Compact 1U PSU for space-constrained builds

This KHACHIMO Flex ATX unit delivers 270 W from an 80 Plus Gold platform built on an FSP270-60LE design. It targets small-form-factor chassis and 1U rack cases where a standard PSU cannot fit. The Modern Standby support keeps wake times short for always-connected workflows.

Gold efficiency caps peak output at 270 W

The 80 Plus Gold rating guarantees high efficiency at typical loads, yet the hard limit remains 270 W total. Systems drawing more than this under sustained load will trip protection or shut down. The smaller FSP220-60LE variant tops out at 220 W, so headroom is tight for discrete GPUs.

Flex ATX layout eases tight installs

The 1U height and short depth let the unit slide into narrow enclosures without cable routing conflicts. Zero RPM mode stops the fan at low load, but the compact heatsink can saturate quickly under continuous draw, causing the fan to spin up audibly. Verify your case airflow path before fitting.

Questions about this item

Which wattage version should I choose, the 220 W or the 270 W model?

The 270 W unit provides more headroom for power-hungry components, while the 220 W model suits lower-demand builds; both share the same 80 PLUS Gold efficiency and Modern Standby support.

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

It certifies high efficiency across typical loads, reducing wasted energy, heat output and fan noise compared with lower-rated supplies.

How does the ATX form factor limit installation in a small chassis?

The supply follows the ATX electrical standard but uses a compact 1U Flex size, so it fits slim ITX cases while delivering standard ATX power connections.
