Compact 1U Flex ATX power supply for specialised

This 500 W ATX unit fits the 1U form factor and delivers a -12 V rail, making it suitable for small industrial chassis or legacy server boards that require the negative voltage line. It is intended for integrators who need a tested, good-quality replacement for proprietary OEM power modules.

Thermals noise and power behaviour in normal use

The supply operates within standard ATX tolerances and draws up to 500 W from the mains under full load. Cooling is handled by the internal 1U fan assembly; acoustic output will vary with load and chassis airflow. No additional thermal or noise specifications are provided.

Questions about this item

How do I install the DPS-500AB-5B into a 1U chassis and what step is often missed?

Slide the 1U unit into the chassis, secure it with the four mounting screws, then connect the 24-pin ATX main cable and the 4-pin 12V CPU cable; the step often missed is plugging in the -12V auxiliary lead required by some ITX boards.

What maintenance will the DPS-500AB-5B need later?

Clean dust from the intake vents and internal fan every 6 to 12 months; the unit has no user-serviceable parts, so if output voltages drift or the supply shuts down under load, replace the entire power supply.
