Product information

Description

The Enermax EMP650W 650W power supply delivers reliable 650W output for desktop PCs, with a 20+4 pin ATX connector and AC input of 220–240 V at 50/60 Hz. This non-modular unit features 80 PLUS Standard 230V EU certification and a 120 mm cooling fan in a compact 150 × 140 × 86 mm black housing. The PSU includes a Japanese primary capacitor, a single +12V rail and industry-grade protection circuits to help ensure long service life and component safety.

Advantages

The 80 PLUS Standard 230V EU certification ensures up to 85% efficiency at 50% load under 230 V AC, reducing wasted energy and heat. A Japanese primary capacitor improves durability and operational stability. Mesh-sleeved, non-modular cables provide a soft texture for easier cable routing and improved internal airflow. The unit meets 2013 and 2014 ErP requirements with standby power below 0.5 W when supported by an ErP-enabled motherboard.

Suitable for

Home and office desktop PCs requiring up to 650 W of continuous power
System builds that benefit from non-modular, mesh-sleeved cabling for simple cable management
Energy-conscious builds needing 80 PLUS Standard efficiency and ErP standby compliance

Key specifications

Total power: 650 W
Input voltage / frequency: 220–240 V, 50/60 Hz
Motherboard connector: 20+4 pin ATX
Certification: 80 PLUS Standard 230V EU
Fan diameter: 120 mm
Cooling: 12 cm fan
Rail topology: Single +12V rail
Protection: Built-in industry-grade protection mechanisms
Colour: Black
Dimensions: 150 × 140 × 86 mm

How to use

Install the PSU into a compatible ATX case, secure it with the supplied screws, and connect the 20+4 pin ATX connector to the motherboard. Attach required peripheral and PCIe power connectors to drives and graphics cards, taking care to route the mesh-sleeved cables to avoid obstructing airflow. Ensure mains voltage matches the PSU rating (220–240 V) and use a properly rated mains cable and surge protection where available.

Usage recommendations

For reliable operation, keep the PSU intake and exhaust areas clear of dust and obstructions, maintain case airflow with adequate intake and exhaust fans, and avoid prolonged operation near the maximum rated load. Use an ErP-compliant motherboard to achieve standby power below 0.5 W.
