I bought this to replace an existing 1000 watt PSU. I was hoping to just unplug the cables from the old PSU & plug them into the Corsair. No such luck as the connectors at the Corsair aren't standard. Not a problem, it just takes a little more time as you'll be replacing the cables.

Great power supply. Just upgraded from a corsair RM 750W. If you can pick this up on sale like I did, pull the trigger and buy this!

+1000W +Platinum Rated Efficiency +Super Quiet +Looks perfect aesthetically +Modular +Good layout for connections +Long life (Rated for 100,000 Hours

-Cables are moderately stiff; however, this doesn't bother me as I purchased aftermarket cables to match my blue build

Kitguru says: Another quality release from Corsair, and it is well priced considering the specifications.

competitively priced Platinum supply; well built; looks great; modular cables are first class; load regulation; very quiet; 7 year warranty

no shortage of competition in this sector

It goes without saying that Corsair has some of the best power supplies on the market. The AX1200i and AX1500i power supplies have redefined what it means to be the best of the best, and they have proven to be the closest we have ever seen to being a perfect power supply.

It a great 1 kilowatt power supply. It's an analog device, not a digital power supply but you save money with this unit. I bought a workstation motherboard on Ebay with two older generation Xeon processor and lots of ram and I didn't want to worry about power supply issues.

Rock solid performance; runs pretty cool and whisper quiet

A bit pricey but great return for the money

I am currently using this PSU for my 1st PC build. I have had zero issues with this unit in my Cooler Master Storm Trooper case. Everything runs perfectly, never had a random shut down, grounding issue or overheat.

An excellent power supply unit! I love the quet fan mode. Note: you must use 2 separate PCI-E power cables for AMD RX Vega 64 as this doesn't give enough power for a single cord/rail to support that card.

Overall I've been very satisfied with corsair's exceptional craftsmanship I absolutely love their H105 factory sealed liquid cooling and I'm just as happy with this power supply

Much quieter than my Thermaltake 500w psu; Nice easy to manage cables; Nice aesthetic, came well packaged with bags now used for spare component storage; Over all well built and a very easy installation and easy manage cables

None so far cables all fit snuggly into corresponding plug-ins unlike many have complained

The most surprising thing about this PSU for me was how quiet it is, most of the time the fan isn't operational. To get the thing under enough load for the temps to rise to the point where the fan actually starts is staggering and even then it's quiet.

Great PSU - easily takes care of a GTX 1080 SLI setup. Quiet (basically silent) operation. Stable and powerful. I found the Corsair software to be alright (hence the 4 star vs 5 star) and it clashed with some other config software on my computer. The other small letdown were the include cables.
