Flex ATX 500W Server Power Supply

This YINGHUA Flex ATX unit delivers 500W of continuous power in a compact 1U form factor. It is built for small-chassis servers, POS terminals and thin ITX builds where space is tight. A built-in cooling fan and full modular cabling keep airflow tidy inside restricted enclosures. The supply is rated for 24-hour operation at 40°C ambient temperature.

Suited for compact server and POS builds

Integrators assembling 1U rack nodes, Flex-ITX workstations or point-of-sale machines will fit this supply without modification. The 161 mm depth and 40 mm height match standard Flex ATX bays. Builders who need redundant power, hot-swap capability or higher wattage for multi-GPU configurations should look at larger form-factor units instead.

500W continuous at 40°C

The defining figure is the 500W continuous output guaranteed at a 40°C operating temperature for 24-hour duty cycles. This rating confirms the unit can sustain full load in the warm, confined spaces typical of 1U chassis without derating.
