Super Flower Leadex VII XG 850W White power supply SF-850F14XG (WH)

850 W ATX 3.1 power supply

The Leadex VII XG 850 W is a white full-modular ATX 3.1 unit built for modern desktop builds. It delivers a single +12 V rail rated at 850 W and includes a native 12VHPWR cable alongside three 6+2-pin PCIe connectors. Twelve SATA power connectors support multiple drives. A 140 mm fluid dynamic bearing fan provides cooling.

ATX 3.1 and PCIe 5.1 limits

The unit meets the Intel ATX 3.1 specification and is PCIe 5.1 ready, allowing it to handle transient power spikes from current graphics cards. Efficiency reaches 87 % at 20 % load, 90 % at 50 % load and 87 % at full load under the 80 PLUS Gold programme. Cybenetics Platinum certification confirms 89–91 % overall efficiency at 115 V input and 91–93 % at 230 V input. Active PFC operates across 100–240 V.

Capacity headroom for high-end systems

With 850 W on a single rail the supply comfortably powers a high-end GPU and CPU combination plus storage and peripherals. The 12VHPWR cable and three 6+2-pin connectors give enough PCIe headers for most dual-GPU or single-flagship configurations. Twelve SATA connectors leave headroom for several SSDs and HDDs. Full modular cabling keeps unused leads out of the case.
