## Long description

The Mars Gaming MPB750SI 750 W ATX power supply combines high output with energy efficiency and a focus on low noise. It is a non-modular unit with a 24-pin ATX connector and an active 120 mm fan. Certified 80 PLUS Bronze (230V EU) and developed with DC-DC and SMD technologies, the MPB750SI is designed to provide stable voltages and reliable operation for demanding PC configurations, while its AI2-RPM fan control reduces acoustic impact.
Advantages
The power supply uses a copper-aluminum core SI fan with FDB bearings and AI2-RPM intelligent control to automatically adjust fan speed according to system load, achieving a balance between cooling and near-silent operation. DC-DC conversion and SMD manufacturing improve voltage stability and component durability. Extra-long flat black cables simplify cable management and improve internal airflow. The unit includes multiple protections (OVP, UVP, OCP, OPP, SCP) and comes with a 7-year warranty, meeting TÜV Rheinland testing standards.
Suitable for
Gaming PCs with mid to high-power graphics cards
Workstations requiring stable 12V rail performance
Systems where low noise is important (home or studio)
Builds that benefit from clean cable routing and airflow
