Silent Pro M is the latest power supply series from Cooler Master, featuring modular cabling system and single-rail design, with 500 W, 600 W, 700 W, 850 W and 1000 W models available. Today we are going to test the 850 W version from this series (RS-850-AMBA-J3), which is scheduled to reach the market by the end of this month, and see if it will survive our tests.
