Hi,

I'm trying to hook up a raspberry pi zero to control lights/fans in a computer case without usb sockets or motherboard usb headers available - only the power supply is needed for usb, not the data pins.Before I risk hooking it up, the 4-pin molex from a PSU has a 5V supply and a ground can I use an adaptor to run a usb device?

Please help.

I didn't find the right solution from the Internet.
