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.

Fully modular cables; Incredible seven-year warranty; Exceptional ripple suppression; Semi-passive design; Fan-test button; Corsair Link; Great for overclocking; Ideal for multi GPU systems; Switchable single/multiple 12v rail; Sense wires + extra capacitors for voltage and ripple regulation

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.

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

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.

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.

The Corsair RM1000i PSU is excellent and almost silent as the fan only cuts in when required, it is fully modular with lots of available connections for most setups. I found the cables to be more than long enough for me, although the PSU is quite long it fitted in to my Antec P90 case no problem.

I am using this with my Sabertooth z87 mother board, with an i7-4770k @ 3.50 GHz, two samsung SSD 500gb, 2x 8gb memory sticks, my dvd-r and a big and beautiful memory card. The unit was easy to install. It's powerful, quiet and makes it easy to upgrade with multiple plugins for each cable.

The lowest-capacity unit Corsair's RMx line outputs up to 550W and is 80 PLUS Gold-certified. It features fully modular cabling, offers great performance and is nearly silent throughout its operating range, too.

Silent; full modular; usb monitoring; nice look

Cost

I personally went for it because of the 10-year warranty and the fully modular design. Very sleek and very quiet when the fan is in operation. Apart from the specifics, included is a handy bag to store the cables you are not using and a single USB motherboard header cable for the monitoring...
