Virtalähde LC-Power LC6450 V2.2 450 W

450W power supply with a 120mm cooling fan and a single PCI-Express 6+2 pin connector, designed to provide stable power for compatible desktop systems. The unit includes power factor correction (PFC) and essential safety circuitry to ensure efficient energy use and protection against common electrical faults.

Advantages

The 450W rating offers sufficient capacity for many mid-range PCs while the 120mm fan provides quiet and effective cooling. The included PCI-Express V2.0 6+2 pin connector supports modern graphics cards that require auxiliary power. Built-in PFC and safety circuits improve energy efficiency and help protect connected components from overcurrent, overvoltage and short-circuit conditions.

Key specifications

• Power: 450W
• Cooling: 120mm fan
• Graphics connector: 1 × PCI-Express V2.0 6+2 pin
• Features: Power Factor Correction (PFC) and required safety circuitry

How to use

Install the power supply into a compatible desktop case following the case and motherboard manufacturer instructions. Connect the main motherboard power connector and the PCI-Express 6+2 pin connector to the graphics card if required. Ensure all connections are secure before powering on the system. Verify that the case provides adequate airflow for the 120mm fan and that the power rating matches the system’s component requirements.

Recommendations

Use this 450W power supply in systems with moderate power demands and one graphics card that can be powered by a single PCI-Express 6+2 pin connector. For higher-end builds or multi-GPU setups, consider a higher-wattage unit with additional connectors. Regularly check connectors and airflow to maintain reliable operation.
