Product information

Description

The ENERMAX EMP550W is a 550 W non-modular ATX power supply designed for desktop PCs. It supports a 20+4 pin ATX motherboard connector and operates on 200–240 V AC at 50/60 Hz. The unit is 80 PLUS 230V EU certified and includes a 120 mm cooling fan in a compact black housing.

Advantages

This power supply meets the 80 PLUS 230V EU standard, delivering up to 85% efficiency at 50% load. It uses a Japanese primary capacitor to improve component lifespan and is built with comprehensive industrial-grade protection circuitry to safeguard connected components. Non-modular mesh-sleeved cables simplify cable management while improving airflow and interior appearance. The unit is ErP-ready with standby power consumption below 0.5 W when used with compatible motherboards.

Suitable for

Entry-level and mid-range desktop gaming PCs
Home and office desktop systems requiring reliable 550 W power
PC builds where compact PSU size and tidy cable routing are important

How to use

Install the ENERMAX EMP550W into a compatible ATX case, align and secure the unit with screws, then connect the 20+4 pin ATX cable to the motherboard. Attach the necessary peripheral and CPU power connectors from the PSU to the system components. Ensure the input voltage selector (if present) and mains wiring match the local supply and that the case offers adequate ventilation for the 120 mm fan.

Usage recommendations

For stable operation, use this 550 W PSU with systems whose total power draw stays below the rated output, and allow clearance for airflow around the PSU. When building or upgrading, verify connector compatibility and enable ErP settings on compatible motherboards to achieve low standby consumption.
