EDIT 12/1/2020: I have not updated these lists in years, and they were created before I/we had a better understanding of CPU power delivery. I am not an electrical engineer, and these were born out of a hole in the communal knowledge that I wanted to help fill. In modern times, these lists should be viewed as a historical record of interesting discussion. For actual VRM info on current boards I HIGHLY recommend Buildzoid of Actually Hardcore Overclocking on YouTube. This man is actually qualified to dispense advice on motherboard power delivery. I greatly appreciate the time, effort and discussion that everyone contributed in making these lists. I believe we helped to change the discussion around power delivery, particularly in the AMD space. MSi appears to have really changed their ways. As someone that burned down multiple 990/890FX MSi boards, this is all I could have ever asked for.
In light of xd_1771's thread (here), I (and xd) have decided to start making a list of AMD motherboards and their power phases.
Can't find your board on the list? Submit it, and we might be able to add it!:

Note 1: all un-heatsinked boards will support Enzotech MOS-C1 heatsinks
Heatsinks referred to in spreadsheet:
Enzotech MOS-C1
Enzotech MST-66
Enzotech MST-88
Note 2: Often when a board is advertised as 8+2, 16+2, etc, it often still uses 4 channels. There has been some controversy over the advertising of "8+2" phase boards since they are not true 8 channel designs. But, since 8+2 (with four channels), in most (read: not all), situations is much better than 4+1 (4 channels) we still decided to list them by their Phase count rather than their number of channels.
Note 3: Please be aware that just because a board does not have something the "recommended" collumn does not necessarily mean it is a bad board. It can either mean no-data, or not-recommended. As there are hundreds of AMD motherboards, we do not have time to research every one. If you have a question about a particular board, make a thread, or post in this one.
