Hello
Have this DELL Z930P-00 server power supply, that when connected to power, not start. i hear BZZZZZZZ sound and after about 10seconds relay flips and main power works. when i disconnect it from power and reconnect it, it start imediatelly.
looks like bad capacitor. i buy cheap ESR meter from aliexpress but it show me that all capacitors is ok.
