- SATA эрчим хүч: SATA тэжээлийн кабелийг SSD, HDD болон оптик хөтчүүддээ холбоно уу.
- Peripheral Power (Molex): Connect peripheral power cables for case fans, fan controllers, or other accessories that use Molex connectors.
- Кабелийн менежмент: Route cables neatly to improve airflow and aesthetics within your case.
5. Ашиглалтын заавар
Once all components are connected and secured, you can power on your system.
- Хувьсах гүйдлийн хүчийг холбоно уу: Plug the AC power cord into the power supply's inlet and then into a wall outlet or surge protector.
- Цахилгаан тэжээлийн хангамж: Flip the power switch on the back of the power supply to the "ON" (I) position.

5.1. Сэнсний ажиллагаа (Хагас сэнсгүй горим)
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.
