I want to power a Raspberry Pi and a set of speakers from one power supply. I thought about uncasing the existing power supplies and connecting them to a power connector but that seemed a bit dangerous? I then found a HDD power supply that already provides 5 and 12v.
I guess this is a normal female molex connector that I could then plug to a male connector and then connect to the cable with the connectors for the devices on? A bit like the (rough) diagram below?
Also the power supply puts out the voltage at 2A but I need it to be at 1500mA and 500mA for each device. Any suggestions how to do that here? Its been a long time since my high school science so please forgive the "basicness" of my question.
