850 W ATX 3.1 Power Supply

This fully modular 850 W unit meets ATX 3.1 and PCIe 5.1 specifications. It uses a single +12 V rail and a 140 mm FDB fan. Japanese capacitors and Cybenetics Gold certification support high efficiency and low noise. The compact 150 mm depth fits most cases.

Suits high-performance PCs and compact silent builds

Ideal for systems with RTX 40 or 50 series graphics cards that draw up to 600 W through the 12V-2x6 connector. Builders who need multiple PCIe or SATA connections should check the cable count before choosing this model.

850 W capacity with 600 W GPU headroom

The 12V-2x6 connector delivers 600 W to a single graphics card. One 6+2-pin PCIe and two SATA power connectors cover basic storage and peripherals. Heavy multi-GPU or many-drive configurations will exceed the provided cables.

Questions about this item

What motherboard connector does the HAT-850yzB1G need to power the board?

The unit ships with a standard 24Pin ATX main connector that plugs directly into any ATX motherboard.

Will the included 12VHPWR 16pin cable work with an older GPU that only has 6+2-pin sockets?

The PSU provides one native 6+2-pin PCIe connector; for older cards you would use that cable instead of the 12VHPWR lead.

How can I confirm the fan is running in ECO mode after the build is complete?

The 140 mm FDB fan stays off below 40 % load, so silence at idle or light desktop use means ECO mode is active.
