Compact ATX PSU for Small Form Factor Builds

The Khachimo B325I is a 250W ATX power supply designed for compact desktop systems. It carries 80 PLUS Gold certification for high efficiency and lower running temperatures. Modern Standby compatibility enables extremely fast wake-from-sleep times. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suited for Low-Power Systems.

This unit suits builds with modest power requirements such as office PCs, home servers or thin-client replacements. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. Buyers planning to run discrete graphics cards or high-wattage CPUs should look at higher-capacity power supplies instead.

250W Continuous Output Decides Fit

The single specification that determines compatibility is the 250W continuous power rating. Verify that the total system draw under full load stays within this limit before purchasing. The unit includes an 8-pin connector among its cable complement for motherboard power.

Questions about this item

What physical size and power connectors does the KHACHIMO B325I 250W ATX supply need for mounting?

The unit follows the standard ATX form factor and includes an 8-pin connector for the motherboard, fitting typical ATX cases and boards.

How do I install the B325I and what step is often missed?

Secure the PSU with four screws in the case, plug the 24-pin ATX and 8-pin CPU cables firmly, then enable Modern Standby in the BIOS so the fast wake and low-load efficiency features actually work.

What maintenance will the B325I need over its life?

The Zero RPM fan stops at low and medium loads, so dust builds up more slowly; simply blow compressed air through the grille once a year to keep airflow clear.
