This specific model offers full compatibility with current and future hardware. It includes both a native PCIe 5.1 12-pin connector and standard 6+2-pin cables. In practice, this means you can power new GPUs without awkward adapters. The fully modular design simplifies cable management. Also, the semi-passive 120mm fan ensures quiet operation.

ATX 3.1 and PCIe 5.1 Compatibility

This PSU is natively compliant with the ATX 3.1 and PCIe 5.1 standards. It supports the 12VHPWR connector for high-end graphics cards. You do not need adapters for next-gen GPUs. The unit can handle power excursions up to 720W (peak). This ensures stability during intensive gaming or rendering tasks. It is built for the latest hardware releases.

Silent Operation with Semi-Passive Cooling

The 120mm fan uses a Rifle bearing for low noise and long life. Its speed ranges from 0 to 1800 RPM. At low loads, the fan stops completely for silent operation. The noise level is rated at just 30.2 dB. This makes it ideal for quiet office builds or media centres. Active cooling engages only when necessary.

High Efficiency and Stable Power

With 80 PLUS Gold certification, this unit achieves 92.8% efficiency. It features Active PFC (Power Factor Correction) with a 0.98 rating. This reduces energy waste and improves power quality. The single +12V rail provides 54.1A, ensuring consistent power to your CPU and GPU. It is designed for continuous operation with a 100,000-hour MTBF.

Comprehensive Protection Features

Your components are protected by a full suite of safety features. These include Over Current, Over Power, and Over Voltage protection. It also has Overheating, Short Circuit, and Surge & Inrush protection. Under Voltage protection is included as well. This safeguards your investment against electrical faults. The unit holds power for 22.5ms during interruptions.

Fully Modular Cable Management

The fully modular cabling allows you to connect only what you need. This reduces clutter and improves airflow inside your case. The motherboard power cable is 55cm long. The CPU power cable is 65cm long for easy routing. SATA and Molex cables offer flexible drive connections. Cable ties are included for neat installation.
