KHACHIMO PWR-H5-ATX DC-ATX Power Supply

This DC-ATX unit accepts a 6 V to 34 V input and delivers 350 W of ATX power for compact systems. It is built for builders using Pico-style enclosures or industrial boards that run from a wide-range DC source. The Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency.

Thermals Noise and Power Draw

The 80 PLUS Gold certification guarantees high efficiency operation for lower power consumption, less noise and cooler temperatures. A Zero RPM fan mode stops the cooling fan entirely 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 for quieter performance.

Build Quality and Connectors

Resonant LLC topology with DC-to-DC conversion enables use of more energy efficient sleep states while maintaining stable output. The wide 6 V to 34 V input range suits diverse DC power environments without extra adapters. ATX output connectors fit standard motherboards, making integration straightforward for small form factor or embedded builds.

Questions about this item

How do I install the DC-ATX unit and which wiring step is most often missed?

Connect the 6-34 V DC input to the barrel or screw terminal, then plug the 24-pin ATX and CPU power cables into the motherboard; the step most often missed is securing the DC-input polarity before first power-on.

What maintenance will the 350 W supply need over its lifetime?

The 80 PLUS Gold unit has a Zero RPM fan mode, so dust the heatsink fins once a year and verify the fan spins freely when load exceeds the silent threshold.

Which limit appears first during sustained full-load operation?

The 34 V maximum input voltage is the first hard ceiling; exceeding it triggers protection shutdown before thermal or current limits are reached.
