I have a computer power supply, how to use it to change the power of other electrical appliances? 12V.5V must be. It has a lot of lines above, what color represents what the meaning? And then why is I connected to the power after the basic line basically no voltage output? Is there a thread that controls the output of the power supply?
If the power supply is exhausted, it can be converted to multi-power supply mode. Computer power There are multiple power supplies available:
1, + 5V (red line)
2, + 12V (yellow line)
(Laptop fans use + 5V or + 3.3V).
3, + 3.3V (orange line):
4, + 5VSB (Stand By, purple line):
5, pay attention to the ground wire for the public grounding point on it.
5, PS-ON (green line):
Responsible for the operating system management power switch, is a motherboard signal, and + 5VSB together referred to as soft power. Less than 1V when the power is turned on, greater than 4.5V when the power off, the realization of software switching machine, the network remote wake-up function (set wake-up time, through the keyboard boot) (and GND then short-circuit can start the power supply)
6, -5V (white line):
(Negative voltage rarely used, such as SFX removed -5V)
7, -12V (blue):
PG signal (Power Good, gray line, + 5V signal (+ 3.0 ~ + 6.0V)): before the system starts, the power supply (0.1 seconds to 0.5 seconds after the power is turned on to issue the signal) for internal inspection and testing, To the motherboard a signal, so the power is controlled by the power supply on the motherboard monitoring components. PG signal is very important, even if the output is normal, if there is no PG signal, the motherboard still can not work; if the PG signal timing is not right, will open the machine.
There is a control power to open the line: that is the root of the green is the switch line, you and any one of the short black on the line! The The
1, + 5V (red line):
Convert a variety of logic circuits.
2, + 12V (yellow line):
Drive the disk drive motor and all fans (Exception: Laptop fans use + 5V or + 3.3V).
3, + 3.3V (orange line):
For the CPU, motherboard, PCI (Peripheral Component Interconnect external device interconnection) bus, I / O control circuit power supply.
4, + 5VSB (Stand By, purple line):
Responsible for the start of the remote power (greater than 720mA, the motherboard starts as long as 0.01A).
