Compact 1U ATX Power Supply

The KHACHIMO IPC Small 1U DPS-350AB-24 B delivers 350W of continuous power in a slim 1U form factor designed for space-constrained chassis. It targets system integrators and builders assembling compact workstations or servers where standard ATX units will not fit.

Thermals Noise and Power Draw

80 PLUS Gold certification ensures high efficiency during normal operation, reducing waste heat and overall power consumption. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running, while Resonant LLC topology with DC-to-DC conversion minimises coil whine and maintains stable voltages.

Modern Standby and Topology Benefits

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for always-on responsiveness. The Resonant LLC design with DC-to-DC conversion further supports efficient sleep states and cleaner power delivery for sensitive components.

  • Lower power draw and cooler running with 80 PLUS Gold efficiency
  • Near-silent operation at low loads via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC and DC-to-DC topology

Questions about this item

How do I install this 1U DPS-350AB-24 B unit in a rack chassis, and which step is often missed?

Slide the 1U power supply into the rack bay, secure the mounting screws, connect the ATX cables to the motherboard and drives, then enable Modern Standby in the BIOS so the fast wake and low-load efficiency features actually work.

What maintenance will this 350W Gold supply need over time?

The Zero RPM fan stops at low and medium loads, so dust builds up more slowly; vacuum the intake mesh once a year and verify the fan spins freely when the load exceeds the silent threshold.

Which limit appears first when this 80 Plus Gold unit runs at sustained load?

The 350 watt continuous rating is the first ceiling; once total system draw reaches that level the protection circuits will shut the unit down to prevent overload.
