Power for the Complete Configuration

The unit is rated for 850 W continuous output. Choose the supply around the complete system’s power requirements, including the processor, graphics card, drives and expansion hardware. The output rating describes its supply capacity; the actual power drawn by the computer depends on the installed components and the workload. Check both the power requirement and the required connectors when planning an upgrade.

80 PLUS Gold Efficiency

80 PLUS Gold certification describes the power supply’s conversion efficiency under the certification test conditions. It complements the model’s output rating when selecting a supply for the intended system. Efficiency varies with input conditions and load, so the certification should be read alongside the electrical ratings and the complete configuration rather than as a fixed efficiency at every operating point.

Connections Chosen for This Model

The fully modular cable layout lets you connect the leads required by the installed hardware and keep unused leads outside the case. The main connection set provides one 24-pin motherboard connector, two CPU power connectors, three PCIe 6+2-pin connectors, eight SATA power connectors and four peripheral connectors. Match any additional graphics-power cable with the supplied set for the unit. Use the appropriate motherboard, CPU and graphics connections for each component. Keep the PSU’s own modular cable set with the unit, and use replacement leads only when the manufacturer confirms compatibility with this exact PSU and cable interface.

Cooling That Follows the Load

A 92 mm hydraulic-bearing fan supports load- and temperature-dependent Zero RPM operation. Leave the case’s PSU intake and exhaust routes clear and position the supply according to the case guidance. Fan speed and operating noise depend on the system load, temperature and airflow around the enclosure. A low-load fan-stop mode, where provided, works as part of that control behaviour rather than guaranteeing silent operation in every workload.

Check the Case and Cable Clearance

Its SFX enclosure measures 100 × 125 × 63.5 mm. Match the PSU bay, mounting points and cable-routing space with the case before installation. Account for the connected plugs and their routing space as well as the metal enclosure itself. Arrange the cables so that the case panel can close without placing strain on the connections, and retain access to the power switch and AC inlet in the finished system.
