I’m continuously using all of my wall outlets to plug-in a USB wall wart power supply to use for all of my development boards (e.g. Raspberry Pi, Arduino, etc). Over time I needed two 6 port power strips just to have enough outlets for the USB wall wart. To address this issue, I designed a very simple 15 Power USB power supply using an ATX Power Supply.
This design is a passive USB power supply, meaning this design directly connects the ATX Power Supply +5DCV directly to the +5DCV pin of a USB connector. I was considering adding a USB charging port controller and current limiting power switch such as the TSP2511. But I wanted to keep this design simple.

######I had an old ATX Power Supply, so I just used this one. This ATX Power Supply cost around $15 on Amazon.com
######This is the ATX Power Supply with the cover off. As you can see, there is room in this ATX Power Supply to fit the PCB.
######This design doesn't use an ATX connect to save money on the BOM. So I trimmed the wires to the desired length.
######Solder the ATX wires to the designated power rail of the PCB. The voltage is labeled on the silkscreen.
######Modified the ATX Power Supply, so the PCB can be mounted
######Fully assembled 15 Port USB Power Supply.
