KHACHIMO 3.3V 15W ATX Power Supply

The KHACHIMO ECL15US03-S is a 15W ATX power supply delivering 3.3V at 3A. It targets ultra-low-power system builds, embedded applications or legacy hardware maintenance where minimal wattage and modern standby support are required.

Modern Standby Upgrade

This unit replaces older ATX supplies that lack Modern Standby compatibility and efficient low-load operation. The jump is worthwhile when building or servicing systems that demand fast wake-from-sleep times and 80 PLUS Gold efficiency at very light loads.

15W Capacity and Headroom

The 15W output comfortably handles ultra-low-power platforms, thin clients or legacy boards with modest 3.3V rail demands. It runs out when the system requires higher total wattage, additional voltage rails or sustained loads beyond the 3A limit on the single 3.3V output.

Perguntas sobre este artigo

Does this 3.3 V 3 A unit follow the ATX form factor for standard case mounting?

Yes, the specifications list the type as ATX, so it uses the standard mounting hole pattern and overall dimensions for ATX cases.

Which cable should be connected first when installing this supply to enable Modern Standby wake-from-sleep?

Connect the 24-pin ATX main power cable and the 4-pin or 8-pin CPU power cable before turning on the PSU switch; the motherboard then handles Modern Standby signalling.

Is the fan replaceable when the Zero RPM mode eventually wears out the bearing?

The fan is not designed for user replacement; if bearing noise appears after long use the entire power supply would need to be swapped.
