Ruth's sister internal power cable TF300W1 250W 1U FlexATX

SKU CH-R6GY-T57YQ

A 250 W FlexATX 1U supply with passive PFC, 72 % efficiency and 20-pin ATX connector for compact desktop or server builds

  • 250 W rated output powers compact desktop and POS builds
  • Passive PFC keeps design simple for 115 / 220 V switched input
  • 72 % efficiency reduces heat in 1U FlexATX chassis
  • Intel FlexATX 1.01 compliance ensures mechanical fit in ITX cases
  • Built-in over-voltage, short-circuit, under-voltage and overload protection safeguards components

250 W FlexATX 1U power supply

This 250 W FlexATX unit fits 1U and Mini-ITX chassis where a compact TF300W1 form factor is required. It delivers 250 W of continuous power through a fixed, non-modular cable set. The passive power-factor correction circuit operates on 184–264 V AC input. A 4 cm fan provides cooling for industrial or desktop deployments.

Suited for space-constrained builds.

The supply suits POS terminals, thin clients, Mini-ITX desktops and 1U servers that need a 20-pin main connector, a 4-pin CPU lead and two SATA power plugs. Builds requiring a 24-pin ATX connector, an 8-pin CPU connector, PCIe power cables or more than two SATA drives cannot use this unit. Active PFC or 80 PLUS Bronze efficiency seekers should look elsewhere.

250 W rated output at 72 % efficiency

The single deciding specification is the 250 W rated output combined with 72 % typical efficiency. This figure determines whether the unit can sustain the load of a given low-power platform without overheating or tripping its over-current protection.

Questions about this item

Should I pick the 250W FlexATX unit for a 1U POS chassis or a Mini-ITX build?

The 250W FlexATX form factor fits 1U industrial cases and Mini-ITX systems such as POS terminals, diskless workstations and thin clients.

What does the 250W rating deliver in a live system?

Rated output is 250W at 72% efficiency with a minimum 16ms hold-up time and a 100-500ms power-good signal.

How does the 20-pin main connector limit motherboard compatibility?

The 20-pin ATX connector plus a 4-pin CPU plug and two SATA power leads support legacy and entry-level boards that do not require a 24-pin socket.
