33 V 100 W ATX power supply

This ATX unit delivers a fixed 33 V output at up to 3 A for 100 W total power. It is built as a direct replacement for ECM100US33 and ECM100US industrial modules. System integrators who need a compact, regulated 33 V source for embedded boards or legacy back-planes will find it fits the same footprint.

80 PLUS Gold certified efficiency

The supply meets 80 PLUS Gold requirements, so it wastes less energy and generates less heat across the load range. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine. Modern Standby support allows the system to enter and exit low-power sleep states quickly.

Zero RPM fan mode at low load

At light and medium loads the cooling fan stops completely, giving near-silent operation in noise-sensitive environments. The fan spins up only when thermal demand rises, so sustained output remains stable without constant airflow noise. This behaviour suits always-on kiosks, digital-signage players and quiet office workstations.

Questions about this item

What does the 100 W rating mean when the unit is installed in a system?

It can deliver up to 100 W of continuous power to the components, drawing less from the wall thanks to 80 PLUS Gold efficiency.

How does the ATX form factor limit where this supply can be used?

The ATX size fits standard ATX cases and motherboards; it will not mount in SFX or TFX chassis.

What physical space and mounting points does this power supply need?

It requires a standard ATX cut-out with four rear mounting screws and enough depth for a typical ATX-length unit.
