The PS_ON# signal (green wire, pin 16 on the\n  24-pin connector) is pulled to +5 Vsb through the motherboard; shorting PS_ON# to ground (any COM\n  pin) turns the supply on. PWR_OK (pin 8, gray wire) rises to +5 V typically 100–500 ms after\n  the rails are stable. Always design a soft-start delay into any custom backplane, and never hot-plug\n  the 24-pin connector under load — the inrush on the bulk +12 V capacitors can exceed 30 A.\n\u003c\/p\u003e\n\n\u003cul style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px;\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain board power:\u003c\/strong\u003e 24-pin ATX12V, keying matches the EPS12V socket on most\n    server motherboards used in\n    \u003ca href=\"\/pl\/collections\/allen-bradley\" style=\"color:#0056B3; text-decoration:underline;\"\u003eAllen-Bradley\u003c\/a\u003e\n    and \u003ca href=\"\/pl\/collections\/siemens\" style=\"color:#0056B3; text-decoration:underline;\"\u003eSiemens\u003c\/a\u003e\n    industrial PC builds.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCPU rail:\u003c\/strong\u003e 8-pin (or 4+4 pin) EPS12V for the processor VRM — required for\n    any modern x86 SBC.
