ATX 3.1 850W Fully Modular Unit

This 850W ATX 3.1 power supply targets high-performance gaming PCs and content creation workstations. Its fully modular cabling lets builders connect only the cables required for a clean interior. The unit carries Cybenetics Gold certification for verified efficiency and noise levels.

Cybenetics Gold Thermals and 140mm FDB Fan

A 140mm fluid-dynamic-bearing fan runs in ECO mode under 40 percent load for silent operation. Cybenetics Gold coverage confirms high efficiency with minimal noise across typical workloads. Active PFC and a single +12V rail deliver stable power with hold-up time exceeding 12ms at full load.

12VHPWR 16-Pin Connector for PCIe 5.1 Graphics

The native 12VHPWR 16-pin connector supplies up to 600W to PCIe 5.1 graphics cards including RTX 40 and 50 series. This single specification decides whether the unit matches a modern GPU without adapters. Japanese capacitors and full protection circuits back the connection.

Questions about this item

How do I install the 12VHPWR 16-pin connector and what step do builders often miss?

Plug the 16-pin cable fully until the latch clicks; the step many miss is seating all twelve power pins and four sense pins evenly so the GPU detects 600 W capability.

What maintenance will the 140 mm FDB fan need after long use?

The fluid-dynamic bearing is sealed for life; only occasional dust removal with compressed air is required to keep airflow steady.

At what load does the fan spin up and become the first audible limit?

The ECO mode keeps the fan stopped until roughly 40 % load, after which the 140 mm FDB fan ramps up and becomes the first noticeable noise source.
