7 watts idle – building a low powered server/NAS on Intel 12th/13th gen

Oh this is pretty interesting, thank you very much. You mean that the Bojiadafast adapters work fine?

If so, I wonder if there is a hit in efficiency because of the required step-up / step-down converters in that adapter.

However, on my board there seems to be an unsoldered 24pin connector, that could be just used as is with a little soldering, but since it is on-hold my replacement system if my ...-B variant dies, I'm not willing to risk too many experiments :-)

I have no experience with this particular vendor/brand but the adapters are not complex. If you're concerned, verify that it has 11VSB before you plug it into the motherboard. Otherwise it's entirely passive (passing through PS_ON#, PWR_OK, and 12V)

It should be quite nominal. The boost converters have a very high efficiency (>85%) and standby power is typically below 10W max.

Cool thank you... I also thought about soldering a 2$ female 24pin plug to the spot where it is on the (-B) variant... seems that they just left the plug out but the connections are there.

We'll see :-)
