Vetroo 850W power supply White ATX 3.1 PCIe 5.1 80 Plus Gold Full Modular

850 W ATX 3.1 power supply for high-end builds

This 850 W unit follows the ATX 3.1 and PCIe 5.1 specifications, delivering two 12+4 pin connectors plus three 8-pin PCIe connectors for modern graphics cards. Full modular cabling lets you install only the leads you need, while four SATA power connectors cover drives and peripherals. The white finish suits light-themed chassis.

Thermals, noise and power draw

A 120 mm Fluid Dynamic Bearing fan runs quietly under typical loads, and Japanese 105° C capacitors help keep internal temperatures low. 80 Plus Gold certification means efficiency exceeds 90 % at common load points, reducing waste heat and lowering electricity use. Protections include over-voltage safeguard across the 100-240 V input range.

Upgrade path and when to step up

The dual 12+4 pin connectors replace older single-connector designs, so builds moving to PCIe 5.1 graphics cards gain native support without adapters. Builders staying with PCIe 4.0 or 3.0 cards still benefit from the headroom and modular flexibility. Systems that need more than 850 W or additional PCIe connectors should consider a higher-capacity unit.
