Lenovo 4P57A72666 power supply unit 1100 W

Product Overview

AI-generated summary

If you’re running a Lenovo server that calls for this specific 1100W PSU, this is a sensible buy. The big selling point isn’t “more watts for the sake of it” — it’s compatibility and reliability in a production environment, where the cost of downtime dwarfs the price of the unit. £216 ex-VAT is reasonable for a genuine Lenovo replacement, especially if you’re looking to keep spares on-site or replace a failing supply without playing parts-matching games.

That said, I wouldn’t buy it “just because it’s 1100W” for a random system. Power supplies are picky: the right model/FRU matters, along with the server’s power and backplane design. If your current PSU is the wrong type (or you’re unsure what the chassis expects), you can waste time and still end up with the wrong hardware. So: buy it if you already have a Lenovo platform that explicitly supports this PSU; skip it if you don’t have a clear match, and instead confirm the exact part your server takes.
