Key Specifications

Native PCIe 5.1 Power Delivery

This PSU includes a native 12V-2×6 connector. It supports the latest PCIe 5.1 graphics cards directly. This eliminates the need for awkward adapters. The connector is dual-colour designed for 450W output. This ensures a secure and correct connection for high-power GPUs.

Efficient Cooling and airflow

The unit uses a 120mm golf-cutter fan. This fan design moves air efficiently across the internal components. It helps maintain low operating temperatures under load. A cooler PSU generally operates more quietly and lasts longer. This contributes to system stability.

80 Plus Bronze Efficiency

ASRock rates this unit at 80 Plus Bronze certification. This means it converts AC power to DC power with good efficiency. Less energy is wasted as heat. This can lead to lower electricity costs over time. It also reduces the thermal load inside your PC case.

Built-in 5V BOOST Function

The PSU features a built-in 5V BOOST function. This provides a temporary power spike to the 5V rail. It can help with system stability during heavy transient loads. This is a useful feature for demanding components. However, you should verify specific motherboard compatibility if this is critical.

Reliable 5-Year Warranty

ASRock backs this power supply with a reliable 5-year warranty. This offers long-term peace of mind for your investment. It indicates the manufacturer’s confidence in the product’s durability. Always register your product if required by the manufacturer.
