75 W ATX Gold power supply

The KHACHIMO PMT 75W ATX unit is a compact 80 PLUS Gold certified power supply designed for low-power desktop builds and modern standby systems. It delivers 75 watts of continuous power through a resonant LLC topology with DC-to-DC conversion for clean voltage regulation. The supply targets builders who need efficient, quiet operation in small form factor or office PCs. It is not suited for systems requiring higher wattage or multiple PCIe power connectors.

Sustained-load behaviour

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains stable output while keeping temperatures lower than less efficient designs. The 80 PLUS Gold rating ensures high efficiency across typical operating ranges, reducing waste heat and allowing the zero RPM fan mode to stay active longer. At low and medium loads the cooling fan switches off entirely for near-silent operation, while the topology also reduces coil whine for quieter performance overall.

Modern standby compatibility

Modern standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency, making this unit the right choice for PCs that frequently enter and exit low-power states. The feature supports energy-efficient sleep states demanded by contemporary operating systems and firmware. Builders whose systems do not use modern standby will not benefit from this specific capability.

Questions about this item

How loud and warm does the 75 W unit get when it runs continuously?

80 PLUS Gold efficiency keeps waste heat low, and the Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Which cables must my build already provide for this PSU to work?

The ATX form factor requires a standard 24-pin motherboard connector and a 4+4-pin CPU power connector from the supply itself; no proprietary adapters are needed.

Will the resonant LLC and DC-to-DC design cause issues with an older motherboard that lacks Modern Standby?

The topology simply delivers clean, stable power and reduces coil whine; it works with any ATX-compatible board regardless of sleep-state support.
