460W ATX Power Supply

The KHACHIMO 460W ATX power supply is designed as a direct replacement for compatible Lenovo ThinkServer and System x platforms including the X3250, X3550 and X3650 M2, M3 and M5 models. It delivers 460 watts of continuous power with 80 PLUS Gold certified efficiency and Modern Standby support for rapid wake-from-sleep performance.

Practical Limits of ATX Interface

The unit follows the standard ATX form factor and connects through the proprietary pinout used by the listed server chassis, so it will not fit a generic desktop motherboard without an adapter. Its 460W ceiling restricts use to configurations that stay within this power budget, and the Modern Standby feature only functions with platforms that implement the corresponding low-power idle states.

Capacity and Headroom

At 80 PLUS Gold efficiency the supply wastes less energy as heat, keeping fan speeds low and enabling the Zero RPM mode to silence the fan entirely at light loads. The 460W rating comfortably supports typical single-processor server builds with modest storage and expansion, but multi-GPU arrays or heavily loaded dual-CPU configurations will exceed its headroom.
