when we checked cable lengths. One thing that I noticed is that the power supply comes with the 24-pin main power connector, 4-pin +12V connector and 8-pin EPS12V connector that cannot be removed. For all of the systems that we tested on the 4-pin +12V connector was not needed, so we had to hide the wire in our case.

Overall the PSU is one great piece of hardware, and shouldn’t be missed out by anyone.

I'm all about one thing: reviews that are easy to understand and make sense of.
