Here are the critical specifications for this power supply unit.

Stable ATX 3.1 Compliance

This unit adheres to the ATX 3.1 standard. It handles power excursions up to 200% of its rated power. This ensures compatibility with the latest graphics cards and CPUs. However, you should verify your specific motherboard supports ATX 3.1. In practice, this standard improves transient power response. It protects your components during sudden load spikes.

Dual-Colour PCIe Cable Design

The PSU includes a native PCIe 12V-2×6 cable with a dual-colour design. ASRock Classic Green connectors show if the connection is secure. This visual cue reduces installation errors. It is particularly useful for complex builds. So, you can be confident that critical power connections are seated correctly.

High-Efficiency Cooling System

It features a 120mm silent cooling fan. This maintains low temperatures during operation. The fan helps reduce system noise. It also extends the lifespan of internal components. Because the capacitors are all Taiwanese, they offer reliable performance. This design supports the 100,000-hour MTBF rating.

Comprehensive Safety Protections

Safety is a priority with this unit. It includes a full suite of protections: OCP, SCP, OVP, UVP, OTP, and OPP. These safeguards protect your system during normal and extreme power levels. For example, OCP prevents over-current damage. This gives you peace of mind for your valuable hardware.
