Product information

Description

The Mars Gaming MPB650SI Extreme Silence Power Supply is a 650 W ATX unit designed for desktop PCs that require efficient, quiet operation. It delivers stable power through a 24-pin ATX connector and supports AC input of 220–240 V (47–63 Hz). The PSU is 80 PLUS Bronze certified and built with DC-DC and SMD technologies for improved energy conversion and durability. It includes a 120 mm SI fan with a copper and aluminium core and FDB bearings, and is available in black or white. The unit is TÜV Rheinland certified, CE and RoHS compliant, and comes with a 7-year warranty.

Advantages

The MPB650SI combines high efficiency (80 PLUS Bronze) and advanced internal design (DC-DC conversion and SMD components) to offer reliable voltage regulation and reduced energy losses. Its SI fan with copper/aluminium core and FDB bearings, controlled by AI2-RPM intelligent speed management, provides very low noise levels while maintaining adequate cooling. Comprehensive protection features (OVP, UVP, OCP, OPP, SCP) and TÜV certification increase system safety and long-term reliability. Flat, extra-long black cables simplify routing and improve airflow inside the case.

Suitable for

Home and office desktop PCs requiring a quiet 650 W PSU
Mainstream gaming systems with single high-power graphics cards
Upgrades where 80 PLUS Bronze efficiency and stable 12V rail output are needed
Builds that benefit from long flat cables for better cable management

How to use

Install the MPB650SI into a compatible ATX case and connect the 24-pin ATX cable to the motherboard. Attach the necessary PCIe, SATA and peripheral connectors to your components according to their power requirements. Ensure the PSU input rating (220–240 V, 47–63 Hz) matches your mains supply and secure proper case airflow to aid cooling. The AI2-RPM system adjusts fan speed automatically; no manual fan control is required.

Usage recommendations

For reliable operation, keep the PSU intake area free of dust and maintain adequate case ventilation. Use the MPB650SI in systems within the 650 W power envelope and verify cable connections before powering on. If used in environments with unstable mains, consider additional surge protection despite the PSU’s built-in protections.
