850 Watt Power Supply Units

The 850 watt PSUs here range from the non-modular Ant Esports RX850, the one 80 Plus Bronze unit, to 80 Plus Gold models: the fully modular Corsair RM850x and RM850x Shift - White, the semi-modular DeepCool PN850M, the Cooler Master MWE Gold 850 V2 with ATX 3.1 and PCIe 5.1, the MSI MAG A850GN and the Ant Esports FG850 and FG850 V2. All are ATX except the Cooler Master V SFX Gold 850, a compact SFX unit with a 90-degree 12V-2x6 cable.

To choose, decide on cabling and connectors first. Fully modular units let unused cables stay out of the case. The non-modular RX850, FG850 and A850GN have every cable fixed. For a newer graphics card with a 12V-2x6 power connector, look at the ATX 3.1 or PCIe 5.1 models: MWE Gold 850 V2, V SFX Gold 850, FG850 V2 and MAG A850GN. Warranty varies widely: Corsair, DeepCool and the Cooler Master V SFX carry 10 years, MSI 7 years, the MWE Gold 850 V2 5 years and the Ant Esports units 3 years. The 80 Plus Gold and 80 Plus Bronze models have their own pages, as do the Ant Esports, Corsair and DeepCool 850 watt units.
