## Long description

The LC-Power LC420-12 V2.31 350 W is a compact desktop power supply unit designed for office and home PCs. It delivers 350 W of continuous output with 80 PLUS Bronze efficiency, active Power Factor Correction (PFC) and a standard 20+4 pin ATX motherboard connector. The unit uses non-modular cabling and a 120 mm fan to provide quiet cooling while maintaining stable voltage for common office hardware. Built with TÜV and CE certifications and a grey housing, the LC420-12 V2.31 focuses on energy efficiency and reliable everyday performance.
Advantages
The power supply achieves up to 89.48% efficiency under typical loads and reduces standby power consumption to as low as 0.21 W, helping lower overall energy use. A 120 mm fan and a rear ventilation grille provide effective but low-noise cooling appropriate for workstations and home systems. Compliance with TÜV and CE standards ensures the unit meets recognized safety and electromagnetic requirements. The included set of office-oriented connectors covers common system configurations without unnecessary modular cabling.
Suitable for
 Small office or home desktop computers
 Basic business workstations for document editing and web browsing

How to use
Install the LC-Power LC420-12 V2.31 into a compatible ATX PC case following standard PSU mounting procedures. Connect the 20+4 pin ATX connector to the motherboard and attach the remaining fixed cables to drives and peripherals as required by your system. Ensure proper airflow by orienting the ventilation grille to allow exhaust through the case rear or to intake fresh air according to your case design. Verify all connections before powering on the system and observe basic safety precautions such as disconnecting mains power during installation.
Usage recommendations
For reliable operation, use this PSU with mainstream office components and avoid pairing it with high-power graphics cards or heavily overclocked systems that exceed the 350 W capacity. Keep case intake and exhaust unobstructed to maintain low fan noise and stable temperatures. If you plan future upgrades that increase power demands, consider a higher-wattage or modular unit to simplify cable management.
