Product information

Description

The Mars Gaming MPB850SI Power Supply Unit is an 850 W desktop computer power supply designed to deliver reliable energy performance and stable operation for modern PC builds. Featuring an ATX form factor, a 24-pin ATX motherboard connector, and 80 PLUS Bronze certification, this non-modular power supply operates on an AC input voltage of 200 to 240 V. It is equipped with active cooling utilizing a 12 cm fan and complies with CE and RoHS standards to ensure safety during daily operation.

Advantages

This power supply unit offers high energy efficiency supported by its 80 PLUS Bronze rating, helping to reduce power consumption while maintaining optimal operating temperatures. The active cooling system features a 12 cm fan that effectively dissipates heat from internal components. Its standard ATX form factor ensures broad compatibility with various desktop computer cases, while the inclusion of essential power connectors provides reliable power delivery to system components.

Suitable for

  • Building custom desktop personal computers
  • Powering standard office and home PC configurations
  • Replacing older or failing power supply units in ATX cases
  • Budget-conscious system upgrades requiring 850 W of power

When it may not be suitable

This power supply may not be suitable for advanced builds that require fully modular cabling for tight space management in compact chassis. Additionally, systems with extremely high power demands exceeding 850 W or specialized industrial servers will require a different power unit specification.

How to use

To install the power supply unit, ensure your computer system is powered off and disconnected from the electrical outlet. Mount the unit securely into the compatible ATX case using standard screws. Connect the 24-pin ATX cable to the motherboard and attach the necessary peripheral and component connectors according to your hardware layout. Verify all connections are secure before restoring power to the system.

What to consider before purchase

  • Verify that your computer case supports the standard ATX power supply form factor

  • Confirm that non-modular cabling fits your cable management preferences
  • Ensure your local electrical supply matches the required AC input voltage of 200 to 240 V
