Product information

Description

TACENS Mars Gaming MPB550SI is an ATX power supply unit with 550 W total output and 80 PLUS Bronze efficiency. It provides active PFC and overpower protection, fixed (non-modular) cabling including a 24-pin ATX motherboard connector, 4+4 CPU connector, one 6+2 PCIe connector, four SATA and two Molex peripheral connectors. The unit uses a top-mounted 120 mm fan for active cooling and is intended for desktop PC builds with 220–240 V AC input.

Advantages

The power supply delivers up to 550 W with approximately 90% efficiency under typical loads and includes active power factor correction to improve power quality. Its single +12V rail supplies the majority of the output power, and built-in overpower protection helps prevent damage from excessive loads. The compact ATX form factor and top 120 mm fan provide a balance of cooling performance and low noise (around 12 dB).

Suitable for

Home or office desktop PCs
Entry-level and mid-range gaming builds
Systems requiring a single +12V rail and standard peripheral connectors

Connect the 24-pin ATX cable to the motherboard, attach the 4+4 CPU connector to the CPU power header, and plug the PCIe, SATA and Molex connectors to your components as required.

Usage recommendations

For reliable operation, use this PSU in systems that do not exceed its 550 W rating and ensure adequate case ventilation. Regularly check connector seating and dust accumulation on the 120 mm fan; keep the PSU in a well-ventilated area and avoid blocking the fan intake to maintain efficiency and low noise.
