Power Supply Unit for Dell PowerEdge R630 R730 T430 T630 — 495W, compatible with part 0TH1CT-RFB

Replacement 495W power supply unit designed for Dell PowerEdge R630, R730, T430 and T630 servers. This server power supply delivers up to 495 watts of output to support boot, system operation and moderate server loads. It is intended as a field-replaceable spare for routine maintenance or rapid restoration of power redundancy in rack and tower PowerEdge systems.

Advantages

The unit provides a compact, hot-pluggable power solution that helps restore or maintain server uptime. Engineered for compatibility with the listed PowerEdge models, it supports standard server power-management features and provides stable voltage regulation under normal operating conditions. Its form factor and connector type match the server chassis expectations, allowing straightforward installation during service windows.

Suitable for

• On-site replacement of a failed or failing power supply in Dell PowerEdge R630, R730, T430 and T630 servers
• Maintaining or restoring N+1 or N+2 power redundancy in data center and rack environments
• Keeping spare parts inventory for IT maintenance, repair and operations (MRO)
• Server refurbishing or rebuild projects that require original-style power modules

When it may not be suitable

This 495W unit is intended for the specific PowerEdge models listed and may not provide sufficient capacity for heavily populated, high-power configurations or servers fitted with multiple power-hungry expansion cards. It should not be used as a substitute for higher-wattage modules where the server configuration or workload demands exceed 495 watts.

Key specifications

• Output power: 495 W nominal
• Form factor: hot-pluggable server power supply module
• Compatibility: designed for Dell PowerEdge R630, R730, T430, T630 chassis
• Input: AC mains input with server-specific inlet and connector (matching Dell chassis)
• Cooling: internal fan-assisted cooling compatible with server airflow design

How to use

Install the unit into the server while the system is either powered with redundant supplies or following proper shutdown procedures if only a single supply is present. Slide the module into the designated power bay until it seats and the retention latch engages, then connect the AC mains cable to the server inlet. If replacing an existing unit, remove the failed module by disengaging the retention latch and pulling the module straight out. Verify that the server recognizes the new power supply through the system management interface and monitor for normal fan operation and stable power indicators.

What to consider before purchase

• Confirm physical compatibility with your server chassis model and available power bay type
• Check total system power requirements to ensure 495 W is sufficient for your configuration
• Consider whether you require a single spare or additional redundancy (N+1/N+2) in your rack
• Verify warranty, return policy and condition (new, refurbished, or tested spare) with the seller

Usage recommendations

Use this power supply as a direct replacement in compatible PowerEdge servers and maintain it as part of a spare-parts program. Prioritize installation into systems with redundant supplies when hot-swapping to avoid interruption. Observe electrostatic discharge precautions and ensure firmware and management controllers are up to date to properly report power-module status.
