How do I keep my ATX power supply on?
The PSU can now be turned on or off using the power switch on the back of the PSU. It is common for people to use paper-clips to jump the green and black wire in the same method as described above. While a paper clip will work, I highly discourage doing that.
What does ATX stand for?
Advanced Technology EXtended motherboard
(Advanced Technology EXtended motherboard) The PC motherboard that superseded the Baby AT design. The ATX layout rotated the CPU and memory 90 degrees, allowing full-length expansions to be plugged into all sockets. The power supply blows air over the CPU rather than pulling air through the chassis.
How can I convert an ATX power supply to a bench top power supply?
There are a number of ways to convert a standard computer ATX power supply unit into a usable bench top power supply. You can keep the 20-pin Molex connector attached and connect directly into it or cut it off completely and group together the individual wires keeping the same colours together, reds to reds, blacks to blacks etc.
Can a PSU be converted to a bench power supply?
The standard computer power supply unit (PSU) turns the incoming 110V or 220VAC (alternating current) into various DC (direct current) output voltages suitable for powering the computer’s internal components and with a little bit of imagination it is possible to convert ATX PSU to a bench power supply.
What kind of power supply does an ATX motherboard use?
The original ATX standard connector used for powering the motherboard was a single 20-pin Molex that has all the required +12VDC and +5VDC voltages with huge output currents and short circuit protection as well as a Power-ON wire that allows the PC’s software to turn “OFF” the PSU on shut down.
What kind of power do I need for an ATX PSU?
In the main power cables you should now have three red wires (+5V) all connected together and three black wires (0V) connected together as the others have been used for the switch and LED. Also connect together the three orange wires to give a +3.3V output if you require it to power smaller devices or micro-controller boards.
