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

Product Information

Five universal 8-pin connectors can be used with any 8-pin cable, satisfying all the power needs of modern motherboards and GPUs. The thermistor circuit that is used to measure the temperature for the fan controller and OTP has been changed in all RM750 and RM850 PSU’s moving forward.

Since the fan operates on both temperature and time delay, the temperatures raised too quickly for the fan controller to operate the fan. From individually sleeved cables in a variety of color combinations to 12-pin micro-fit GPU cables and 12VO motherboard cables, complete your build your way. Complement your system's look with CORSAIR Premium Individually Sleeved Type 4 Gen 4 PSU Cables (sold separately), available in seven different colors and patterns. Its fan is also custom-designed to operate quietly—Corsair states it to be whisper quiet, even at high load. 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).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. What are you powering with that PSU and how is the PSU oriented in the chassis (fan up or fan down)? While this is a design flaw that should have been avoided, I must say the way Corsair are handling this and your support is excellent.

In a sudden move a few days ago, they released the RM series sitting right between the HX and TX line. And, like all Corsair power supplies, the RM850 is built with high-quality components and is guaranteed to deliver clean, stable, continuous power. The ambient temperature of the room alone should be enough to maintain a lower operating temperature, so even prolonged operation at higher loads should give the fan controller adequate time to turn on the fan.All units of this series are, according to Corsair, optimized for silence, and their fully modular, low-profile, and all-black cabling solution also allows for fast and clean builds. CORSAIR provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds. So regardless of the fact the PSU can handle my system without problems now, i am thinking of the future.
