Product Identity

The KHACHIMO ST-250WHV is a 250W ATX power supply intended for legacy desktop systems that still use the AT form factor. It provides a tested, working unit for repair technicians or hobbyists maintaining older hardware.

Sustained Load Behaviour

The unit delivers a continuous 250W output suitable for basic office workloads and period-correct components. It is not designed for modern high-draw graphics cards or multi-drive arrays that exceed this capacity.

Installation Notes

The ATX designation indicates standard mounting holes and connector layouts for compatible vintage cases. Builders must verify that their motherboard requires AT-style power connectors rather than newer ATX variants.

Questions about this item

How much heat and noise does the 250W ATX unit produce when running continuously?

The 250W ATX power supply is tested working and built with good quality components, which helps keep heat output and fan noise at reasonable levels during all-day operation.

What motherboard power connector must my system already have for this ATX supply to work?

This unit uses the older AT style connector, so your motherboard must provide a matching AT power socket rather than the modern 24-pin ATX plug.

Will the 250W ATX supply reliably power legacy ISA or early PCI cards I want to keep using?

Rated at 250W with an AT connector, it delivers the voltage rails that older expansion cards expect, making it a direct fit for vintage builds.
