ATX 3.1 and PCIe 5.1 Ready
This power supply meets the ATX 3.1 standard. It handles power excursions up to 200%. This is critical for next-gen GPUs that demand sudden power spikes. You get a native 12V-2×6 cable for direct connection. This reduces the need for messy adapters.
iCOOL Intelligent Fan Control
The unit features a manual iCOOL switch. In ‘ON’ mode, the fan stays off during low to medium loads. This creates near-silent operation for office tasks or light browsing. The fan only spins up when temperatures or loads increase. In ‘OFF’ mode, the fan runs continuously. This provides consistent cooling for heavy gaming sessions.
Dual Colour Connectors for Safety
ASRock uses a dual-colour design on key connectors. The classic green connectors make it easy to see if a cable is fully seated. This visual cue helps prevent loose connections. It reduces the risk of poor contact and potential component damage. You can build with greater confidence.
Certified Quiet Performance
The Steel Legend series holds Cybenetics Lambda A certification. This award recognises outstanding noise control. It confirms the PSU operates very quietly under typical loads. The 135mm striped axial FDB fan contributes to this. Its herringbone structure minimises noise and maximises lifespan. For UK users who value a silent PC, this is a key benefit.
Robust Protection Suite
ASRock includes a full safety suite. Protections cover Over-Current (OCP), Short-Circuit (SCP), Over-Voltage (OVP), Under-Voltage (UVP), Over-Temperature (OTP), and Over-Power (OPP). These safeguards protect your components during normal operation and extreme power levels. The use of 105°C Japanese capacitors ensures long-term reliability.
