Slim Specifications

ATX 3.1 and PCIe 5.1 Compliance

The PSU meets ATX 3.1 guidelines. It handles power excursions common with modern GPUs. Because it includes a 16-pin PCIe cable, it supports PCIe Gen 5.1 graphics cards directly. This ensures compatibility with the latest hardware releases.

Durable Component Selection

Military-grade capacitors are used throughout the design. These components provide premium durability under sustained loads. A protective PCB coating shields against moisture and dust. This construction extends the unit’s operational lifespan significantly.

Efficient Cooling and Noise

An active cooling system uses a single ball-bearing fan. This design can last up to twice as long as sleeve bearings. The top-mounted fan location optimises airflow within the case. Active PFC improves power factor correction for stable voltage regulation.

Comprehensive Protection Features

The unit includes multiple protection circuits. These cover overcurrent, overpower, and undervoltage scenarios. Short circuit protection is also integrated. These features safeguard your components during unexpected electrical events.

Connectivity and Cabling

The PSU is fully modular, allowing you to connect only necessary cables. It provides one 20+4 pin ATX connector and a 4+4 pin CPU connector. For graphics, it offers three 6+2 pin PCIe connectors and one 16-pin connector. Storage drives connect via four SATA ports and two Molex ports.
