50 W ATX Power Supply

The KHACHIMO PMT unit delivers 12 V at 4.2 A for a total of 50 W, making it suitable for low-power industrial PCs, thin clients or embedded systems that require an ATX form factor. Its 80 PLUS Gold rating ensures high efficiency across the load range.

Standard ATX mounting and connectors

Installation follows the usual ATX screw pattern and main power connector, so it fits existing chassis cut-outs without modification. The resonant LLC topology with DC-to-DC conversion reduces coil whine, though builders should verify that the 50 W ceiling covers every rail their board draws.

50 W output ceiling

The 50 W limit restricts use to platforms with very modest CPU and peripheral demands; discrete graphics cards or multi-drive arrays will exceed the available power. Zero RPM fan mode keeps acoustics low at light loads, but sustained heavy draw will activate cooling and still cannot raise the wattage ceiling.

Perguntas sobre este artigo

How can I confirm the 12V rail is delivering 4.2A after installation?

Use a multimeter on the 12V rail while the system is under load; a steady reading near 12V at up to 4.2A shows the 50W unit is working as intended.

Which cables and connectors come in the box with this ATX power supply?

The box includes the ATX power supply unit with its fixed cables; no modular cables or extra adapters are supplied.

Should I choose the 12V 4.2A 50W version or a higher-wattage model for my build?

Select this 12V 4.2A 50W unit only if your total system draw stays below 50W; otherwise choose a higher-wattage ATX supply.
