## Summary description

Designed to replace or upgrade existing PSUs in systems that accept ATX form factor, it ensures stable power delivery for system components.

## Long description

The ATX power supply unit Lenovo 280W 54Y8900 is a 280-watt internal PSU designed for Lenovo desktop systems that accept the ATX form factor. It supplies stable DC voltages to motherboard, processor, storage drives and peripheral devices, supporting routine system operation, repairs and upgrades. The unit is intended as a direct replacement or upgrade when the system requires a 280W Lenovo-compatible power source and fits the existing chassis mounting and connector layout.
Advantages
This Lenovo ATX power supply offers a defined 280W continuous output to maintain stable system performance under typical desktop loads. It is engineered for compatibility with Lenovo desktops that use standardized ATX mounting and connectors, reducing installation complexity. Built-in protections for overcurrent and short-circuit conditions help safeguard components. The compact internal design makes it suitable for systems with limited space while providing the necessary rails and connectors for common motherboard and drive configurations.
Suitable for
Replacing a failed or failing power supply in compatible Lenovo desktops
Upgrading an older unit to a stable 280W power source
System maintenance, repair workshops and service centers
Building or refurbishing office and home desktop systems that accept ATX PSUs
Key specifications
Form factor: ATX internal power supply
Rated output power: 280 watts
Output voltages: standard ATX rails (including +12V, +5V, +3.3V)
Protections: overcurrent and short-circuit protection
Physical design: compact internal housing suitable for compatible Lenovo chassis
Connectors: main motherboard power connector and standard peripheral/drive connectors for typical desktop configurations
How to use
Power down the desktop, disconnect it from mains power and open the case following the manufacturer’s service instructions. Remove the existing power supply by disconnecting all motherboard and peripheral connectors, and unscrewing the mounting screws. Install the Lenovo 280W ATX unit into the same mounting position, secure it with screws, and reconnect the main motherboard power connector and drive/peripheral cables to their matching ports. Close the case, reconnect mains power and perform a basic POST check to confirm stable operation.
Usage recommendations
Verify chassis compatibility and connector availability before installation. Use anti-static precautions when handling internal components and ensure adequate case ventilation to maintain operating temperatures. For systems with high-power graphics or many peripherals, confirm that 280W is sufficient for peak load; otherwise select a higher-capacity PSU. If uncertain, consult Lenovo service documentation or a qualified technician.
