SUN U45 U25 U40 compatible 1000W ATX power supply

This 1000W ATX power supply is built for SUN U45 U25 U40 systems using part numbers 300-1800-02 300-1800-03 and API4FS35-470G. Each unit is test working before dispatch and offers good quality for replacement or upgrade scenarios. It targets administrators maintaining these specific server platforms.

1000W capacity for multi-processor SUN workloads

The 1000W rating delivers headroom for dual CPU configurations and multiple drive arrays typical of U45 U25 U40 chassis. It runs out when the platform demands redundant supply pairs or hot-swap modules beyond a single fixed unit. Builders needing N+1 redundancy or higher-wattage 1800W variants should look elsewhere.
