PSU Wire Colors?
It's rated to produce 21A at 12V, which should yield 252W. Name *Not Required Email Address For Follow Up *Not Required Write Your Feedback Here Thank you for the feedback! The original designers of the PC thought this was a very conservative system that would ensure freedom from power supply problems, but I will explain later in this article, problems can The wires remaining in the power supply should be left long and cut to length as needed.
DreadPirateZed For power supplies with a minimum-load requirement, how about lights (LEDs or older low-voltage incandescent bulbs) in place of the power resistor(s)? All psus have a standard and all the wires, regardless of colour do the same thing jclark43Aug 15, 2013, 1:51 PM Why do they have orange as 3.3volts, red as +5 Connecting this wire to ground (any black wire) will allow the power supply to turn on. We can't guarantee a response to each submission, but we promise to think about every one.
Power Supply Color Coding Diagram
Other users may want combinations of +3.3 V (ORANGE), +5 V and/or +12 V if they are converting one of the newer supplies. You generally only need to connect a wire from black (ground) and yellow (+12V) to the RepRap. Sometimes they are keyed so they only plug in one way and sometimes they aren't. A motherboard which has the 8 pin EPS connector expects a lot of current and you are taking a serious risk by plugging in a 4 pin cable.
The adapter will no longer produce sufficient voltage. Increasing the resistance makes the connector drop more voltage and dissipate more heat. I used a toolbox to put the psu in, and bored holes in the removable tool tray to hold the binding posts. Power Supply Color Rating I didn't even have any speakers connected to the stereo when I connected the power supply to it, yet the power supply shut off immediately.
Besides, the stereo should only be drawing its maximum power at its highest volume setting during the loudest portion of music. How To Use A Computer Power Supply For 12 Volts Boy, those were the days. Any suggestions?
Hey, that's a great build! When in doubt, use duct tape.
In very rare cases, you may also have minimum output requirements on the 12V pin and the 3.3V pin. Computer Power Cable Color Code ATX PSUs which are specified as "Haswell ready" should never have this problem. wires that exit the PSU and end in connectors). It pulls a lot of power.
How To Use A Computer Power Supply For 12 Volts
See the Table of Representative Current Levels for other power supplies. This design for an external adapter lets you use the power supply without modifying it. Power Supply Color Coding Diagram But since 4 pin peripheral connectors only supply 5 and 12 volts, the SATA connector is missing 3.3 volts (there's no orange wire). Smps Wire Colour Code And Voltage Pdf But you should avoid using that kind of adapter if you can because the extra wire and connector are just more things which can go wrong.
Do you see any problems with my pc running this board? I will also disassemble the fan and lube the bearings while I have the PS open. I used a small push button switch to make this connection. Pinout Pin number Wire color Description 1 red +5 volts 2 black ground 3 black ground 4 yellow +12 volts Connector part numbers Socket housing Socket Maximum current per circuit AMP What Is The Voltage Of The Blue Wire
- It is a HP model p6228p.
- Modifying a PC Power Supply for general (RepRap) Usage This is required for cases where your electronics is not prepared to use unmodified ATX PSUs.
- If you are drawing too many amps then it could shut the supply off.
- Insert the post of each terminal into the holes and tighten them in place with their screws.Step #8: Connect Spade Terminals to the End of Each WireNextPrevThe output terminals need to
- Is there a way to take a few of these power supplies and hook them together to run the amp?
- Please don't compound any stupid design already built into the power supply, or you might regret it!More CommentsAbout This Instructable 153,603views316favoritesLicense:LynxSysFollow47Bio: I'll tinker with anything, but I'm often to be found
- Typically, PSU voltages should be quite well regulated.
- Alternatively, connect a switch between the green wire and a black wire, and this will be your main RepRap power switch.
- If you can't figure out the issue, I would suggest that you find a different PSU.
Good sources for a serviceable (and free) unit might be the old computer and
All the adapter does is remove the problem from the 24 pin motherboard connector and move it to the 20 pin connector on the adapter. Step #5: Glue the Female ATX Connector to the HousingNextPrevTo hold the main connector in place, I used 2-part JB Weld. Access Point ? Then I drilled holes that where just big enough for the mounting screws.
That’s unfortunate because power supplies are not all that complicated, and they are often the cause of puzzling, tough-to-troubleshoot problems. Power Supply Connector Diagram So we had a massive stack of ATX supplies looking for a purpose.

John Ellsworth I really like your take on using a motherboard connector to make this work with with any (atx) power supply.
The original 20 pins were unchanged. While most heatsink compounds are rated to 160 to 170 C, some may dry out over time and their effectiveness will diminish -- a periodic check for good contact between the Step #12: Add a USB Power Outlet (optional)NextPrevAnother optional connector that you can add is a USB outlet. Computer Power Cord Wire Colors The PS has some fairly hefty electrolytic capacitors and can still give a bit of a shock immediately after being unplugged -- let it sit a couple of minutes before poking
This compound comes in two parts; squeeze out an equal amount from each tube, then mix them together thoroughly.

DO NOT work on your opened power supply with it plugged in!!!!
Step #13: Add Labels For Each Pair of TerminalsNextPrevTo help keep track of the different voltage outlets, I labeled each pair of terminals. These numbers represent the maximum for each component; the actual amount of draw will likely be less.Motherboard—5 amps of +5V or +3.3V and .7 amps of +12VISA circuit boards—2 amps of Install the 10 ohm 10 watt pre-load resistor between DC ground and the +5V rail (red). Read these TIPS for some options that may help increase this voltage level, provide a little theory, identify the connector pinouts found on most PC supplies and give a few troubleshooting
smeezekittyAug 16, 2013, 11:47 AM No problem. The 24 pin cable plugs into one end of the adapter and then the adapter plugs into the 20 pin motherboard. Solder Wires to the Female ATX Connector3. But if you split the connector into two parts then you can plug the 6 pin part into the older 6 pin PCI Express connector and leave the 2 pin part
