ATX Power Supply for Modern Standby Systems

The KHACHIMO MP2-75525 is an ATX power supply built for PCs that use Modern Standby. It delivers 300 W of continuous power with 80 PLUS Gold certified efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails for reliable component operation.

Sustained Load Behaviour and Efficiency

Under continuous load the unit maintains its Gold-rated efficiency, reducing wasted energy and keeping internal temperatures lower. The DC-to-DC design ensures consistent voltage regulation across the rails during extended sessions. Modern Standby compatibility allows the system to enter and exit low-power states quickly without instability.

Thermals, Noise and Power Draw

A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. When the fan does spin, the efficient topology and Gold certification help minimise heat output and acoustic noise. The combination of resonant LLC conversion and DC-to-DC stages also reduces coil whine during normal use.

Questions about this item

How does the Zero RPM fan mode affect heat and noise when the 300V15A runs continuously?

At low and medium loads the fan stops completely, giving near-silent operation and cooler temperatures thanks to 80 PLUS Gold efficiency.

What motherboard and case fittings are required for this ATX unit to function?

It fits a standard ATX chassis and connects to a 24-pin main power socket plus an 8-pin CPU power header on the motherboard.

Will the resonant LLC topology with DC-to-DC conversion cause issues with older components I keep?

The topology delivers clean, consistent power and reduces coil whine, so it works reliably alongside legacy hardware.
