Setup and Installation

This section outlines the general steps for replacing a power supply unit in a compatible HP SFF desktop. Specific steps may vary slightly depending on your exact computer model. Refer to your computer's service manual for detailed instructions if available.

1. Prepare the Work Area: Ensure you have a clean, well-lit, and static-free workspace. Gather necessary tools, such as a Phillips head screwdriver.

   • Disconnect all peripheral cables (monitor, keyboard, mouse, USB devices, etc.).
3. Open the Computer Case: Remove the side panel of your computer case to access the internal components. This usually involves unscrewing a few thumbscrews or standard screws on the back of the case.
4. Locate and Disconnect Old PSU:
   • Identify the existing power supply unit.
   • Carefully disconnect all power cables from the motherboard, hard drives, optical drives, and any other components. Note their locations or take pictures for reference.
   • Unscrew the mounting screws that secure the PSU to the computer chassis.
   • Gently remove the old PSU from the case.
5. Install New PSU:
   • Carefully place the new POINWER 240W PSU into the designated slot in your computer case.
   • Secure the PSU with the appropriate mounting screws.
   • Connect the power cables (P1, P2, P3, and any other necessary connectors) to their respective components. Ensure all connections are firm and correctly oriented. Refer to the image below for connector types.
6. Close the Case and Reconnect:

Operating Instructions

Once installed, the POINWER 240W Power Supply Unit operates automatically with your computer. It provides stable power to all connected components. No user intervention is typically required for its operation.

Maintenance
