How To Shortcircuit A Atx Power Supply.


It is very easy to go over your intended voltage if you don't take that into account. The newer ATX12V pin outs and colours are given in the following table for reference. 24-pin Molex ATX Connector Pin outs of the 24-pin connector with their respective colours of Firstly and more importantly before you start to convert ATX PSU, make sure that the PSU is unplugged from the mains supply and discharged by letting it sit unconnected for several This sw goes to a ckt on the MB (powered by the 5V that is on all the time unless you turn the main sw off or pull the plug). check over here

Different ATX standards have different emphasis, older ones put most of the power on 5V line, nowadays its almost all on 12V line. + AT psu will be 200W max, using Looking for the latest from TI? In fact, I don't believe I've ever run into a serious issue related to RF interferance from a switch mode PS. this load can be 10-ohm,(10W) to 33-Ohm (5W).. find this

thanks for all the tips. But the higher the voltage you run the faster you can run before the current starts to drop off. If you found one it'd spit dust out of its electrolytic capacitors when you turned it on. Is there?

  2. Proper power supply construction and filtering makes it a non-issue, as any respectable rig has some PSRR too.
  3. One other option we have is to use pin 8 - Grey (Pwr_Ok) as a visual indication that the PSU has started up correctly and is ready to operate.
  4. You would need a multimeter and check voltages on each rail before the PSU shuts down to determine whether or not any rail might be dead.

Older PSUs (very old) may require a load on the +5V to produce 12V.

I have never seen a PSU without a power switch before. But if you do that be aware of RMS vs peak to peak and what that means in regards to AC transformers and DC rectifiers and filters.

Turn On Power Supply Without Motherboard The normal operation of ATX power supplies is to immediately shut down in case of a short circuit. –AndrejaKo Aug 12 '12 at 14:11 It did trip, but not When pin 14 is momentarily connected to ground via the switch, the power supply will turn-ON. It's being clever, noticing that there's nothing for it to power, and shutting itself off.

Per the comment above, a 5 watt load on the 5 volt side will probably keep it

Not saying it not still a better buy, but it is certainly not the same price. http://marcomiltenburg.com/2011/09/18/how-to-test-an-atx-power-supply/ Well done, and thanks, I was Google-ing this problem, and found your solution very helpful!.

did that but make a weird noise and gives only 5v i need 12v now what?

How To Turn On A Computer Power Supply By operating the PSU beyond its specifications, you are at best shortening the lifespan of the power supply.

But I suddenly remembered what was said about the capacitors not having a load to determine..

Do I have this correct though?
