Corsair RM850 PSU
Fully modular and optimized for silence and high efficiency.
It's built with low-noise capacitors and transformer.
Guaranteed to deliver clean, stable, continuous power!
The Corsair RM850 is fully modular and optimized for silence and high efficiency. It's built with low-noise capacitors and transformers, and Zero RPM Fan Mode ensures that the fan doesn't even spin until the power supply is under heavy load.
And with a fan that's custom-designed for low noise operation, it's whisper-quiet even when it's pushed hard.
80 PLUS Gold-certified efficiency
Highly efficient RM Series power supplies produce less heat and have lower operating costs. Designed with capacitors and transformers carefully selected to eliminate coil whine and other background noise that can be annoying in quiet environments!
Zero RPM Fan Mode
The efficient design of the RM850 means minimal excess heat generation, so the fan doesn't even need to spin under low to medium loads.
And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise
Flat black, low-profile modular cables
You can use only the cables you need, and leave the rest in the box for fast, easy, and great-looking builds.
