DC power supply | SMPS for 12v upto 14 amps


This is about how you can use an SMPS (PC ATX power supply module) to get 12 V upto 14 amps output. I was in need of a relaiable power supply for my Hyperion EoS 5i DP charger and the smps I had (12V 2Amp) became useless when I wanted to use it to charge LiPo's of capacity >2000mAh. So I got myself a PC ATX SMPS and it works great and can supply upto 12V 14Amps.Got on to the internet, pulled out the pinout details for the ATX and the power supply was ready in minutes. Here are some details.ATX-1 Shows the pinout of the 20 pin connector. The commonly available PC ATX SMPS has a 4 pin connector attached to the 20 pin connector. This is removable. Read the pin out based on the main 20 pin connector.1) Short the pins 14(Green) and 13(Any ground: Black)2) Use Pin 10 (Yellow: +12V DC) and Pin 3(Ground: Black) for 12V DC power supply.
