Product information

Description

The P450B power supply is 80 PLUS Bronze certified, delivering up to 85% efficiency at 50% load to reduce wasted energy, heat and fan noise. It features a single +12V rail for stable power delivery and compatibility with a wide range of hardware, a 120mm hydraulic-bearing fan with automatic speed control for quieter operation, and reliable flat cables that reduce clutter and improve internal airflow. Multiple built-in protections help maintain system stability under varying conditions.

Advantages

The P450B combines Bronze-level efficiency with a single +12V rail design to provide stable output suitable for typical desktop and entry-level gaming builds. Flat cables improve case airflow and cable management while the hydraulic-bearing 120mm fan offers long service life and automatic speed adjustment to minimize noise. Comprehensive protection circuits (OCP, OTP, OVP, OPP, UVP, SCP) enhance system safety.

Key specifications

Certification: 80 PLUS Bronze (≈85% efficiency at 50% load)
Fan: 120mm hydraulic bearing (automatic speed control)
Rail design: Single +12V rail
Cabling: Flat cables for improved airflow and cable management
Protections: OCP, OTP, OVP, OPP, UVP, SCP

How to use

Install the P450B into a compatible ATX case, secure it with the mounting screws, and connect the motherboard, CPU and peripheral cables according to your system layout. Route the flat cables along case edges to improve airflow and avoid blocking fans. The fan speed is controlled automatically based on power/temperature, so no manual adjustment is required. Verify correct voltages and connections before powering on the system.

Recommendations

For optimal operation, use the P450B with systems that match its power rating and ensure good case ventilation. Regularly inspect cables and connections and keep dust away from the fan to maintain efficiency and reliability.
