I went looking for the specs because I was specifically interested in how that power negotiation works.
Turns out it's only two wires with plain static logic signals, no communication or anything. https://cdrdv2.intel.com/v1/dl/getContent/613768 https://cdrdv2.intel.com/v1/dl/getContent/613768 page 25.

- zelon88 5y agoVery interesting. So it says what each rail can handle. I wonder if there is any wiggle room in the spec to piggyback a proprietary signal. For example, do you think a PSU that toggled the output of one rail between two specific values between spec polling intervals might be able to indicate to proprietary software the specific brand or model of PSU?
