Ruth's sister internal power cable 250W FLEX ITX-1U

SKU CH-79MZ-PFYG6

A 250 W Flex ATX 1U power supply with passive PFC, 72 % efficiency, two SATA connectors and a 4-pin CPU plug for compact servers or desktops

  • Fits compact ITX-1U builds with FlexATX 1.01 compliance
  • 250W continuous output powers low-power servers and NAS units
  • 72% efficiency reduces heat in small enclosures
  • Passive PFC with 115/220V switch suits global mains
  • Two SATA and two D-type connectors drive storage and peripherals

Purpose & Fit

This 250W FLEX ITX-1U power supply serves compact desktops, cash registers, NAS units and low-power industrial systems. It targets builders who need a 1U form-factor unit compliant with the Intel FlexATX 1.01 specification for space-constrained chassis.

Compatibility Check

Verify that your chassis accepts a 1U FLEX ATX outline and that the motherboard uses a 20-pin main power connector plus a 4-pin CPU power plug. The unit provides two SATA power connectors and two D-type peripheral plugs; it has no 12 V graphics-card pins, so discrete GPU builds are not supported.

Thermals, Noise & Power

A 4 cm fan cools the non-modular unit while it delivers up to 250 W continuous output at 72 % typical efficiency. Protective circuits cover over-voltage, under-voltage, short-circuit and overload events. The power-good signal settles within 100-500 ms and hold-up time is rated at 16 ms minimum. Input range covers 184-264 V AC with a manual 115/220 V selector switch.
