Product details
The RMx power supply series from Corsair is characterised by extremely precise voltage regulation, quiet operation, Gold-certified efficiency and a fully modular cable set. Thanks to the exclusive use of Japanese 105-degree capacitors, these power supplies are ideal for high-performance PCs where reliability is essential. The 80 PLUS Gold efficiency reduces operating costs and excessive heat. Zero RPM fan mode ensures virtually silent operation at low and medium loads. And the fully modular DC cables make system builds and upgrades a breeze, with impressive results.
