Corsair might have started off as a computer memory manufacturer, but today they sell a number of components for PCs. One of their most active product lineups is their computer power supply units (PSUs) business, with the company offering dozens of products through six different series.

The Corsair power supplies have been at the forefront of PSU design for many years now, being the first manufacturer to allow your system to monitor your PSU's power draw and other statistics using Corsair link is only just being emulated by other manufacturers.

Lots of connections for all those extras to connect power to. Plenty of wires included.

Great quality power supply. Provides stable power.

It has been ages since we have seen a power supply from Corsair that even hinted that it was anything less than of superior quality. Even then, it was a bare bones entry level unit that was simply designed to get you by and nothing more than that.

Good and fast service and can't go wrong with Corsair psu
