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!:
>>Click Here for Submission Form<<

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.

Is there any chance you could put down a note to say if a motherboard is mATX or not? It's near impossible to find decent mATX AM3 motherboards.

We can put a note for mATX at a later time. For now, we are just working on getting it all filled in.

We should have it done in a few days

My board:
Gigabyte
Ga-870A-UD3
8+2
None/Upgradeable (Note: mosfets and pushpin holes are arranged exactly for a Enzotech MST-88)
140W
Not sure
Not sure

8-pin

2nd Note: Standard gigabyte extra thick copper plane aids cooling.

Same here and I have the same Enzotech MST-88.

The Enzotech MST-88 also fits on the Ga-770A-UD3.

This is a good idea. This should be added to the motherboard threads & clubs sticky.

Wow, such a great idea. That would help users a lot, especially when trying to decide on a board to buy.

Add ASUS M4A89GTD PRO/USB 3 for 8+2 Phase. 140w and has 8-pin plug.

I like how a lot of you are trying to help with your own info

I'm making great progress in the Gigabyte area, both sides learning quite a bit here. This is fun

AM3+ soon enough!
we will be making a separate spreadsheet for AM2/am2+ and AM3+ when it officially comes out.
