Quiet, efficient operation 80 PLUS Platinum efficiency & Zero RPM Fan Mode mean that at low to medium loads, the fan doesn’t spin at all. & 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 & other internal components specially selected to reduce coil whine & other electronic noise. Corsair Link Digital for advanced monitoring & control Connect the included cable to a motherboard USB (Universal Serial Bus) header & download the free Corsair Link Dashboard application for Windows & you can monitor performance & efficiency, toggle single rail or multi rail mode, & control fan speed directly from your desktop. Easy Installation The fully modular, low-profile cable set allows for quick & easy installation & great-looking builds.
