KHACHIMO GW-2UR550 550W 80 PLUS Gold Power Supply

KHACHIMO 550W Gold ATX PSU

The KHACHIMO GW-2UR550 is a 550W ATX power supply certified 80 PLUS Gold for high efficiency. It uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suits builds needing Gold efficiency

This unit fits systems that benefit from high efficiency, lower power draw and reduced noise at idle. The Modern Standby support suits PCs using low-power sleep states. Builds requiring higher wattage than 550W or non-ATX form factors should look at alternative units. The specific server model compatibilities listed may not apply to standard desktop cases.

Standard ATX installation

Installation follows standard ATX mounting and cabling procedures in compatible chassis. The zero RPM fan mode activates automatically at low and medium loads, so the fan may remain off during light use. Coil whine is reduced by the resonant LLC and DC-to-DC design. Ensure the 550W capacity matches the total system power requirement before fitting.
