- ກະກຽມລະບົບຂອງທ່ານ: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your PC case according to its manufacturer's instructions.
- ຖອດແຫຼ່ງຈ່າຍໄຟເກົ່າອອກ (ຖ້າມີ): Disconnect all cables from your old power supply to the motherboard, graphics card, and other components. Unscrew and remove the old power supply from the case.
- Install New Power Supply: Carefully place the Mars Gaming MPB750SI into the power supply bay of your PC case. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards if there's a bottom vent, or upwards if not). Secure the power supply with the provided mounting screws.
- ເຊື່ອມຕໍ່ສາຍ:
- ພະລັງງານຂອງເມນບອດ: Connect the 24-pin ATX connector to your motherboard.
- ພະລັງງານ CPU: Connect the 4+4-pin EPS +12V connector(s) to your motherboard's CPU power socket(s).
- ພະລັງງານກາດກາດ: Connect the 6+2-pin PCIe connectors to your graphics card(s) as required.
- ອຸປະກອນຕໍ່ພ່ວງ: Connect SATA connectors to SSDs, HDDs, and optical drives. Use Molex connectors for other compatible peripherals.
The MPB750SI features extra-long black flat cables, designed to facilitate clean and professional cable management within any chassis type.
- ການຄຸ້ມຄອງສາຍໄຟ: Route cables neatly to improve airflow and aesthetics. Use cable ties if necessary.
- ປິດເຄສ ແລະ ເຊື່ອມຕໍ່ໄຟ: Close your PC case. Connect the AC power cord to the power supply and then to a wall outlet or surge protector.
