SKU CH-HWPK-5Q9R5

Delivers 750 W at 27 V and 27.8 A with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC DC-to-DC topology for silent, stable power

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption and cooler operation
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 750 W output at 27 V and 27.8 A supplies ample power for demanding ATX builds

Modern Standby ATX Power Supply

The KHACHIMO RSP-750-27 is an ATX power supply built for systems that require a 27 V rail. It suits desktop builds needing Modern Standby compatibility for rapid wake-from-sleep transitions. The 80 PLUS Gold certification confirms high efficiency across typical load ranges.

750 W Output with 27.8 A Capacity

This unit delivers a continuous 750 W with the 27 V rail rated for 27.8 A, providing ample headroom for demanding components on that voltage. The resonant LLC topology with DC-to-DC conversion maintains stable regulation and clean power delivery. Loads exceeding the rated output will trigger protection and cannot be sustained.

Zero RPM Fan Mode and Gold Efficiency

At low and medium loads the cooling fan stops completely, enabling near-silent operation during everyday tasks. The 80 PLUS Gold rating reduces waste heat, keeping internal temperatures lower and contributing to quieter performance. Coil whine is minimised by the LLC resonant design.

Questions about this item

Will the 750W 27V 27.8A ATX unit fit and power my existing ATX chassis and motherboard without adapters?

Yes, the power supply uses the standard ATX form factor and connects to a 24-pin motherboard header plus CPU and PCIe cables, so it slots straight into any ATX case and board you already own.

How can I confirm the 80 PLUS Gold efficiency and Modern Standby support are active after installation?

Windows will report Modern Standby in the powercfg /a output, and the fan will stay off at idle thanks to Zero RPM mode, confirming the Gold-rated platform is operating as designed.

Which cables come in the box with the RSP-750-27 and what must I source separately?

The box contains the PSU, an AC power cord and the fixed ATX, CPU and PCIe cables; any additional PCIe or peripheral leads for extra GPUs or drives must be purchased separately.
