1U 250W Flex ATX Power Supply

This 1U Flex ATX unit delivers 250 W of continuous power for compact desktops, POS terminals and thin-client builds. It fits the small form-factor chassis that standard ATX supplies cannot enter, making it the choice for space-constrained commercial deployments. The new condition guarantees full manufacturer specifications from first power-on.

Sustained-load behaviour and efficiency

80 PLUS Gold certification means the supply maintains high efficiency across typical operating loads, reducing waste heat and keeping internal temperatures lower during long shifts. Resonant LLC topology with DC-to-DC conversion provides clean, consistent output rails that stay stable when the system runs continuously. Zero RPM fan mode keeps the unit silent at low and medium loads, spinning up only when thermal demand requires active cooling.

Modern Standby compatibility

Modern Standby support enables extremely fast wake-from-sleep transitions and improved low-load efficiency for always-connected workflows. Systems that rely on instant resume and deep sleep states will benefit from this capability. Builds that do not use Modern Standby or that require higher wattage for discrete graphics should consider other form-factor options.

Questions about this item

How loud and hot does the 250W unit run when it powers a system all day?

The 80 PLUS Gold certified 250W supply uses Zero RPM fan mode, so the fan stays off at low and medium loads for near-silent operation and cooler temperatures.

Which cables or connectors must I already have to install this DPS-250AB-24C or DPS-250AB-44A unit?

This is an ATX type power supply; it requires standard ATX motherboard and peripheral connectors already present in the chassis.

Will the resonant LLC topology with DC-to-DC conversion cause issues with older components I keep in the build?

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine, making it compatible with legacy hardware.
