The HX series power supplies from Corsair are characterized by extremely precise voltage regulation and virtually silent operation. Platinum-certified efficiency and a fully modular cable set are also included. Thanks to the exclusive use of Japanese 105-degree capacitors, these power supplies are excellent for high-performance PCs where reliability is essential. The 80 PLUS Platinum efficiency reduces operating costs and excessive heat. The Zero RPM fan mode ensures virtually silent operation under low and medium loads. Premium internal components provide solid power delivery and lasting reliability. Since the fan is activated only when needed, you can enjoy nearly silent operation at low and medium loads. You can switch between the +12V single rail mode or the 12V multi-rail mode. In the single position, the full power output capacity of the power supply's 12-volt rail is available for all connections, while in the "MULTIPLE" position, each individual connection has overcurrent protection, allowing no more than 40 A of current to be supplied from each rail. The fully modular DC cables make system builds and upgrades a breeze, and the results are impressive.
