Compact 125W ATX unit for low-power builds

The KHACHIMO MPB125-2012G is a 125W ATX power supply built for small-form-factor systems, thin clients or embedded appliances that draw very little power. Its modest output makes it unsuitable for discrete graphics cards or multi-drive arrays, so builders planning high-performance desktops should look elsewhere.

Steady output with fanless low-load operation

Under sustained load the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and ripple low, while the 80 PLUS Gold rating ensures high efficiency across the load range. The Zero RPM fan mode stops the fan completely at low and medium loads, eliminating acoustic noise during typical idle or office workloads.

Modern Standby support and quiet construction

Modern Standby compatibility allows the supply to enter and exit ultra-low-power sleep states rapidly, reducing wake latency for always-connected devices. The combination of LLC resonance and DC-to-DC stages also suppresses coil whine, so the unit stays quiet even when the fan eventually spins up.

Questions about this item

How loud does the 125W unit get under full load all day?

The 80 PLUS Gold certification keeps heat low, so the fan only spins when needed and stays quiet at higher loads.

Which cables must my build already have for this ATX supply to work?

Your motherboard needs a standard 24-pin ATX connector and a 4-pin or 8-pin CPU power plug; the PSU includes matching cables.

Will the MPB125-2012G cause issues with an older motherboard that lacks Modern Standby?

No, the supply works with any ATX board; Modern Standby features simply remain inactive on legacy platforms.
