Server PSU for 1U racks

The TOPOWER TOP-200W1U is a 200W single ATX unit built for 1U server chassis. It targets system integrators and IT teams maintaining legacy rackmount hardware that requires a compact, standard-form-factor power source.

1U form factor with standard ATX connector

The supply measures 1.57" x 3.94" x 7.87" to fit 1U bays and uses a 20+4Pin main connector for motherboard compatibility. It delivers +3.3V@18A, +5V@20A and +12V@8A across a 100-120V or 200-240V input range. The single non-redundant design suits standalone nodes where hot-swap redundancy is not required.

Replaces failed 200W 1U units

This unit directly replaces a failed or end-of-life 200W 1U ATX supply in existing rackmount servers. The upgrade is worthwhile when the original PSU has failed or when a spare is needed for quick swap-out in a maintenance window. It is not for builders needing redundant power, higher wattage for GPU compute or modern EPS12V connectors.
