KHACHIMO power supply 3.3 V 70 A ATX 80 PLUS Gold

SKU CH-A59N-MT232

An ATX power supply delivering 3.3 V at 70 A with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for silent, efficient Modern Standby operation

  • TypeATX
  • Modern Standby compatibility enables extremely fast wake-from-sleep times
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 3 V 70 A output supplies stable power for demanding components

3.3 V 70 A ATX power supply

This KHACHIMO unit delivers a 3.3 V rail rated at 70 A in a standard ATX form factor. It is built for systems that require strong minor-rail current and modern sleep-state support. The 80 PLUS Gold certification confirms high efficiency across typical load ranges. It suits builders who want quiet, efficient power for compatible platforms.

70 A on the 3.3 V rail

The single specification that decides fit is the 3.3 V output rated at 70 A. Boards or backplanes that draw heavy minor-rail current need this capacity to remain stable. If the target hardware demands less current on this rail, a lower-rated unit would suffice. Verify the exact 3.3 V requirement before purchasing.

ATX layout with Modern Standby support

The supply uses an ATX footprint and includes Resonant LLC topology with DC-to-DC conversion for clean power delivery. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. It frees the builder from fan noise during idle workloads.

Questions about this item

What does the 3.3 V 70 A rating mean for my build?

The 3.3 V rail can deliver up to 70 A, supplying ample current for logic components and low-voltage peripherals in a modern system.

How does the ATX form factor and 80 PLUS Gold rating affect daily use?

ATX ensures the unit fits standard chassis cut-outs and mounting holes, while Gold certification guarantees high efficiency across typical loads, reducing heat and fan noise.

What clearance and mounting points does this power supply need?

It uses the standard ATX footprint with four rear mounting screws and requires enough depth in the case for the unit length and cable bend radius.
