How to use

Before installation, disconnect the system from mains power and ground yourself to prevent electrostatic discharge. Remove the chassis cover according to the desktop model’s service manual, then unplug the existing power supply cables from the motherboard and internal devices. Secure the DELL 2TXYM unit into the PSU bay using the original mounting points and fasteners, connect the main motherboard power connector and all required peripheral connectors, and ensure cables are routed to avoid obstructing fans or other components.
