HP 570451-101 1200 W server power supply

This HP 570451-101 unit delivers 1200 W of AC-to-DC power in a 1U hot-swap form factor. It is built for rack-mount servers that require redundant, front-accessible power modules. The 570451-101 fits standard 1U bays and supports tool-less replacement during operation. It suits administrators who need a direct replacement for an existing HP 570451-101 module.

Sustained-load behaviour of the 1200 W module

Under continuous demand the supply maintains its rated 1200 W output within the thermal limits of a 1U chassis. Hot-swap capability allows a failed module to be exchanged without shutting down the server, preserving uptime during prolonged workloads. The unit is not intended for desktop ATX cases or non-redundant single-supply builds. Buyers who need a different wattage rating or a non-hot-swap form factor should select another model.

Questions about this item

How much heat and noise does the 570451-101 produce when running at full 1200 W load all day?

The 1200 W unit uses a 1U hot-swap form factor with internal fans designed for server airflow; expect noticeable fan noise and significant exhaust heat under continuous maximum load.

What server chassis or backplane must I already have for the 570451-101 to connect and power on?

You need a compatible HP server chassis that accepts 1U hot-swap power supplies with the matching 570451-101 connector and backplane pin-out.
