    The author posts here. I hadn't seen that article before myself. It's an interesting approach, and their design is a clever use of feedback.

    It's not really what I would call redundant (Redundant Array of Inexpensive Powersupplys = RAIP? :worried: )

    One of the main things you want from your PSU is regulation (the voltage should show only small changes under large changes in load current) and I think the design they went for sacrifices regualtion at the expense of increased output current. They didn't load or do anything at all with the +5V rail and that's where the feedback that accomplishes regulation is usually drawn from.

    Very intersting read though, I applaud their effort.

    Yes, he does :p

    Actualy, someone on the procooling forums and I are working on designing a redundant PSU setup for him. This circuit is NOT designed with redundancy in mind, as this has been requiring quite an extencive redesign.

    There may be another article posted on redundancy, but more than likely not by me ;)

    linear, just make sure you don't get caught saying that acronym around any women.

    "Yeah, my RAIP setup is great right now. I just go back there, in-out and my baby doesn't even know anything happened."

    /me waits for inevitable headline "CACK: Computer Acronyms Can Kill"

    That is very good read :eeek: No wonder why the hot-swap redundant PSUs are that expensive!
