Corsair RM Series 850W Power Supply Review

The main subject of today’s review will be the RM850, which, as it model number implies, has a capacity of 850 W, making it the second-strongest RM unit. Corsair says to have equipped this and all other RM units with low-noise capacitors and transformers, and a semi-passive operation, a nowadays often sought-after feature to drastically reduce noise output. Its fan is also custom-designed to operate quietly—Corsair states it to be whisper quiet, even at high load. Our dB meter will clearly show whether this holds true.

Another interesting characteristic of all RM units is their compatibility with the Corsair Link system, though you have to buy it separately. Corsair Link, coupled with its appropriate software suite, allows you to monitor both fan speed and +12V current directly on your desktop. However, there is a catch: You can only monitor the fan speed and not control the fan’s operation, which would definitely be useful. But the need for special circuits would also increase production cost… at techPowerUp!
