500W ATX Gold Flex Power Supply

This compact 500W ATX unit delivers 80 PLUS Gold efficiency in a 1U Flex form factor. It uses Resonant LLC topology with DC-to-DC conversion for stable voltage regulation and reduced coil whine. The supply is fully compatible with Modern Standby sleep states for near-instant wake times.

Compact builds needing quiet Gold efficiency

Ideal for small-form-factor or 1U systems where space and noise are primary concerns. Zero RPM fan mode stops the fan completely at low and medium loads for silent operation. Builders requiring higher wattage, standard ATX dimensions, or modular cabling should consider other options.

1U Flex form factor fit

The 1U Flex chassis determines whether this unit fits the target case or rack enclosure. Verify the physical dimensions and mounting pattern against the chassis specification before purchase. No other single specification governs compatibility as decisively.
