How to use
Before installation, disconnect the computer from mains power and discharge static by grounding yourself. Remove the chassis cover and locate the existing power supply.

Reconnect the fixed cables to the motherboard and devices according to the original layout, replace the chassis cover, and reconnect mains power. Power on the system and verify stable operation and correct voltages in the BIOS or system monitoring tools.
