HXi Series HX850i 850W '80 Plus Platinum Digital Modular Power Supply (CP-9020073-UK)

HXi Series power supplies give you extremely tight voltage control, virtually silent operation, and a fully modular cable set. With all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Platinum efficiency reduces operating cost and 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 single rail or multi rail mode, and control fan speed directly from your desktop. And, the fully modular, low profile cable set makes builds and upgrades easy, with clean, great-looking results.

80 PLUS Platinum efficiency and Zero RPM Fan Mode mean that at low to medium loads, the fan doesn’t spin at all. And when you do push the HXi hard, the thermally controlled fan spins only as fast as it needs to.

But that’s not all. It’s quieter than most PSUs when the fan’s not spinning, too. The HXi is built with capacitors and other internal components specially selected to reduce coil whine and other electronic noise.

Connect the included cable to a motherboard USB header and download the free Corsair Link Dashboard application for Windows and you can monitor performance and efficiency, toggle single rail or multi rail mode, and control fan speed directly from your desktop.

The fully modular, low-profile cable set allows for quick and easy installation and great-looking builds. The fan self-test switch lets you quickly confirm operation before you even attach cables to your motherboard.

- Corsair Link™ Integration for monitoring performance and adjustment of fan speed and multi-rail/single rail mode.
- 80 PLUS® Platinum efficiency, delivering 92% energy efficiency at real world load conditions.
- ZeroRPM mode for fanless operation at low loads and outstanding noise reduction.
- 140mm thermally controlled fluid dynamic bearing fan spins up as needed.
- Fully Modular low profile cables for easy installation, less clutter, and helps maximize airflow through your computer’s chassis.
- Engineered to meet maximum power output at a server-grade 50C temperature rating.
- Fan self-test switch to determine fan functionality even before installation.
- Over-voltage protection, under-voltage protection, and short circuit protection, over power protection, over temperature protection provide maximum safety to your critical system components.

Great PSU from Corsair

Have been using this for a few years now with no problems at all. There is no coil whine, the fan never spins up and as a result it is silent. Handy linked to iCue to monitor input and output wattage. Cant go wrong with this PSU.

I’ve had this PSU for years no, still going strong. No coil while, although it does seem to illicit a lot of whine from my GOUs.

It works seamlessly with my Corsair Link kit, looks great and is super silent.

Got a beautiful Cablemods kit to go with it, couldn’t be happier.

WantoN 2018-11-18


To put simply, its not worth the time. I thought what were the chances that mine would have coil whine and guess what it did. Its a nice PSU but the fact that so many reports have put that they've awful coil whine I wouldn't say risk it.


Good psu

Had to RMA my first one as it had coil whine but the process was fast and easy... My first RMA! The second one works like a dream no problems at all! Works great With corsair link makes everything easy to monitor!
