Supply of high quality ATX power cable

ATX power long as it gets the power is turned on the line, but now the ATX power supply is the potential control switch instead of a mechanical switch, which need to find out from the investigation that line the hole can activate the power supply pin (Pin). ? ATX power supply pin (Pin) is defined as ??? no standard definition of each line start --ATX motherboard power supply connector (20-pin and 24-pin have)? AT power supply as long as the power is turned on the line can be ATX power supplies are now potential control switch instead of a mechanical switch, which need to find out from the investigation that the power line hole can activate the power of the needle (Pin). ? ATX power supply pin (Pin) standard is defined as:?? 14-pin (?? Pin 14 PS-ON) is to control the power is turned off. Single needle is not how the control switch circuit, in fact, all of the ground (GND) circuit and can be composed of any other needle, the so-called "low potential" open "high potential" closed, that is, when Pin? 14 needle with? GND? Pin short After then, Pin? 14 potential needle itself is low, the power will turn on, and vice versa. Now very clear - in order to open the ATX motherboard without power and need to Pin 14 pin (green line, the figure also marked green) and any one of GND pin (black line in Figure winning gray) can be short-circuited? . ? Red Red = + 5V? Orange Orange = + 3.3V Yellow Yellow = + 12V Blue Blue = -12V Green Green = PS_ON Purple Purple = + 5VSB gray Gray = PWR_OK white White = -5V Black Black = COM = GND = Ground 20-pin power each pin definitions: Since January 1998 published ATX2.01 power standards, the future power production are compatible with this standard, but the brightest voltage output current is increasing. ATX switching power supply voltage, the output we have used several different voltages + 12V, -12V, + 5V, -5V, + 3.3V and so on. Under normal circumstances, a change in the output range of voltages tolerance generally within 5% in the following table, there can be wide fluctuations, otherwise easy to crash the data loss situation.
