The LC-Power LC420H-12 420W ATX 12V power supply delivers stable power for standard desktop PC builds. Designed in a compact ATX form factor, it supports common motherboard connectors and provides the necessary +12V rail for processors and graphics cards in entry-level and office systems. The unit is intended for straightforward installation in home or office computers, repair projects and system upgrades where reliable, continuous power up to 420 watts is required.

Advantages

The power supply offers a straightforward design focused on compatibility and ease of installation. It provides a single strong 12V rail to support system components and includes standard protection features to help maintain stable output under typical operating conditions. The compact ATX size allows fitting into most standard cases, minimizing space constraints in builds and upgrades.

Suitable for

• Home or office desktop PCs
• System repairs and component replacements
• Budget or entry-level gaming and multimedia builds
• Upgrading older systems to modern connectors

Key specifications

• Rated output power: 420 W
• Main rail configuration: single +12V rail
• Form factor: ATX
• Standard motherboard and peripheral connectors for typical desktop setups
• Cooling: internal fan for thermal regulation
• Protection features: overcurrent and short-circuit protection (typical for ATX supplies)

How to use

Before installation, disconnect the PC from the mains and ground yourself to prevent electrostatic discharge. Mount the power supply into the case’s ATX bracket and secure with screws. Connect the 24-pin main motherboard connector and the 4/8-pin CPU power connector as required by your motherboard. Attach peripheral power connectors to storage drives, optical drives and other devices. Double-check connections, ensure the fan intake is unobstructed, then reconnect mains power and power on the system to verify stable operation.

Recommendations

Use this 420W ATX supply in systems whose total component power draw stays comfortably below the rated output to ensure headroom for peak loads. Maintain case airflow and clean dust from the fan and vents periodically. Avoid running high-power discrete graphics cards or overclocked CPUs that exceed the supply’s recommended capacity without calculating total system power needs.
