IBM 74Y8178 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y8178 is a 1400W AC power supply, a genuine IBM component for the pSeries/Power server range. It converts mains AC into the regulated DC rails the system’s processor, memory and I/O subsystems draw on, and is installed as a hot-swap unit alongside its redundant partner in eligible chassis so that a single failed supply does not take the system down. Power supplies of this rating are consumable in the sense that internal capacitors and fans degrade over years of continuous duty, making replacement a routine part of keeping an established Power deployment’s redundancy intact rather than something reserved only for outright failures. Genuine IBM units of this kind are specified rather than a generic equivalent because the host system’s power subsystem firmware expects to see a recognised IBM supply on its management bus. Specifiers should confirm their exact system model and existing power configuration before ordering, since IBM shipped several similarly-rated supplies with different connectors and firmware across the Power range. Tech-Star (UK-based, shipped worldwide) supports ongoing server maintenance projects. Get in touch with our sales team for availability and a price.
