  • TypeATX
  • Modern Standby compatibility for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency, lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the cooling 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 with 12V 33A output for reliable system power delivery

12 V 33 A ATX unit

The KHACHIMO Q48SH12033NN H delivers a 12 V rail rated at 33 A for standard ATX systems. It suits builders assembling office or home PCs that require reliable power without excess capacity.

Modern Standby and Gold efficiency

This supply replaces older units that lack Modern Standby support and lower efficiency ratings. The jump is worthwhile when faster wake-from-sleep and reduced idle draw matter for daily use.

Zero RPM mode under sustained load

At low and medium loads the fan stops completely, keeping noise to a minimum. Resonant LLC topology with DC-to-DC conversion maintains clean output and limits coil whine during extended operation.

Questions sur cet article

What form factor does the Q48SH12033NN H use for ATX mounting?

The unit follows the standard ATX form factor, so it fits any chassis with a regular ATX power-supply cut-out and four rear mounting screws.

Which cables must be connected first during installation to enable Modern Standby?

Attach the 24-pin ATX and 12 V CPU connectors before any peripheral cables; skipping the CPU 12 V link is the most common reason Modern Standby fails to initialise.

When should the fan bearing be inspected on a unit running Zero RPM mode?

Because the fan stays off at low and medium loads, check the bearing for dust or noise after roughly two years of continuous use, then clean or replace if needed.
