ATX breakout board V1.2

Posted on Monday, February 18th, 2013 in ATX BB by DP


Crenn tweeted a picture of his ATX breakout board v1.2 power supply:

Got a @dangerousproto ATX Breakout Board V1.2. Hooked it up to a cheap chinese powersupply to test it out!

You can get one for $14 at Seeed Studio.

You can also get a Sick of Beige case for your ATX breakout board for $4 at Seeed.

    Got this on saturday myself, where can I get the same connectors so I can add for the two that is missing?

    Would these be the same connectors?

    Out of curiousity, have you seen power supplies where the 12V slowly increases to over 13V? I’m wondering if that’s grounds for me to need the Load resistor.

      I’ve never noticed it, but could certainly happen. I’d add the load resistor and see what happens. You may also need to load 12volts.

      AFAIK most psu need a load, either across gnd and 5v or 3v3. All the designs I saw use a power resistor in either line.

    I am having trouble getting the power supply to startup after pushing the power switch. The fan turns for a few rotations and the LEDs come on for a few seconds and then go out. I installed the 9 Watt resistor in the proper place on the PCB. I am thinking the power supply needs more of a load to start up properly. Which supply is the provided 9 watt resistor connected to? I don’t recall seeing a schematic for the breakout board.

    Has anyone else encountered this problem?

    Thanks, Sam

    Pretty happy with the breakout board.

    If you do an upgrade to it, I’d like to suggest a USB connector to power 5 volt devices. There is room on the left side, where your logo is. For example I power my breadboard and it would be nice to power the Bus Pirate at the same time. It may need a cap added to the circuit since the cheaper ATX power supplies have some ripple.
