HX Series™ HX1200 — 1200 Watt 80 PLUS® Platinum Certified
Fully Modular PSU (UK)
Platinum efficiency, fully modular and virtually silent
CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential.
Quiet, efficient operation
80 PLUS Platinum efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads.
100% Japanese 105°C capacitors
Premium internal components ensure solid power delivery and long term reliability.
Zero RPM Fan Mode
Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads.
Ten year warranty
Your guarantee of reliable operation that will last across several system builds.
Power In Your Hands
Toggle single +12V rail or multi +12V rail mode. In the “SINGLE” position, the full output capability of the power supply’s +12V rail is available to any and all connectors, while in the “MULTIPLE” position, each individual connector has Over-Current Protection so no more than 40A of current can be delivered on any given cable.
The fully modular DC cables make builds and upgrades easy, with clean, great-looking results.
