KHACHIMO DPS-750AB-31A 750W ATX power supply

SKU CH-ZYEM-E9066

An 80 PLUS Gold ATX power supply with Zero RPM fan mode and Modern Standby compatibility for quiet, efficient operation

  • Product typeATX
  • Faster wake from sleep with Modern Standby support
  • Lower energy draw thanks to 80 PLUS Gold efficiency
  • Silent running at low loads via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC with DC-to-DC
  • Cooler, quieter operation from high-efficiency Gold-certified design

Ready for Modern Standby systems

This 750 W ATX unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. It targets builders who want a new, efficient power supply for contemporary desktop platforms. Buyers needing redundant or server-grade hot-swap modules should look elsewhere.

Quiet operation through Gold efficiency

The 80 PLUS Gold rating reduces waste heat, helping the unit run cooler and quieter under typical loads. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports efficient sleep states.

750 W ATX form factor

This supply delivers 750 watts in a standard ATX package, matching the single capacity and form-factor spec that determines fit and power budget. No other wattage or physical variant is described in the data. Builds requiring a different output or a non-ATX chassis layout will need another unit.

Questions about this item

How do I install this 750W ATX power supply and what step is often missed?

Mount the unit in the case with four screws, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will this DPS-750AB-31A need over time?

The Zero RPM fan mode keeps the fan off at low loads, so dust builds up more slowly; clean the intake grill with compressed air once a year and the fan bearings should last the unit's lifetime.

What limit appears first when this supply runs at sustained load?

The 80 PLUS Gold rating means efficiency stays high, so the first limit is usually the internal temperature threshold that spins the fan up from zero RPM to active cooling.
