SKU CH-KZQQ-ZKDEN

A compact 1U ATX power supply delivering 220W to 300W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for quiet, efficient operation

  • TypeATX
  • Fast wake and efficient sleep with Modern Standby support
  • 80 PLUS Gold certification cuts power draw and heat
  • Fan stops completely at low loads for silent running
  • Resonant LLC with DC-to-DC delivers clean power and reduces coil whine
  • Compact 1U form factor fits space-constrained server chassis

1U ATX power supply for compact builds

This 1U form-factor ATX unit delivers 220 W continuous and 300 W peak power for space-constrained chassis. It targets system integrators and enthusiasts building low-profile servers, workstations or HTPCs where height is the limiting factor.

80 PLUS Gold thermals and Zero RPM fan

Certified 80 PLUS Gold efficiency reduces waste heat and keeps internal temperatures lower during typical workloads. The Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern sleep states.

Modern Standby support and LLC topology

Modern Standby compatibility enables extremely fast wake-from-sleep and improved low-load efficiency for always-on deployments. The resonant LLC design with DC-to-DC conversion provides clean, consistent power delivery and quieter operation without requiring oversized cooling.

Preguntas sobre este artículo

How do I install this 1U ATX power supply in a rackmount chassis, and which step do builders most often miss?

Slide the unit into the 1U bay, secure the four mounting screws, then connect the 24-pin ATX, CPU and peripheral cables; the step most often missed is plugging in the 4-pin or 8-pin CPU power connector near the socket.

What maintenance will this 80 PLUS Gold unit need over its service life?

The Zero RPM fan mode keeps the fan off at low and medium loads, so dust intake is minimal; plan to blow out the heatsink fins once a year and listen for bearing noise — if the fan becomes audible under load, replace the fan assembly.

What is the first limit reached when this 220 W continuous / 300 W peak supply runs at sustained high load?

The 220 W continuous rating is the first ceiling; exceeding it triggers over-power protection and shuts the unit down, while the 300 W peak is only available for short bursts.
