  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat

  • Resonant LLC and DC-to-DC design delivers clean power
  • 12-pin 250 W ATX unit fits FSP250-40TABAA builds

Purpose-Built Replacement

This 250 W ATX power supply is a direct replacement for the FSP250-40TABAA unit. It delivers 12 V output through a 12-pin connector for compatible small-form-factor or proprietary systems. The 80 PLUS Gold certification ensures high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Who It Suits

Builders restoring or servicing hardware that requires the exact FSP250-40TABAA pinout and 250 W rating will find this unit fits without adapters. The Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion suit noise-sensitive environments. Buyers who need higher wattage, a standard 24-pin ATX connector, or modular cables should look at other products.

Deciding Specification

The 12-pin connector and 250 W rating are the single specification that decides compatibility. This unit only powers systems designed for that exact connector and power level. Verify the original part number and connector keying before purchase.

Questions about this item

Does the KHACHIMO 12Pin 250W unit ship with all necessary cables or must any be purchased separately?

The power supply ships as a standalone unit; cable inclusion is not detailed in the specification, so verify the exact bundle with the seller before ordering.

How do I decide between the listed 12Pin 250W model and other capacities for my build?

Choose this 250W model only if your system power draw stays comfortably below that limit; higher-wattage units exist for more demanding hardware.

What does the 80 PLUS Gold rating mean for daily power draw and heat inside my case?

Gold certification means the supply runs at high efficiency across typical loads, reducing wasted electricity, lowering internal temperatures and allowing quieter fan behaviour.
