Power for ATX 3.1 builds

This 850W ATX 3.1 power supply targets builders who need PCIe 5.0 readiness and full modular cabling. It suits high-performance desktops that draw substantial power from a single 12V rail. Buyers who want more storage or additional graphics cards will need a higher-capacity unit.

Thermals, noise and power draw

A 120 mm fluid dynamic bearing fan handles cooling across the load range. Active PFC and 100-240 V auto-switching keep input current stable. Cybenetics Platinum and 80 PLUS Gold ratings confirm 87% efficiency at 20% and 100% load, rising to 90% at 50% load.

Build quality and daily connectivity

Full modular design uses ribbon cables for easier routing inside compact cases. The 140 mm chassis depth fits most ATX layouts. Native 12V-2x6 cables with dual 8-pin to 16-pin adapters support modern GPUs without extra adapters.

Questions about this item

How do I route the 12V-2x6 cable through a case with a 140 mm PSU limit?

The unit is 140 mm long, so verify the case clearance before installing the native 12V-2x6 cable; the fully modular ribbon cables let you connect only what you need and keep the routing clean.

When should I expect to replace the 120 mm Fluid Dynamic Bearing fan?

Fluid Dynamic Bearing fans typically run for many years; listen for increased noise or vibration as the first sign that the fan may need service.

At what load does the 87 percent efficiency floor apply during sustained operation?

The 87 percent efficiency rating is measured at both 20 percent and 100 percent of the 850 W rated load, so prolonged full-load use stays at or above that floor.
