Compact 1U ATX Power Supply

The KHACHIMO FLXE-ATX K39 is a 500W unit built to the 1U form factor for rackmount or slimline chassis. It targets system integrators and enthusiasts assembling space-constrained servers, workstations or HTPCs that still require standard ATX connectivity.

Sustained Load Behaviour

80 PLUS Gold certification confirms high efficiency across typical operating ranges, reducing waste heat during continuous operation. Resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation under prolonged load while suppressing coil whine. Zero RPM fan mode keeps the unit silent at low and medium loads, spinning up only when thermal demand requires active cooling.

Installation Notes

The 1U height fits approved slim enclosures, but cable routing in tight bays can be awkward due to the fixed cable bundle. Builders should verify chassis depth and connector clearance before purchase, as the compact housing leaves little room for excess cable management. Modern Standby support enables rapid wake-from-sleep, yet requires a compatible motherboard and operating system to function correctly.

Perguntas sobre este artigo

How loud is the fan during all-day use?

At low and medium loads the Zero RPM Fan Mode stops the fan completely for near-silent operation.

What cables must I already have to install this unit?

Standard ATX motherboard and peripheral cables are required; the supply uses a regular ATX pin-out.

Will it work reliably with older components I keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power suitable for legacy hardware.
