Lenovo PX12-400R/450R SC PSU 4N60A033903 | Server Power Supply, NAS

Keep supported Lenovo NAS systems running with a replacement power supply built for exact-fit compatibility. The PX12-400R/450R SC is intended for select IdeaPad and IdeaCentre configurations, giving procurement teams and service desks a direct replacement path when original hardware needs to be restored. For environments where a mismatched PSU can delay recovery, this Lenovo part helps reduce guesswork. It is suited to systems that depend on consistent power delivery for shared storage, media libraries, and small-office workloads. That makes it a practical choice when the cost of downtime outweighs the price of a verified OEM replacement. Because it is tied to specific Lenovo platform support, this power supply is positioned for administrators who need predictable fit, electrical compatibility, and a clean service experience. It is the kind of component that protects the value of the system already in place rather than forcing a broader hardware refresh.
