SKU CH-HKN1-NCVKN

An 80 PLUS Gold ATX power supply delivering 170 W with zero-RPM fan mode and resonant LLC topology for silent, efficient operation

  • TypeATX
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Modern Standby compatibility gives near-instant wake from sleep
  • Resonant LLC with DC-to-DC conversion delivers clean, stable power and reduces coil whine
  • ATX 170 W design fits standard builds with reliable output

What this 170W unit powers

This ATX power supply delivers 170 watts of continuous power with 80 PLUS Gold efficiency, making it suitable for compact desktops, thin-client upgrades or low-draw embedded systems. It targets builders who need reliable DC output in a small form factor without the bulk of higher-wattage units.

Efficiency and load limits

The Gold rating guarantees at least 80 percent efficiency at typical loads, reducing waste heat and electricity cost, but the 170 watt ceiling restricts use to processors and graphics cards with modest power envelopes. Modern Standby support enables rapid wake times, yet sustained heavy loads will push the fan into audible operation and may exceed the unit’s thermal headroom.

Installation notes

Standard ATX mounting holes and a conventional 24-pin connector simplify drop-in replacement in compatible chassis, though cable length is optimised for smaller cases and may fall short in full-tower layouts. The Zero RPM mode eliminates noise at idle, but coil whine can still appear under light loads if the motherboard’s power sequencing is aggressive, and the fixed cable set offers no modularity for tidy routing.
