    This power supply was a great replacement for my old supply that burnt out. Easy to install with modular cables for great management. Primary motherboard power supply is not modular, but all other cables are. Works flawlessly.

    This was purchased to replace my previous burned out power supply, also same brand. The other one have been running 24/7 for 3 years so not sure if it is typical but was reliable 24/7 for 3 years before it started creating a burned smell but still keep churning along.However, I replaced it anyway to be on the safer side.

    I replaced a failed power supply in a gaming computer. The specifications exceeded the specifications of the original supply in a number of areas and will support any expansion that I might want to do. The installation was simple and the supply has worked flawlessly since it has been installed.

    For a middle of the road modular power supply this does the job quite well. Very easy to install in my computer case and love the cleanliness of a modular system.

    My system requires a 650 watt unit so I installed this 850 watt because of the intensive rendering that I do in 3D Animation programs. I've had it for about a month and it works like a charm. Not once has it balked at the taxing work load I've subjected it to. Therefore, it gets a 5 star rating from me and yes, I would definitely recommend this to a friend!

    Not much to say on this one. I have an ASUS Z170 Deluxe motherboard along with an AMD Radeon Fury X graphics card along with 2 optical drive, several SSD drives and 1 traditional platter based hard drive all running off of this power supply. For those that are running one of Corsairs water cooling solutions that feature their Corsair Link software be aware that this PSU does not support the monitoring capability of that software. Otherwise it performs well in my system build.

    Installed this PSU in a mid level gaming rig with an ASUS Maximus VIII Hero board, Asus GTX 1060 GPU and 32Gb of RAM. Super quiet and Semi modular, so the CPU 8 pin connector and the Mobo 24 pin connector are hardwired to the PSU, other cables are modular which makes for a cleaner build.

    I replaced my old Corsair with this one, just because I had my old one for 2 years and it went out, I expect this one to almost do the same... but it worked good while it lasted.

    A Lot of Power at a Decent Price

    Considering this is a bronze series PSU, this is a good deal of power at a fair price. I need only half of the power for what I use the PSU for and it is good to have the extra room since I run it half load 24/7. If you want the best PSU from Corsair buy the AX and AXi Series. If you want a lot of power cheap from a reliable name, this is a good choice.
