ATX 200W Gold unit

The KHACHIMO GW-EP200WV5AA-00 is an ATX power supply rated at 200W with 80 PLUS Gold certification. It uses a resonant LLC topology with DC-to-DC conversion to deliver clean power and support modern sleep states. The unit suits compact builds or upgrades where modest output and high efficiency are priorities. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Compatibility checks

Verify that your motherboard uses standard ATX power connectors and that the total system draw stays within the 200W rating. Confirm the 5V rail can supply up to 40A for your connected devices. Ensure the chassis has space for a standard ATX form factor unit and that cable lengths reach all components. Buyers needing higher wattage or additional PCIe connectors should consider other options.

Sustained-load behaviour

At low and medium loads the Zero RPM fan mode stops the fan completely for near-silent operation. Gold-rated efficiency reduces waste heat, keeping temperatures lower during continuous use. The resonant LLC design maintains stable voltage regulation and reduces coil whine over long sessions. The power supply supports energy-efficient sleep states without sacrificing output quality.
