Going for mainstream excellence. Corsair has revamped its popular RM line of PSUs for 2019 with a view of making them appeal to a broader section of enthusiasts. Chief amongst the differences/improvements is Windows Modern Standby certification, increased warranty that now lasts 10 years, and removal of Corsair Link compatibility.

The new 80 PLUS Gold-rated RMs, which we'll call the 2019 editions, are available in 650W (£80), 750W (£90), and 850W (£100) capacities, and we have the largest-capacity model in for evaluation today.
