SKU CH-AJ7F-S7ABX

An ATX power supply delivering 14.5 V at 2.1 A and 3.6 A with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and LLC resonant topology for quiet, stable power

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep times
  • 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 operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • ATX form factor fits standard desktop cases for straightforward installation

ATX Power Supply with Modern Standby

The KHACHIMO ATX unit delivers 14.5V at 2.1A and 3.6A rails with 80 PLUS Gold certified efficiency. It is built for systems that require fast wake-from-sleep transitions and low-load energy savings. The resonant LLC topology with DC-to-DC conversion supplies clean power while reducing coil whine. This new component suits builders who prioritise quiet, efficient operation in compatible desktop chassis.

Suitable for Modern Standby PCs.

This supply fits computers that support Modern Standby sleep states and benefit from zero-RPM fan silence at typical loads. It is not intended for configurations demanding higher total output or multiple high-current rails beyond the rated 2.1A and 3.6A limits. Buyers needing greater headroom for multi-GPU arrays or extreme overclocking should look at higher-capacity units. The gold-rated efficiency helps keep thermals low in standard productivity or home-office machines.

Standard ATX installation with fan-curve awareness

Mounting follows the usual ATX screw pattern and connector layout, so most builders can swap it in without special tools. The zero-RPM mode engages automatically at low and medium loads, meaning the fan may stay still during idle or light work — this is normal, not a fault. Ensure case airflow can handle passive cooling when the fan is off. Coil whine is minimised by the LLC design, but sensitive ears in silent rooms may still detect faint noise at certain load points.

Questions about this item

What motherboard power connectors does the ATX unit provide for a modern system?

The supply uses a standard ATX form factor with 24-pin main, 8-pin EPS and PCIe cables to power current motherboards and graphics cards.

Will the 80 PLUS Gold efficiency and Zero RPM fan mode still benefit an older platform that lacks Modern Standby support?

Yes, the Gold-rated efficiency and silent fan operation at low loads work independently of the motherboard sleep implementation.

How can I confirm the 14.5 V rail is delivering stable voltage after installation?

Check the 14.5 V reading in BIOS or a hardware monitor; it should stay close to 14.5 V under load with minimal ripple.
