1000W Corsair RM1000i, Full Modular, 80PLUS Gold, SLI/CrossFire, Single Rail, 83.3A, 135mm Fan, ATX PSU is rated 4.1 out of 5 by 8.
Rated 5 out of 5 by from Very good power supply This is a very good power supply. I've been using it for while now and it's been great so far. I do like the Corsair link software where you can see the power usage etc.

Rated 5 out of 5 by from Very quiet with an exceptionally long warranty for a pice 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 functionality. The monitoring functionality via a USB header is a nice tool but I rarely use it but for those who do like to tweak and keep an eye on any aspect of their PSU operation it is an excellent feature. It comes with a handy feature that stops the fan when the load is low. So unless you are going to power a few GPUs it will probably stay off. It would be nice if the limit could be adjusted and considering the price I would have expected it. For the price, I am disappointed Corsair did not include cable clips for cable management, such as an ATX set of clips and some PCIe power cable clips as well as some SATA power ones. A disappointment but not a deal breaker. Its overkill for my setup as I only have a Gigabyte 1080 G1 and an i7 6700k. Overall I would definitely recommend it, the warranty alone makes this a perfect buy even when considering the price.

Rated 1 out of 5 by from Poor QA Bought this product, was broken so exchanged on warranty, second one also broken, got a refund and bought EVGA g2 instead

Rated 5 out of 5 by from Power to the PC. I needed a psu that had 1000 watts and this does not disappoint. It is fully modular and comes with a large selection of leads. You can connect it to the motherboard via an usb cable, to see and regulate all the voltages. The first one I had was faulty, but Scan came to the rescue and I soon had a new working one. It is quiet and the fan stops turning at low loads. All in all a great psu.

Rated 5 out of 5 by from Powerful skylake build with i7 6700, 980ti classified and watercooling and the fan still doesn't turn and it's Def not broken, this thing is a powerhouse. and the monitoring software is pretty good too.

Rated 5 out of 5 by from 1000W Corsair RM1000i Very nicely built unit. Operates around 26C and pulls 112 watts in for 98 watts out when idle. System comprises of an Intel Core i7-4930K Ivy Bridge, five hard disks (SSD & HDD) with two GTX 970s. Very happy I could face the unit fan down to pull air from outside the case through a dust filter. Makes the system noticeably quieter as the fan is not operating below 40C. A little on the pricey side but I believe I will get many years trouble free use from it. And of course you should never cheap out on a PSU.

Rated 2 out of 5 by from Cant power 12 HDD's Pros: Looks Good Fan is quiet Cables are decent Cons: Cant power 12 HDD's - it will, but only on staggered boot which is pretty useless
Date published: 2016-03-21
Rated 5 out of 5 by from Great PSU!! As far as power supplies go this one is brilliant. No problems with installing it. It stays cool and the Corsair Link software is very useful for monitoring. More than enough cables (Came in their own bag!) for any use and very quiet.
