- A fact that standard PC power supply is very cheap. The new PC power supply will cost you about US$10 – US$15, but a bench lab power supply cost you about US$ 100. You may use your unused old computer power supply
- Has regulated and very stable output voltage (+/12,+/-5, +3.3VDC general)
- Has very high current DC current output
- Has a “box” which very easy to modified
By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and very tight voltage regulation. Take a note that you should have good grounding connection for best performance output. It might be causing “hum” for audio circuit if you have bad grounding system/connection.
