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.

Perguntas sobre este artigo

Should I pick the 850W white model or look for a different wattage in this series?

This specific unit is the 850W white version; choose it if your build’s peak draw fits within 850W, otherwise select a higher-wattage model from the same Leadex VII XG line.

What does the 850W rating actually deliver inside a PC?

The single +12V rail can supply the full 850W continuously, with 87% efficiency at 20% load, 90% at 50% load and 87% at 100% load per 80 PLUS Gold, plus Cybenetics Platinum overall efficiency above 89% at 115V and above 91% at 230V.

How does the ATX 3.1 and PCIe 5.1 interface limit real-world use?

The PSU meets Intel ATX 3.1 and PCIe 5.1 specs, includes two native 12VHPWR cables (2x8pin-to-16pin) and three 6+2-pin PCIe connectors, so it supports modern GPUs without adapters while the 150mm length fits standard ATX cases.
