Recycle an ATX computer power supply into a beefy bench tool that powers your projects. 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. These four voltages cover many common electronics needs, there's even a negative voltage (-12 volts) for op amps and audio projects.
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

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.

回收的ATX電腦電源成結實的凳子工具,權力,您的項目。該ATX板突圍路線-12,3.3,5和12伏輸出ATX螺絲端子,各由一名1.25安培復位POLYFUSE保護。這四個電壓涵蓋了很多普通電子的需求,甚至還有一個運算放大器和音頻項目負電壓(-12伏)。
一個開/關按鈕和控制電路被包括在板上,需要到ATX電源沒有修改。
特徵
注:9瓦的負載電阻包括但不焊接到電路板上。在我們的經驗最現代的ATX電源不要求在5伏軌一個顯著負荷啟動。人工負載會浪費電能和產生不必要的熱量。請讓我們知道您的經驗。
一些特殊的ATX電源提供-5volts,但絕大多數沒有。我們打破了出來,並添加保險絲,但沒有填充螺絲端子。
