HP 500W Power Supply for Proliant Servers - Reliable Replacement

Our review of the HP 500W Power Supply for Proliant servers focuses on system administrators and IT technicians who need a straightforward, compatible replacement unit. The bottom line: this is a purpose-built, no-frills internal switching power supply that delivers a firm 500W output for supported HP Proliant models, making it a practical choice when uptime and direct compatibility matter more than extras. It is ideal when a failed PSU must be swapped quickly to restore rack servers without time-consuming troubleshooting.

Key Features

• Model and part fit: The P/N 506077-001 and model HSTNS-PF01 match HP Proliant fitment for a direct swap with no adapter needed.
• Power delivery: A maximum 500W output provides stable power for a range of Proliant G6 and G7 server configurations.
• Compatibility: Explicit compatibility with DL160 G6, DL165 G6, DL165 G7 and DL320 G6 reduces risk of ordering the wrong unit for those systems.
• Switching design: The internal switching design keeps efficiency and thermal behavior appropriate for rack environments under typical loads.
• OEM form factor: The unit follows HP internal power supply standards so it fits securely in supported chassis and retains system management signaling.
• Serviceability: Straightforward replacement minimizes downtime during maintenance windows for data center or lab equipment.

Who It's For

This power supply is aimed at IT professionals maintaining HP Proliant Gen6 and Gen7 servers, small data centers, and repair shops that require an OEM-style replacement to restore a server to working order quickly. Buyers who prioritize compatibility, predictable power delivery, and a known form factor will appreciate the straightforward fit.

It is less suitable for users seeking modular, hot-swap redundant arrays with advanced monitoring beyond the server's built-in management, or for projects that demand higher than 500W continuous output. If you need an aftermarket custom-modified supply or greater wattage headroom, consider alternate solutions.
