## Long 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
