This section details the core specifications of the unit.

ATX 3.1 and PCIe 5.1 Compliance

The PSU supports the latest ATX 3.1 standard. It handles power excursions up to 200%. This ensures stability during sudden load spikes. The unit includes two native 12V-2×6 cables. These are ready for modern graphics cards.

iCOOL Intelligent Fan Control

You can toggle the iCOOL mode via a physical switch. In iCOOL Mode ON, the fan stays off during low loads. This reduces noise and improves energy efficiency. In Mode OFF, the fan runs continuously. This provides consistent cooling for heavy workloads.

Cybenetics Lambda A Acoustic Certification

The Steel Legend series holds the Cybenetics Lambda A certification. This recognises outstanding noise control performance. It is an ideal choice for users seeking ultra-quiet operation. The 135mm Fluid Dynamic Bearing fan supports this low-noise profile.

High-Quality Component Construction

The unit uses 105°C Japanese-made capacitors. This ensures a prolonged lifespan and reliability. The fluid seal design and herringbone structure on the fan minimise noise. A full suite of protections guards your components.
