Corsair RM850, RM Series, 80 Plus Gold Certified, 850 W Fully Modular ATX Power Supply - Black

Product Information

A 135mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load. In a sudden move a few days ago, they released the RM series sitting right between the HX and TX line.

PLUS Gold rated efficiency saves you money on your power bill, and the low-profile black cables are fully modular, so you can enjoy fast, neat builds. This may (or may not) still provide sufficient aspiration (due to heat convection) where the PSU intake vent is on the top of the case, but would almost certainly provide insufficient aspiration where the intake vent is on the bottom.Not only can users choose to install only the cables they need, but they can add new cables with different connector configurations or customize the appearance of their PC with different color combinations.

For consistent, reliable power and superb electrical performance, each RM Series power supply features a robust resonant LLC topology with DC-DC conversion and 105°C rated industrial-grade capacitors.

The Corsair RM series power supplies are designed to run without active cooling for up to 40% load at typical room temperatures (25°C, or 77°F) and are capable of continuously outputting 100% of output capability at ambient temperatures of up to 40°C (104°F). RM Series power supplies are designed with capacitors and transformers carefully selected to eliminate coil whine and other background noise that can be annoying in quiet environments.

The fault was discovered when ambient temps were much higher (45°C) and without airflow, thus creating a smaller delta between ambient and operating temperature.This particular setup will probably cause some internal competition, but such competition always benefits the end consumer. Some fanless PSUs require a certain mounting orientation because they use the housing as a heatsink that needs to be exposed to the aspiration within the case or have vent holes that need to circulate air to/from the outside of the chassis. Modern Standby is a upcoming feature for Windows 10 that vastly improves your PC's sleep and wake functionality.
