KHACHIMO

KHACHIMO 27V50A 80 PLUS Gold ATX power supply

SKU CH-BBB0-S1QVT

ATX power supply delivering 27V 50A with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Fast wake-from-sleep and better low-load efficiency with Modern Standby support
  • High-efficiency operation lowering power draw, noise and heat via 80 PLUS Gold certification
  • Near-silent running at low and medium loads thanks to Zero RPM fan mode
  • Clean, consistent power delivery and reduced coil whine from resonant LLC topology with DC-to-DC conversion
  • Energy-efficient sleep states enabled by resonant LLC topology with DC-to-DC conversion

Modern Standby ATX Supply

The KHACHIMO 27V50A is an ATX power supply built for systems that use Modern Standby sleep states. Its 80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and lowering overall power draw. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent voltage rails for stable component operation.

Sustained Load Behaviour

Under continuous demand the unit maintains tight voltage regulation thanks to its resonant LLC design and DC-to-DC conversion stages. This topology minimises ripple and suppresses coil whine even when the supply runs for extended periods. The Zero RPM fan mode stays inactive once the load exceeds its threshold, so active cooling engages only when thermally necessary.

ATX Interface Practical Limits

As an ATX form-factor unit it fits standard chassis cut-outs and connects to mainstream motherboards through the usual 24-pin, CPU and peripheral cables. The Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency supported by the platform. Builders needing higher total wattage or specialised server-grade redundancy should evaluate alternatives.

Questions about this item

How loud and hot does the KHACHIMO 27V50A get when running 24/7?

The 80 PLUS Gold certification keeps power draw, heat and noise lower. At light and medium loads the Zero RPM Fan Mode stops the fan completely for near-silent operation, while the resonant LLC topology with DC-to-DC conversion reduces coil whine.

What cables or connectors must I already have to install the KHACHIMO 27V50A?

The unit uses a standard ATX form factor, so it fits any ATX-compatible case and connects to a motherboard with the usual 24-pin ATX, CPU and peripheral power cables that come with the power supply.

Will the KHACHIMO 27V50A work properly with an older motherboard that does not support Modern Standby?

Yes. Modern Standby compatibility only enables faster wake times and better low-load efficiency on supported platforms; on older boards the supply still delivers clean, stable power through its resonant LLC and DC-to-DC design.
