Corsair CX850M

This power supply unit is an excellent choice for desktop systems, where high reliability, low noise levels, and flexible modular cabling are of the utmost importance. Designed for top-tier systems with multi-core processors, high-end graphics cards and multiple hard drives, its prestigious 80 PLUS Gold certification guarantees 85% efficiency, reducing excess heat and subsequent energy costs, even at high loads. Its stylish design with opaque finish transforms any system into a great-looking professional outfit.

The flat cables are modular, so you only use those you truly need. This reduces clutter while maximising airflow through the chassis. The thermally controlled 140mm cooling fan remains virtually silent during periods of standard workloads and ensures the effective and direct expulsion of warm air from the case when pushed hard.

Setting up a desktop system of practically any size is easy, thanks to the flat, sleeved cables. The CX850M's large voltage tolerance is handy during periods of power fluctuation. Active Power Factor Correction is of course included as well.
