Kuasa SATA: Sambungkan kabel kuasa SATA ke SSD, HDD dan pemacu optik anda.
Peripheral Power (Molex): Connect peripheral power cables for case fans, fan controllers, or other accessories that use Molex connectors.
Pengurusan Kabel: Halakan kabel dengan kemas untuk meningkatkan aliran udara dan estetika dalam kes anda.

5. Arahan Operasi

Once all components are connected and secured, you can power on your system.

Sambungkan Kuasa AC: 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.
Sistem Hidupkan Kuasa: Tekan butang kuasa pada sarung komputer anda.

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.
