Power rating and continuous output

This power supply is rated for 800 W continuous power with a 1000 W maximum peak. It follows the ATX 12V v2.3 and EPS 12V standards and carries 80 PLUS certification for efficiency above 80 percent. Active PFC corrects the power factor across a 115 V or 230 V input range. A single fan provides cooling while keeping noise low.

Multi-GPU builders versus modular-cable preference

The unit includes four 6+2 pin PCI-Express connectors and is SLI certified, making it suitable for systems with multiple graphics cards. It also supplies a 20+4 pin ATX connector, two +12 V rails and full voltage coverage from 110 V to 240 V. Builders who want detachable cables for easier cable management should consider a modular design instead.

Non-modular cabling as the deciding factor

All cables are fixed to the unit, so every connector occupies space inside the case whether it is used or not. This affects airflow and tidiness in compact builds. If a fully modular or semi-modular layout is required for the build, this model will not meet that need.
