For a project I will have 4 stepper motors,a laser module and few modules attached to the FPGA. I need around 10 amps.
Clearly the FPGA can't provide enough power for all the modules. I think to use and old 300W PSU to provide power to all the modules.
From 2 connectors I can get multiple 5V sources and connect them to different modules rather than just using an usb cable connected to the FPGA.
Can the PSU sustain all the modules?The amount of power needed is maybe a third of the power of what it could provide. The PSU being old I'm afraid that can just die randomly or make a short circuit and kill the FPGA. Is it worth it or should I try another ways to provide power to the elements?
