Motherboard Power (24-pin): Connect the 24-pin ATX cable from the PSU to the corresponding port on your motherboard. Ensure it clicks into place.
CPU Power (4+4-pin or 8-pin): Connect the CPU power cable(s) from the PSU to the CPU power connector(s) on your motherboard. High-end motherboards may require two 8-pin connectors.
PCIe Power (6+2-pin or 12VHPWR):
- For graphics cards requiring 6-pin or 8-pin PCIe connectors, use the provided 6+2-pin cables.
- For NVIDIA RTX 40 series graphics cards or other GPUs requiring the new 12VHPWR connector, use the dedicated 12VHPWR cable. Ensure it is fully seated into both the PSU and the graphics card.

כוח SATA: חבר כבלי חשמל SATA לכונני SSD, כונני HDD וכוננים אופטיים שלך.
כוח היקפי (Molex): Connect peripheral power cables for case fans, fan controllers, or other accessories that use Molex connectors.
ניהול כבלים: Route cables neatly to improve airflow and aesthetics within your case.

5. הוראות הפעלה

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

חבר מתח 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.
מערכת ההפעלה: לחץ על כפתור ההפעלה במארז המחשב שלך.

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.
