About this tag
The ATX connector is the main power cable from a power supply unit (PSU) to a computer motherboard. In troubleshooting a Lenovo ThinkCentre M52 that won't power on, a user tested the PSU and found that while the ATX plug tests good, other connectors do not. The question arose whether case fans should spin with only the ATX connector connected, without the motherboard being powered on. Typically, fans will not spin unless the motherboard sends a signal via the PSU's control circuit, so a lack of fan spin with just ATX power does not necessarily indicate a bad PSU. This tag covers discussions about ATX connector testing, PSU diagnostics, and power delivery issues in desktop PCs.
