Product Description
SeeedStudio - ATX Breakout Board Bench Power Supply Computer - DIY Maker Open Source BOOOLE
- 1)The ATX breakout board routes the -12, 3.3, 5 and 12 volt ATX outputs to screw terminals, each protected by a 1.25 amp resettable polyfuse.
- 2)Optional load resistor included but NOT soldered. Open source (CC BY-SA). Note:A 9 Watt load resistor is included but not soldered to the board.
- 3)These four voltages cover many common electronics needs, there's even a negative voltage (-12 volts) for op amps and audio projects.
- 4)Recycle an ATX computer power supply into a beefy bench tool that powers your projects.
- 5)On-Off button and control circuit
An on/off button and a control circuit are included on-board, no modifications to the ATX supply are needed.
Features:
- 12, 3.3, 5, 12 volt supplies @ 1.25 amp
- 1.25 amp polyfuses with reset on each power rail
- Indicator LEDs show that each rail is working
- Power good and enabled indicator LEDs
- On-Off button and control circuit
- Optional load resistor included but NOT soldered
- Open source (CC BY-SA)
-
Note:A 9 Watt load resistor is included but not soldered to the board. In our experience most modern ATX supplies don't require a significant load on the 5 volt rail to start. An artificial load just wastes electricity and creates unnecessary heat. Please let us know your experience.
- Some special ATX supplies provide -5volts, but the vast majority don't. We broke it out and added the fuse, but didn't populate the screw terminal.
