KHACHIMO MKP680 ATX Power Supply 24V 17A 80 PLUS Gold

24 V ATX power supply for modern standby systems

This ATX power supply delivers a 24 V rail rated at 17 A alongside 4.5 A on a secondary 24 V output, 10 A at 5 V, 0.5 A at 15 V and 0.1 A at -15 V. It targets builders who need an ATX form-factor unit that supports Modern Standby sleep states for rapid wake times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion supplies clean power while reducing coil whine.

Efficiency limits of 80 PLUS Gold at low load

The 80 PLUS Gold certification guarantees high efficiency at typical loads, but the standard does not define efficiency requirements below 10 % of rated output. Systems that spend long periods in deep sleep or idle may therefore draw more wall power than the Gold badge alone suggests. Zero RPM fan mode eliminates fan noise at low and medium loads, yet the fan must spin up once thermal thresholds are crossed, introducing audible noise under sustained heavy demand.

17 A on the primary 24 V rail decides suitability

The single specification that determines fit is the 17 A maximum current on the main 24 V rail, which sets the peak power available for 24 V-dependent components. If the build requires more than 17 A at 24 V this unit cannot meet the demand, while systems needing only modest 24 V current will operate within its design envelope. The auxiliary rails at 5 V, 15 V and -15 V provide fixed supplementary current for legacy or low-power circuits.
