KHACHIMO 12v 24v 350W ATX Power Supply 80 PLUS Gold

350 W ATX power supply for compact builds

This KHACHIMO ATX unit delivers 350 W of 80 PLUS Gold certified power with 12 V and 24 V output options. It targets small-form-factor PCs, office workstations and modern-standby systems that prioritise efficiency and quiet operation over high-wattage headroom. The resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight for stable sleep-state transitions.

Standard ATX fit with semi-passive cooling

Installation follows the usual ATX mounting pattern and cable layout, so most builders can swap it in without case modifications. The Zero RPM fan mode stops the fan completely at low and medium loads, but the fan curve can spin up noticeably under sustained heavy draw, and coil whine may appear in very quiet rooms despite the LLC design. Ensure the 24-pin and CPU power cables reach your motherboard headers in tighter chassis.

Check 12 V or 24 V variant and total system draw

Verify whether your build requires the 12 V or 24 V model before ordering, as the two versions are not interchangeable. Add up the peak power draw of CPU, GPU, drives and peripherals to confirm 350 W covers your configuration with a safety margin. This unit lacks native 12 VHPWR or PCIe 5.0 connectors, so high-end graphics cards needing those plugs are not supported.
