Key Specs

Efficient Power Delivery for Stable Performance

The ASUS Prime -650B-BLACK power supply unit is built around efficiency. Its 80+ Bronze certification means it converts at least 85% of AC power to DC, reducing waste heat and lowering electricity costs. The active Power Factor Correction (PFC) ensures clean, stable voltage delivery to all components. With a combined +12V output of 648 W, this PSU can comfortably handle modern CPUs and GPUs in a single high-performance system.

Quiet Operation with Dual Ball Bearing Fan

Noise can be a major distraction during long gaming or work sessions. This PSU uses a 13.5 cm fan with dual ball bearing technology, which provides smoother rotation and longer lifespan than sleeve bearings. The active cooling system adjusts fan speed based on temperature, keeping your system cool without unnecessary noise. With a Mean Time Between Failures (MTBF) of 120,000 hours, you can expect years of quiet, reliable operation.

Comprehensive Protection for System Safety

Power irregularities can damage expensive components. The ASUS Prime -650B-BLACK includes multiple protection features: over current, over power, over voltage, overheating, short circuit, and under voltage protection. These safeguards monitor and respond to electrical anomalies instantly, preventing damage to your motherboard, CPU, GPU, and storage devices. The 6-year warranty reflects ASUS’s confidence in this PSU’s durability and protection capabilities.

Flexible Cable Configuration for Easy Installation

This non-modular PSU comes with all necessary cables pre-attached, including ATX motherboard connector, CPU power, PCIe for graphics cards, SATA for storage, and Molex for peripherals. Cable lengths are generous: SATA and Molex cables at 120/400 mm, PCIe at 60 cm, and CPU at 80 cm. The etched cables are colour-coded for easy identification during installation. The compact ATX form factor (150 x 150 x 86 mm) fits standard PC cases without clearance issues.
