Does that mean that all the people using i.e. a Meanwell PSU or an external power brick are consuming electricity even with their computer off?
If so, the One2 is indeed a very useful component to add.

Not really. When your PC is off, it doesn't consume much power at all.
It's just that sometimes weird things happen if you have 12V power always applied, like your GPU LED always on, or the fan is funny. It helps to properly trigger the 12V so it is only on when your PC is on.
Could this somehow be used (perhaps with an extra board) to use two AC-DC power supplies to power MB/CPU and GPU?
You can only use one AC-DC per board unless the AC-DC supports load sharing.
The issue is that any slightly voltage difference between two PSU causes electricity to flow from one AC-DC to the other AC-DC. IE 12.0V flows to 12.1V.

Sure but as @InfernoZeus suggested, you could use two boards in parallel , powered by two different AC-DC units :
- one board always ON to power the system,
- one other board triggered by the first one, to power the GPU.
- one board always ON to power the system,
- one other board triggered by the first one, to power the GPU.
I've said it before and I'll say it again, someone needs to put together a comprehensive state of the union for small form factor PSUs (AC-DC and DC-ATX, 19v, 12v, internal vs external) because this shit is way to confusing for me.
But hey, I successfully wired a new power button with LED last night for my case, so I'd call that a win.

Which is exactly how the Dynamo Combo's sync feature works
Remember, we talked about the sync issue at the very beginning of the Dynamo design stage
I've learned since then that some motherboards can react in a weird way to those switches.
For instance, my Fatal1ty Z170 ITX does not like the sync function of the Dynamo : the 5V stays always ON, sometimes the 12V rail.

That's not at 12V though, right? I'd much prefer a 12V system. Apart from that, the Dynamo Combo is pretty much exactly what I need..
Alright, some good news, and some bad news.
The good news is: the distro works very well, and fits perfectly inside the dancase. I will be making some very nice changes to tidy up the look of the board, and will hopefully get second set of prototype in a month or so.
The bad news, is the sync feature needs to be modified and this delays the development by a month as well. Hopefully that gets squared away. This mean I'm currently looking at Early 2019 for a consumer release.
Here is some pictures of it inside a build:

Revision 2 with close to final circuit.
Release is looking to be Nov or Dec.
Compatible with any 12V kit. Initial release there will be 250W external psu kit available.
For the cabling,
Would you guys like to see individually sleeved cables as the default? It'll increase the price of course. Or just simple black cables?
I'll just leave this here.

I'd vote for simple black cables, but I'm also more interested in board only than full kit so maybe the question isn't for me.

I'm not sure what you mean by that. The connectors are already attached to the headers.
Also, elr/elp? You mean mini fit right?
Here's how it would look wired up. Still waiting on the WAGO connectors. I will be receiving prototypes in about 3-4 weeks.
Pretty cute right?
I will be releasing the first 50 run as the founder's edition, for those who live on the forefront of small. After that, I will make some changes to the board as I get input from the first round of customer.
I updated the first post to reflect the correct specs.
Looks very svelte. Would it be possible to get 300-400W to EACH the CPU and GPU, with two AC-DC units, at below the volume of an SFX PSU with this sort of config?
Alright, some good news, and some bad news.
Sorry meant in the bottom left of this picture where the power source enters the case.
