Standby LED should illuminated indicating the ATX power supply is in standby mode. I had my ATX on my working bench serving as a power supply, but with a lot of messy wires comming out, so i decided to mod it to have 5 output only: GND, 3.3V, 5V, 12V and -12V I also wanted to turn it on and off when necessary so I need a power switch And of course a LED for Power BB-ATXRA, the breakout board for ATX power supply from Cytron. How much electrical current does the supply provide? 4 years ago, keep yellow and black wires that you bundle together seperate.. yellow wires are +12 volts and blacks are the ground or -12vdc. files 1 project box/ tupaware container $ 5 (at jaycar) I know I can wire the gray POWER_OK to a resistor and ground but it would be nicer to just use a lite switch. Bear in mind, never short those connections bottom of BB-ATXRA, you will short the terminal and most likely damage the ATX power supply. We are going to utilize it as the power source for our project and development. Once again sorry for the picture quality. This topic is one of the more popular of all instructables. All I want to do is run a Dual PC amp off one power supply without cutting off from too much wattage used. Burn - In OK this is a BestTec PSU and my other one just in case is HiPro PSU. on Step 8. this atx power supply has 1 led on back 120/220 switch and plug for ac no on off switches? BB-ATXRA come with ready connector and other supporting components such as atx power supply led lights when i plug it to wall but no volts out why??? Just a note to let you know I have added this instructable to the collection: Encyclopedia of ATX to Bench Power Supply Conversion >> https://www.instructables.com/id/Encyclopedia-of-ATX-to-Bench-Power-Supply-Conversi/Take a look at about 70 different approaches to this project. Just turn it on and hook up a multi meter to be sure it's working. on Introduction, 6 years ago Now just pull the power supply out and your done. Let me leave the current rating at the back. Make Your Own Colourful Plate for Your Home, 4x4x4 LED Cube using Arduino UNO without extra IC. (I did it to black, red and yellow). Now, activate the toggle switch on BB-ATXRA, the PWR_ON LED should illuminate indicating the power is fine. I have two ATX power supply in my lab. Did you make this project? Then, insert a trimmer before the regulator, in order to lower the feedback voltage, so the regulator is tricked into raising the output Max Hi Pot OK 250W Max example of atx power supply hack header pin with female jumper wire https: //www.instructables.com/id/Encyclopedia-of-A a!
