- Cable de placa base ATX de 24 pins: Connecteu-lo al connector d'alimentació principal de la placa base.
- 8-pin (4+4) CPU Power Cable(s): Connect to your motherboard's CPU power connector(s).
- PCIe 5.1 12VHPWR (16-pin) or 8-pin (6+2) PCIe Cables: Connect to your graphics card(s) as required.
- Cables d'alimentació SATA: Connect to SSDs, HDDs, and optical drives.
- Cables Molex: Connect to any peripherals requiring Molex power.
- Gestió de cables: Route cables neatly behind the motherboard tray or in designated cable management areas to improve airflow and aesthetics.
- Tanqueu la caixa i connecteu l'alimentació: Once all connections are secure, close your computer case. Plug the AC power cord into the PSU and then into a grounded wall outlet.
