KHACHIMO GX520 GX620 220W ATX power supply 80 PLUS Gold

KHACHIMO 220W ATX Power Supply

The KHACHIMO GX520 GX620 is a 220W ATX power supply built for small-form-factor desktops and office workstations. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times and improved low-load efficiency. The unit uses a resonant LLC topology with DC-to-DC conversion to deliver stable power and reduce coil whine. A zero RPM fan mode stops the fan completely at low and medium loads for silent operation.

Compatibility Check Before Ordering

Verify that your chassis accepts a standard ATX power supply and that 220W meets the combined draw of your CPU, GPU, drives and peripherals. Confirm the unit's fixed cable set provides the required motherboard, CPU and peripheral connectors for your build. Ensure the physical dimensions fit your case, as compact enclosures may restrict length or connector clearance. No modular cables are included, so cable routing space must accommodate the full loom.

Who This Suits and Who Should Look Elsewhere

This supply suits integrators and upgraders refreshing proprietary OEM systems such as the 5100C, 5150C, N220P-01, H220P-01, R8038, H220P-00 or N220P-00 models. It also fits low-power custom builds that value quiet operation and Gold-rated efficiency at modest loads. Builders needing more than 220W for discrete graphics cards, high-core-count CPUs or multiple drives should look elsewhere. Systems requiring modular cabling or higher peak power headroom are not a match.
