Montech GAMMA 3 Spec and Price in the United Kingdom
80 Plus Gold850WATX
GAMMA 3 is Montech's mainstream gold line, a tier below the platinum TITAN PLA: 80 PLUS Gold with a stated 91.9% average efficiency, ATX 3.1 and PCIe 5.1, and a native 12V-2x6 cable so a current graphics card needs no adapter. The chassis is only 140mm deep — easy to fit under a mid-tower shroud — and one 135mm sleeve-bearing fan cools all three wattages, 650W, 750W and 850W. Montech covers it for five years and excludes mining from that.
