Good solid performance; obviously I cannot comment on long term usage.

Corsair's been in the power supply business for quite a few years now. Lately, some have charged that they have lost their way in the marketplace, offering units that cost more than the competition and offer less performance.

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.

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.

Kitguru says: The high power RM1000x delivers great load regulation, ripple suppression and achieves 80 Plus Gold Certification. The low noise NR135L fan only switches on when the load reaches 400watts, or higher. At £130 it is very competitively priced.

great build quality; all 105c Japanese grade capacitors; ripple suppression; type 4 cables; low noise

Corsair have so many supplies available right now; we think some people will be confused on which they need

The RM1000i isn't cheap, clocking in at £144.95 from Overclockers UK . Of course, the old saying that you get what you pay for rings true and there's no doubt that this is a premium quality product. I'm very impressed by the latest Corsair power supply.

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.
