KHACHIMO YM-2451C 3Y Server Power Supply 450W

450 W ATX server power supply

The KHACHIMO YM-2451C delivers 450 W through a standard ATX form factor for rack or tower servers. It arrives new and has been tested as working by the supplier. The unit targets system integrators and IT teams who need a reliable replacement or spare for compatible server chassis. First listed by the manufacturer in 2024.

Suits 450 W ATX server builds; not for higher loads

This supply fits servers designed around a 450 W ATX power budget and the YM-2451C pinout. Builders who need more wattage, redundant modules or a different form factor such as CRPS should look at other units. The 3 Y designation suggests a three-year design life, so buyers planning longer deployments may prefer a model rated for extended service.

Simple ATX swap; verify pinout first

Installation follows the usual ATX power-supply replacement procedure: remove the old unit, seat the YM-2451C, and connect the main and peripheral cables. The most common issue is a pinout mismatch on proprietary server backplanes, so confirm the connector layout matches the chassis before powering on. No extra adapters are mentioned in the supplied data.
