Atx power supply manual turn on

Have you ever wondered what a PC power supply is? ATX refers to a second generation power supply. This device is installed on the computer and converts alternating current from electrical energy into direct current. An ATX power supply lowers the voltage so that other components of the equipment can be connected to it. In this way the devices are protected from voltage fluctuations or power supply problems. An ATX power supply allows manipulation of its shutdown via software.

Also, some models have a switch located in the back; This mechanism is used to avoid unnecessary consumption of electricity in "stand by". Generally, i modern ATX power supplies have a digital button which replaces the mechanical switch. Additionally, ATX power supplies can be integrated into old and new microprocessors. For that, you can follow the steps we explain below.

With these tools, you can take the next step. Unplug the ATX power supply from the motherboard if it has been installed in your PC and take advantage of this step to clean your PC power supply if it has a long period of use. When you have finished this job, proceed to make a bridge between wires 14 and 15 green and black wires respectively. The green wire is used to turn on the power supply when it is connected to ground, while the black wire is used for the ground function.

In this step it is necessary to use the voltmeter to measure the different voltages of the connector. Digging In — Making Voltage Measurements First, thank you Wikipedia and its contributors for placing every bit of useful information on the world wide web WWW that was once only contained in user manuals and instruction manuals. Fortunately, this free online pin diagram matches with the wiring of the ATX motherboard and power supply that is being worked on. This is an especially fortunate set of circumstances.

The power supply wants to work. This tutorial is perfect and gets to the point. I used another "Youtube" to get an old unit working with the "Green Wire" method, worked well but the unit was old so I decided to use a "less old" unit, Nope, just a quick flick of the fan. I connected the Brown wire to an orange wire, up it came. Thank you to the original poster and more so, now, the comenters.

Thanks all! Question 2 years ago. This Pwr Sply was just working. Found bad connection from Frt Pnl Switch to Mobo so fixed it but no good; still dead. Right now it's out of its case and on the shelf waiting for field medics to check it out.

Otherwise, can you advise where to get a replacement for it??? Any other ideas? Reply 2 years ago. EdwinM73 thank you SO much! Superb advice regarding the brown wire. I've been struggling with this problem for some time now, so the power supply went off suddenly since I wasn't using the brown wire!

Now it works perfectly by following your advice! You missed something important for 24 pin PSU,s. Your 24 pin psu will now work as intended standing alone.

Hope i helped you all :. Reply 4 years ago. I am also running into the same problem and landed on your response here in regards to connecting the brown to an orange connector. So I have tried this, and still the PSU will turn off as soon as I put load on the 12v 4pin connectors. One thing different though is that my pin 13, is actually brown and orange. There is two wires going to the pin. What does this mean? Does this work differently?

The pin 13 will be the orange already connected to the brown, nothing to do there. If you have connected the green to a black and it still doesn't work, try adding a small load 12v headlamp etc.
