What is the wire color coding of ATX computer power supplies puter power supplies (PSU) convert AC to low voltage regulated DC power. Most modern desktop computers conform to the ATX standard, which supplies three positive rails: 3.3V, 5V and 12V. ATX power supply connector pinout diagram @ pinouts.ru ATX specification includes not only Power Supply Unit, but also interface to case and motherboard. In addition to the old AT standard, ATX 2.0 has one extra voltage line available ( 3.3V), a connector chain lined to the single 20 pin and a power on wire that allows Software to turn off the PSU. Power supply unit (computer) Original IBM PC, XT and AT standard. The first IBM PC power supply unit (PSU) supplied two main voltages: 5 V and 12 V. It supplied two other voltages, −5 V and −12 V, but with limited amounts of power. ATX Power Supply Pinout and Connectors Peripheral power connector goes to disk drives, colling fans, and other smaller devices. There may also be a floppy drive cable. Note that the wire numbers in Serial Power ATA (SATA) connector are not 1:1. There are three pins for each voltage. One pin from each voltage is used for pre charge in the backplane. The mating serial plug of ATA devices contains both signal and power segments. Power Supply Connectors and Pinouts moddiy Of course, none of this helps you if your cable uses the trendy all the same color wires design which is popular with high fashion power supplies. In that case you'll just have to be very careful or hope the connectors are labeled.

ATX 24 pin 12V Power Supply Pinout Lifewire If you need to use a 24 pin power supply connector on a motherboard that only accepts a 20 pin cable, there are a number of online retailers where you can purchase a 24 pin to 20 pin adapter, like this StarTech adapter from . Though the motherboard appears to accept all 24 pins using this type of adapter, it still, of course, means that the additional four pins go unused. Turn a puter Power Supply into Bench Power | Make: The green wire is the "power on" sensor. This wire is internally connected to 5V with a pull up resistor. If you connect this wire to ground (any black wire) the power supply will turn on. The purple wire is the 5 "stand by" power. This outputs a 5V signal even if the rest of the power supply has not yet turned on, allowing you to power any circuit that might control the ON OFF signal. A Maker's Guide to ATX Power Supplies: 6 Steps There are tons of Instructables on how to hack a discarded ATX (computer) power supply unit (PSU) into a lab bench power supply. This is not one of them. DC Power Supply from ATX power supply I use the DC power supply to charge Li ion batteries scavenged from laptop power packs.

Convert an ATX Power Supply Into a Regular DC Power Supply! The green wire is what tells the power supply to turn on from stand by mode, we want to just solder it to a ground (black) wire. Put some heat shrink on this so it won't short out on anything else. This will tell the PSU to be constantly on without a computer.
