Product information

Description

The Mars Gaming MPB850SI 850 W power supply combines high output, energy efficiency and very low acoustic emissions for desktop PCs. Designed as a non-modular ATX unit, it delivers stable 850 W total power through a 24-pin motherboard connector and multiple peripheral cables. The model features a 120 mm SI fan with fluid dynamic bearings and an AI2-RPM intelligent control system, DC-DC conversion and SMD components to ensure reliable voltage regulation and long-term durability.

Advantages

The MPB850SI provides 80 PLUS Bronze 230V EU efficiency, TÜV Rheinland compliance and multiple built-in protections (OVP, UVP, OCP, OPP, SCP) for safe operation. Its SI fan with copper and aluminum core and FDB bearings reduces friction and noise while improving lifespan. AI2-RPM automatic fan-speed control optimizes cooling according to load, and extra-long flat black cables facilitate clean cable management and improved internal airflow.

Suitable for

Gaming desktops with mid to high-end graphics cards
Workstations requiring stable 12V rails and DC-DC regulation
Systems where quiet operation and efficient cooling are important

How to use

Install the MPB850SI into a compatible ATX case following standard safety precautions: power off and unplug the system, mount the PSU in the designated bay and secure with screws, connect the 24-pin ATX cable to the motherboard and attach peripheral and PCIe cables to drives and graphics cards as required.

For stable, quiet operation keep the PC case ventilated and free of dust. Use the MPB850SI with systems that match its 200–240 V input range and ensure total system power draw remains within the 850 W rating.
