IBM - 00YL556 - System x 750W High Efficiency Platinum AC PSU

IBM 00YL556 System x 750W High Efficiency Platinum AC PSU

The IBM 00YL556 is a 750W High Efficiency Platinum-rated AC power supply unit for IBM System x server platforms, built to support stable power delivery in 24/7 rack environments. It is a practical spare for maintaining power redundancy and predictable operation during PSU failures or planned maintenance.

This PSU is commonly deployed in IBM x86 infrastructures where consistent power delivery and efficient operation matter in dense racks. For broader platform sourcing and lifecycle support across your server estate, align this spare with other IBM components used in System x deployments, and plan capacity changes alongside CPU and MEMORY upgrades.

Key Features

Key technical characteristics and deployment benefits for this IBM System x power supply:

• 750W AC power output to support typical System x configurations with multiple CPUs, memory, and storage devices.
• High Efficiency Platinum-rated design to help reduce power draw and heat output in dense rack environments.
• Compatibility with IBM System x server families, including examples such as select x3500, x3550, x3650 and related System x models that use 750W Platinum AC PSUs, to simplify maintenance planning and standardise spares.
• Hot-swap capable PSU design (platform-dependent) to support serviceability and reduced maintenance windows in redundant power configurations.
• Designed for redundant PSU setups (when supported by the chassis) to help maintain uptime during a single PSU failure.
• Enterprise-grade power regulation and protection features to support stable operation under varying workload and thermal conditions.
• AC input PSU form factor intended for rack server chassis integration to keep cabling and airflow management consistent.
• Suitable for 24/7 operation in production environments to support continuous compute services and virtualisation hosts.

Refurbished Quality and Warranty

This unit is refurbished hardware, typically cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Choosing refurbished spares is a practical way to extend the lifecycle of existing server estates, control budget compared to buying new, and reduce electronic waste.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware, shipping worldwide from Denmark.

For complete System x maintenance planning, this spare is commonly stocked for standardised RACK SERVER environments where fast replacement sourcing helps reduce operational risk.
