TFX12V Power Connectors
The TFX12V Main Power Connector uses the same pinouts, wire colors and sizes, and physical connectors as the ATX Main Power Connector shown in Table 26-12, with one exception. Pin 18 (-5VDC) is not connected on TFX12V power supplies because -5VDC is required only by ISA expansion slots, which are not supported by TFX12V systems. TFX12V power supplies also include the ATX12V connector described previously.
