- Gerenciamento de cabos: Organize os cabos de forma ordenada para melhorar o fluxo de ar e a estética dentro do seu gabinete.
5. Instruções de operação
Once all components are connected and secured, you can power on your system.
- Conecte a alimentação CA: Plug the AC power cord into the power supply's inlet and then into a wall outlet or surge protector.
- Power On PSU: Flip the power switch on the back of the power supply to the "ON" (I) position.

5.1. Fan Operation (Semi-Fanless Mode)
The FSP Dagger Pro 850W features a semi-fanless design for optimized low-noise operation. The fan will remain off (0dBA) under low load conditions (typically below 20% load or <25°C internal temperature). As the load increases, the fan will gradually spin up to maintain optimal temperatures, ensuring quiet operation when not under heavy demand.
