5. Operating Instructions

The Cooler Master V550 Gold V2 is designed for reliable and efficient operation.

Semi-Fanless Operation

This power supply features a semi-fanless mode. The 135mm Fluid Dynamic Bearing (FDB) fan remains off under low load (up to 40% of total capacity) to provide silent operation. As the load increases, the fan will automatically activate to maintain optimal temperatures.

Hybrid Switch

A hardware-based hybrid switch is located on the rear of the PSU. This switch allows you to manually toggle the semi-fanless mode on or off.

• Switch ON: Enables semi-fanless mode (fan off under low load).
• Switch OFF: Forces the fan to run continuously, regardless of load.
