Compact 1U power supply for small form factor builds

This 500 watt Flex ATX unit is built for 1U rackmount servers, NAS appliances and mini ITX cases where vertical space is limited. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion delivers clean power while reducing coil whine.

Check physical clearance and connector requirements

Verify that your chassis accepts a 1U Flex ATX form factor and that the unit’s dimensions match the 39, 41 or 49 mm mounting patterns referenced in the supplier title. Confirm the cable set provides the motherboard, CPU and peripheral connectors your specific board needs before ordering.

Suits quiet, space-constrained servers and NAS boxes

Builders who need a silent, high-efficiency supply for always-on storage or edge servers will benefit from the zero RPM fan mode and Gold-rated efficiency. Systems requiring higher wattage, standard ATX dimensions or modular cabling not listed here should look at alternative form factors.
