Small-form-factor ATX supply for compact builds

The KHACHIMO Engine ITX SFX A50 A60 CSN500M is an ATX power supply designed for small-form-factor systems that require the SFX footprint. It targets builders assembling Mini-ITX or space-constrained rigs who need reliable, efficient power delivery without the bulk of a standard ATX unit.

500 W continuous output

Rated at 500 W, the unit comfortably handles mid-range CPUs and single-GPU configurations typical of compact gaming or workstation builds. The 80 PLUS Gold certification ensures high efficiency across the load range, reducing waste heat and keeping fan speeds lower, while the resonant LLC topology with DC-to-DC conversion provides clean, stable rails even as the system approaches its power limit.

Zero RPM fan mode and Modern Standby support

A Zero RPM fan mode stops the fan completely at low and medium loads, delivering near-silent operation during desktop work or media playback. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency, while the SFX form factor with standard ATX electrical specification allows straightforward mounting in compatible cases using the included bracket.

Questions about this item

Will the KHACHIMO CSN500M fit and power my existing ITX case that uses an SFX A50 or A60 bracket?

This SFX form factor unit is designed for ITX builds using A50 or A60 mounting brackets and delivers 500 W through a standard ATX connector set.

How can I confirm the Zero RPM fan mode is actually engaging after I install the CSN500M?

Under low and medium loads the cooling fan stops completely; you will hear near-silent operation and can verify the 80 PLUS Gold efficiency rating is active.

What cables come attached to the KHACHIMO Engine ITX SFX CSN500M and what must I source separately?

The power supply includes fixed ATX, CPU and PCIe connectors; any additional cables required for your specific build are not included.
