550W ATX Power Supply

The KHACHIMO U1A-D10550-DRB is a new ATX switching power supply rated at 550W. It carries 80 PLUS Gold certification for high efficiency and uses resonant LLC topology with DC-to-DC conversion for clean power delivery. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Silent Builders Seeking Efficient Sleep States

This unit suits builders who want a quiet, efficient PSU for modern sleep states. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. The resonant LLC design reduces coil whine. Buyers who need higher wattage for multi-GPU setups or extreme overclocking should look at higher-capacity units.

80 PLUS Gold Certified 550W Output

The 80 PLUS Gold rating guarantees high efficiency at typical loads, lowering power consumption, noise, and temperatures. Combined with the 550W capacity, this certification is the key indicator of whether the unit meets your build's power and efficiency requirements.
