Corsair PSU 1000W HX1000i, CP-9020074-EU

The HXi power supply series features extremely precise voltage regulation, virtually silent operation and a fully modular cable set. With 100% Japanese 105-degree capacitors, they are ideal for high-performance PCs where reliability is essential. The efficiency of 80 PLUS Platinum reduces operating costs and excess heat, and together with zero RPM fan mode technology, virtually noiseless operation is achieved. With Corsair Link Digital support, you can monitor power supply performance, switch between single and multi-rail modes, and control fan speed directly from your desktop. And the fully modular, flat cable harness makes builds and upgrades child's play, the results of which are impressive. The efficiency of 80 PLUS Platinum and zero RPM fan mode means the fans won't rotate at all at low to medium loads. And when you get the HXi up and running, the thermally controlled fans only turn as fast as they need to. But that's not all. It's quieter than most power supplies even when the fans aren't turning. The HXi is built with capacitors and other internal components specifically selected to reduce coil whistling and other electronic noise. Connect the supplied cable to the motherboard's USB header and download the free Corsair Link Dashboard application for Windows. Now you can monitor performance and efficiency, switch between single and multi-track modes, and control fan speed directly from your desktop. The fully modular flat cable set enables quick, easy installation and fantastic looking builds. The fan's self-test switch allows you to quickly check its operability before connecting the cables to the mainboard.
