Using Computer Power Supply For 12v Power


Running too much amperage through a single, thin wire is a fire hazard.



question, is there any other way to ground my AUX wire? SUBSCRIBE Sign up for the Make: Newsletter Stay inspired, keep making. Make sure that you have removed the power cord before doing the conversion and have discharged the capacitors as described in the steps above. Especially
in regard to basic concepts. (Hey, I was new to this not that long ago, so I can sympathize.)

Voltage does not "flow". http://magicnewspaper.com/power-supply/power-supply-makes-clicking-noise-when-i-press-power-button.html

Working... If so, the power supply might not shut down when it is overloaded or when it begins to fail. Thank you!I have a 12v psu how can i make that into a 14v so then i can power a 14v car head unit12v is enough to power a car head Once all the holes are drilled, insert the switch and the power terminals and fasten them in place. http://makezine.com/projects/computer-power-supply-to-bench-power-supply-adapter/

How To Use A Computer Power Supply For 12 Volts

If you have wires not listed here (brown, etc), see the Tips. If you are drawing too many amps then it could shut the supply off. For example in 3.3 v i get 6.6 v on 12.v i get 24.v etc.. It might be useful to drive an LED from this as an indication that the mains are on.

Till then good luck!!!!!???

If I couldn't figure it out, I got the advice to try this instead: http://www.eleccircuit.com/wp-content/uploads/2012/09/Circuit-of-my-first-variable-dc-power-supply-1-2v-to-30v-1a-by-lm317.jpg Might be of interest to you as well.

Thanks bro....me also trying to find Converted PC power supplies may be stretched to the limit by these demands for more current. I'm definitely going to do this. Convert Atx Power Supply To 12v Input Learning slowly but surely.

So long as you don't have it plugged in while working on it you're fine. Using Computer Power Supply For Other Uses Yonian If you're ever going to use molded dual banana plugs you should space your jack pairs 3/4 inch (19mm) apart. If used as a power source for the micro and sub-micro servos, you must be careful not to drive the servo to either endpoint to avoid stripping the smaller gears in

On most power supply units (PSUs), the other lines are unregulated.

When you replace the board, make sure that the plastic sheet goes back under the board. Convert Atx Power Supply To Bench Power Supply Also, be sure you are not grounded so that remaining voltage doesn't flow through you to ground. 3 Remove the screws that attach the power supply to the computer case and This splits one 8ohm signal into two even 4ohm signals for your amplifier. I recommend using JB Weld, just like you did for the 20 pin power supply connector.

Using Computer Power Supply For Other Uses

You are responsible for your own safety!. http://www.instructables.com/id/Convert-an-ATX-Power-Supply-Into-a-Regular-DC-Powe/ I did one mistake I didn't used PCB because I considered it to be fairly simple project, but now fixing will be real pain. How To Use A Computer Power Supply For 12 Volts Loading... Convert Computer Power Supply To Battery Charger That was incorrect and dangerous.

Connect the Green Wire to the Power Switch7. If your power supply has a minimum output requirement, you can meet this by connecting a large power resistor across the output terminals. They are perfect for general electronics.This is my first Instructable for what I think is a brilliant idea, I'm only 14 and i can build itWARNING: This will void warranty's and Repeat for yellow, black, (orange if you want 3.3v) and try to avoid a fire. :o) Chris Joy Great project! Convert Atx Power Supply To Variable Benchtop

It regulates the voltages by rapidly connecting and disconnecting the load circuit (switched-mode power supply). It almost all cases, your home stereo receiver will put out a 8ohm signal and your amplifier will require a 4ohm signal. A 1/4 watt carbon film resistor rated at 180 to 220 ohms wired between either of the leads and the PSU will work nicely. http://magicnewspaper.com/power-supply/graphic-card-power-to-power-supply-or-connector-on-motherboard.html This would allow me to get the full potential via each coloured connection.

Add a USB Power Outlet (optional)13. Computer Power Supply Amps We also use the +5 to drive servos in the robotics lab. The ohm rating is simply the impedance (resistance) of a particular circuit.

You'll have to look at the nameplate for the specs.

You can also convert this to a variable voltage power supply - but that is another article (hint: Uses a 317 IC with power transistor). The result is a high capacity power supply that can output 3.3V, 5V, 12V and -12V. all yellow wires can be joined together, all orange …, etc.? Atx Power Supply Wire Colors Posted on October 25th 2016 | 5:42 am Reply P Paul Thank you, it is working!

Basically that is it, just I am not sure how to fix it. The wires remaining in the power supply should be left long and cut to length as needed. Once you have shorted the green and any black wire, the PSU fan will spin up and you'll receive power on all rails.

I made it! Jason Poel SmithMy name is Jason Poel Smith.

A supply that you have pulled may look dead because it does not have a load on its outputs and the enable output may not be grounded (green wire). Mike Simpson Thanks for this! Wiring coming off an industry standard circuit board will be: ORANGE+3.3 V YELLOW+12 V BLUE-12 V RED+5 V WHITE-5 V (May not be present on recently manufactured supplies) BLACKGND GREENPOWER-ON(Active high Other than that, works great.

Next, separate the internal wires at the end. Once the wires are connected, mount it to the side of the housing. If I connect these two lots of wires separately (ie.
