Replacement 495W power supply unit compatible with Dell PowerEdge R630, R730, T430 and T630 servers. This PSU is intended to restore or maintain reliable power delivery in rack or tower configurations and provide stable 495 watts output under normal operating conditions. The unit is suitable for use as a spare, during server maintenance, or for upgrading an existing power module to ensure continued operation in data center and enterprise environments.

Advantages

This power supply delivers a rated 495W output and is built to meet the thermal and electrical requirements of supported Dell PowerEdge models. It offers a compact form factor designed to fit the designated power bay for the listed servers and supports standard server power management and hot-swap capabilities where the server chassis allows. Using a compatible replacement PSU reduces downtime by restoring expected power capacity and helps maintain redundancy in multi-PSU configurations.

Suitable for

• Replacing a failed or underperforming power supply in Dell PowerEdge R630, R730, T430, T630
• Keeping as a spare for service and maintenance in data centers or branch IT rooms
• Restoring full power capacity in servers used for virtualization, database, or web hosting workloads
• Maintaining redundant power configurations in multi-PSU server setups

When it may not be suitable

This unit is specifically designed for the listed Dell PowerEdge models and may not be mechanically or electrically compatible with other server models or generic chassis. It is sized for systems requiring up to 495W; for servers with higher power demands or heavily upgraded configurations, a higher-capacity PSU or additional units may be required.

Key specifications

• Rated output power: 495 watts
• Form factor: server hot-pluggable / rack/tower compatible power module (fits designated Dell PowerEdge bays)
• Input: standard AC mains for data center/server use (voltage and frequency per server requirements)
• Cooling: integrated fan(s) designed for server chassis airflow
• Compatibility: designed for Dell PowerEdge R630, R730, T430, T630 server models

How to use

Power down the server or follow the server vendor’s recommended hot-swap procedure if the chassis and operating state permit. Remove the failed unit by releasing the securing latch and sliding the module from its bay. Insert the replacement 495W module until it seats and the securing latch engages. Restore AC power and verify the server reports the new power supply as present and operating through system management tools or front-panel indicators. Observe appropriate electrostatic discharge (ESD) precautions and ensure the server is placed on a stable power source and properly grounded.

What to consider before purchase

• Confirm mechanical and electrical compatibility with your specific Dell PowerEdge server model and chassis revision
• Verify that 495W is sufficient for your server configuration and planned workloads
• Check whether your environment requires redundant PSUs and acquire additional units accordingly
• Ensure connector type and hot-swap capability match your server’s requirements

Usage recommendations

Install the PSU following Dell’s service documentation and perform a validation check using system management tools. Keep a tested spare unit on hand for critical systems and monitor power supply status via onboard diagnostics to detect early signs of degradation.
