Ruth's sister TFX 250W Power Supply DY72N

SKU CH-4T1M-G0EDP

Compact TFX power supply delivers 250 W with 24-pin and 4-pin CPU connectors plus three SATA ports for desktop or server builds

  • Fits compact TFX cases with 250 W output
  • Powers legacy desktops and servers from 100-264 V input
  • Connects up to three SATA drives directly
  • Non-modular design keeps cabling simple for small builds
  • Includes 24-pin ATX and 4-pin CPU connectors

Slimline 250W TFX Power Supply

This TFX form-factor unit delivers 250 watts for compact desktop or server chassis. It fits systems that require the narrow TFX profile and a standard 24-pin motherboard connector. The non-modular design keeps cabling simple for small-case builds. Buyers needing higher wattage or modular cables should look elsewhere.

Four-Pin CPU Power Connector

The power supply provides a single 4-pin CPU power connector rather than an 8-pin EPS connector. This limits compatibility to motherboards that accept a 4-pin CPU power input. Systems requiring an 8-pin or dual 8-pin CPU power connection cannot use this unit.

Three SATA Power Connectors

Three SATA power connectors are included for drives and peripherals. No PCIe power connectors are present, so discrete graphics cards requiring external power are not supported. The bundled cables cover basic storage needs in a compact build.

Questions about this item

What does the 250 W rating mean once the PSU is installed in my machine?

It is the maximum continuous power the unit can deliver to all rails combined, so the total draw of CPU, drives and motherboard must stay below 250 W.

What does the 24-pin interface cap in practice?

The 24-pin ATX connector supplies the motherboard main power and is limited by the unit’s 250 W total output across all rails.

What does the TFX form factor need to fit in my case?

A TFX-compatible chassis with the matching mounting holes and enough depth for the standard TFX body length.
