We won't be selling them until we have been able to test them on a RaspberryPi! I think that is going to take some weeks 6

Re: Convert an old ATX PSU to a power supply (for your r-pi)

One PSU manufacturer has also told me that their latest 350W 80+% efficiency PSU needs a minimum load on the 3v3, 5V & 12V rails.
Another manufacturer said their PSU needed no minimum load! When I get an RPi I will give it a try!
