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.

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.
