The black HXi Series HX850i 850W 80 Plus Platinum Certified PSU ATX Power Supply Unit from Corsair offers tight voltage control, virtually silent operation, and a fully-modular cable set. Equipped with a 105°C capacitor, it is designed for high-performance PCs where reliability is essential. The 80 PLUS Platinum efficiency reduces excess heat, and together with Zero RPM Fan Mode technology, gives you virtually silent operation.

With Corsair Link Digital support, you can monitor power supply performance, toggle between single-rail and multi-rail mode, and control fan speed directly from your desktop. The fully-modular low-profile cable set makes builds and upgrades easy with clean results.

Quiet, Efficient Operation
The 80 PLUS Platinum efficiency and Zero RPM Fan Mode mean that at low-to-medium loads the fan doesn't spin at all. When it is pushed hard, the 140mm thermally-controlled fan spins only as fast as it needs to. The HX850i is built with a capacitor and other internal components specially selected to reduce coil whine and other electronic noise.
Corsair Link Digital for Advanced Monitoring & Control
The HX850i connects the included cable to a motherboard USB header and downloads the free Corsair Link Dashboard application for Windows, following which you can monitor performance and efficiency, toggle between single-rail and multi-rail mode, and control fan speed directly from your desktop.
Easy Installation
The fully-modular low-profile cable set allows for quick and easy installation and pleasant-looking builds.
Temperature Rating
The HX850i is engineered to meet maximum power output at a server-grade 50°C temperature rating.
Fan Self-Switch Function
The HX850i features a fan self-test switch to determine fan functionality even before installation.
Voltage Protection
Over-voltage protection, under-voltage protection, short-circuit protection, over-power protection, and over-temperature protection provide maximum safety to your critical system components.
Safety and Agency Approvals
The HX850i is compliant with FCC, ICES, CE, UL / CUL, CSA, C-Tick/RCM, TUV, CB, CU, KC Mark, RoHS, WEEE, RoHS (China), and REACH.

    HXi Series HX850i 850W 80 Plus Platinum Certified PSU ATX Power Supply Unit (Black) is rated 5.0 out of 5 by 7.
    Rated 5 out of 5 by from Great PS I love the modular design of the power leads. It is sometimes confusing when swapping out the supply. Having to disconnect everything, removing the old supply and installing the new one while hopefully get everything right. With the Corsair modular design, I just pulled the plug off the board or card and inserted the modular Corsair plug in its place. Once the board, fans and peripherals are connected it is a simple matter to then plug into the power supply and mount it to the case!

    Rated 5 out of 5 by from Excellent PSU, No Complaints The HX850i has a tad bit more power than my system needs, but provides room for expansion if needed. No complaints and works like a charm. I also love the LINK software which provides me information about temps, voltage of not only the PSU, but my entire system. Definitely recommend if creating a higher end gaming or editing/graphics system.

    Rated 5 out of 5 by from hx850i runs without a hitch. other reviewers might have complained about the snugness of the 24 pin power connector but i simply plugged it in before putting my mobo in the case. took 10 min but being careful and moving it down one side then the other and not ogre handling it, it went in fine.

    Rated 5 out of 5 by from Simply worth the money in my mind I love the USB link to the power supply and the monitoring and usage feed back. One of the most advanced PS I've owned and I love it! Powering my new Threadripper build like a champ
