  • 80 PLUS Gold certified for lower consumption, less noise and cooler running

Compact 1U Flex ATX Power Supply

This KHACHIMO Flex ATX unit delivers 380 W continuous power with a 450 W peak rating in a 1U form factor. It targets builders assembling small-form-factor PCs, rack-mount appliances or upgrades for proprietary chassis that require the Flex ATX footprint.

Suits space-constrained builds needing Gold

The 80 PLUS Gold certification, Zero RPM fan mode and Modern Standby support make it a strong fit for quiet workstations, home servers or HTPCs that spend long periods at low load. Builds requiring more than 380 W sustained output or a standard ATX-sized enclosure should look elsewhere.

380 W continuous rating is the deciding spec

If the system’s peak draw stays below 380 W this supply will handle it; if the load regularly exceeds that figure the unit is undersized regardless of its 450 W peak capability.

Questions about this item

Which KHACHIMO flex ATX model should I choose, the K39 or the K35?

The K39 and K35 are the two model variants supplied under the HYC380-1U designation; both share the same 380 W continuous and 450 W peak ratings.

What does the 380 W continuous rating mean for my build?

It guarantees the unit can deliver 380 W of combined DC output continuously, with brief peaks to 450 W, while maintaining 80 PLUS Gold efficiency and Modern Standby fast wake.

What interface does this power supply use and what does it limit?

It uses the standard ATX power interface, limiting installation to chassis and motherboards that accept a 1U Flex ATX form factor.
