Power Supply Unit Lenovo 180W TFX 00PC774

The Lenovo 180W TFX power supply is a compact replacement unit designed for systems that require a TFX form factor and 180-watt output. It delivers stable DC power for core components in small desktop PCs and workstations, enabling reliable system startup and steady operation under typical office and home workloads. The unit fits systems engineered for TFX 180W modules and is intended for use in repair or upgrade scenarios where exact physical and electrical compatibility is needed.

Advantages

This power supply offers a standard compact TFX footprint suitable for space-constrained chassis, combined with a 180W rated output to support common processor and drive configurations. It provides built-in protections and voltage regulation to maintain stable voltages for CPU, motherboard and storage devices. The design emphasizes direct replacement compatibility, minimizing the need for modifications when installed in compatible Lenovo systems.

Suitable for

• Replacement in small form-factor desktops and workstations that accept TFX power supplies
• System repairs where the original 180W TFX unit must be replaced with a physically compatible module
• Upgrades that require a reliable 180W power source for office computing tasks and light multimedia

Key specifications

• Form factor: TFX (thin form factor) designed for compact desktop enclosures
• Output power: 180 watts total continuous output
• Output types: multiple DC rails and standard motherboard power connectors compatible with TFX layouts
• Protection features: over-voltage, over-current and short-circuit protection for safe operation
• Cooling: internal low-profile fan or passive ventilation suited to small chassis airflow
• Physical orientation: designed for constrained internal space with specific mounting points for TFX bays

How to use

Power down the target system, disconnect the power cord and ground yourself to prevent electrostatic discharge. Remove the computer cover and locate the existing power supply; note connector positions and cable routing before disconnecting. Unscrew and extract the old TFX unit, then place the replacement into the same mounting location, align screw holes and secure the unit. Reconnect all motherboard and peripheral connectors following the original routing, replace the case cover and plug in the power cord. Power on the system and verify stable boot and voltage readings within expected ranges.

Recommendations

Before installation, confirm physical dimensions and connector compatibility with your specific system model. Use only in systems designed for TFX 180W modules, and ensure the chassis provides adequate airflow. If unsure about compatibility or installation, consult a certified technician or the system manufacturer’s service documentation.
