  • 250 W ATX power supply for 1U systems

Compact 250 W ATX unit

This KHACHIMO ZKS-250WX delivers 250 W of ATX power in a form factor built for ZECK 1U chassis. It targets system integrators and IT managers who need reliable, efficient power for dense rack or edge deployments where space and thermal budget are tight.

Gold efficiency and Modern Standby limits

The 80 PLUS Gold rating guarantees at least 80 % efficiency at typical loads, reducing waste heat and fan noise. Modern Standby support enables rapid wake-from-sleep, yet the platform must provide compatible firmware and a low-power CPU to benefit; older boards without the required sleep-state implementation will not see the faster resume times.

Headroom for single-socket servers

The 250 W ceiling comfortably runs a single low-TDP processor, a modest GPU or accelerator, and a handful of drives. Multi-GPU arrays, high-core-count CPUs, or large storage backplanes will exceed the available power, so builders planning such configurations must select a higher-wattage unit.

Questions about this item

Is the 250 W rating enough for a compact 1U build?

Yes, the 250 W output is sized for low-power 1U systems and the unit carries an 80 PLUS Gold rating for high efficiency.

What does the 80 PLUS Gold certification mean for daily use?

It guarantees high efficiency at typical loads, which lowers electricity draw, reduces heat output and keeps fan noise lower.

Does the ATX form factor fit a standard 1U chassis?

The supply uses an ATX design with -5 V and -12 V rails tailored for 1U rack-mount installations.
