80+ Gold rated PSU with full jap capacitors, can't go wrong with this.

Nothing to complain about.

Took a star off because it's hard to find braided cables that are compatible with this PSU. That being said it runs fanless when not under load which is very nice. Included cables are a little stiff.

Tier 1 or 2 unit. 80 Plus Gold certified, fully modular, stiff cables that stay where you put them, nice and quiet, sturdy look and feel, all Japanese capacitors. Hasn't given me a moment's trouble yet.

Everything turns on and I don't have random restarts like I did on my old system! Used to have a lower model Corsair 450w which would cut out during intensive GPU load.

Great PSU, fully modular, loads of cables.

The silent running is a god send! The fan doesn't spin up when under low/medium power consumption, only when it hits high will the fan turn on, even then is hardly noticeable.

A fully modular unit for cable management, a larger capacity to ensure consistent power and upgrade ability for other components, and a Gold Plus rating was key.

Great power supply! I need a bigger one though, my GPU is right at the brink.

A great gold-rated PSU. One of the better PSUs out there, for a good price. Nearly zero ripple according to tests. Efficient.

My personal favorite feature: the fan stays completely off under light to medium loads, so it's dead silent with normal use.

Nice power supply. It came with all the cables I needed (and then some), along with a nice bag to keep them in so they're organized and not just scattered loose in a desk drawer. The jacks are all labeled well, and most of the cables are labeled for where they go. It was straightforward to wire, and like other modular supplies it keeps the cable clutter down. The cables are all wrapped in a mesh sleeve, so they're reasonably attractive when viewed through the case window.
