## Long description

The Mars Gaming MPB750SI 750 W power supply unit delivers stable 750 W output for desktop PCs. This ATX, non-modular PSU features a 24-pin motherboard connector, 120 mm SI fan with copper and aluminium core and FDB bearings, and 80 PLUS Bronze 230V EU certification. Designed with DC-DC and SMD technologies and AI2-RPM intelligent fan control, the MPB750SI balances energy efficiency and quiet operation while offering advanced electrical protections and a 7-year warranty.
Advantages
The MPB750SI combines high efficiency (80 PLUS Bronze) and DC-DC conversion for stable voltages and lower energy consumption. Its SI fan with FDB bearings and AI2-RPM adaptive control reduces noise while maintaining adequate cooling. Comprehensive protection features (OVP, UVP, OCP, OPP, SCP) and TÜV certification contribute to long-term reliability and safety. Extra-long flat black cables simplify cable management and improve internal airflow.
Suitable for
Gaming PCs with mid to high-power graphics cards
Home and office desktops requiring reliable 24-pin ATX power
Systems prioritizing low noise and energy efficiency

How to use
Install the PSU into a compatible ATX case following the motherboard and case manufacturer instructions. Connect the 24-pin ATX cable to the motherboard and attach the required PCIe, CPU and peripheral connectors to your components. Ensure mains input matches 220–240 V and use proper grounding. During initial operation the AI2-RPM system will automatically regulate fan speed based on system load to achieve optimal balance between cooling and noise.
Usage recommendations
For best results, place the power supply with its fan intake unobstructed and maintain good case airflow. Use the MPB750SI in systems whose combined component power draw stays comfortably below 750 W to preserve efficiency and longevity. Keep dust filters clean and verify cable routing to avoid airflow blockage.
