FINSix, makers of insanely compact laptop chargers, made an appearance at CES. There were mentions of new products in the pipeline, but not much more than that! ...

SFF.Network FINSix Charging Away at CES

I'm actually really excited to see this finally coming to the market. It's great to see that we can now get laptop power adaptors that are half the size and a third the weight with any compromises in performance. The added USB port is also super nice.
I've been in contact with FinSix for the past several months and hopefully the next project on the table will be a much higher wattage implementation of this technology. I'm rooting for 450W, at < 0.25L (1/4 the size of SFX-L) if the size reductions are in line with what they claim.
Yeah they've been pretty tight lipped with me as well. That being said, I've talked to both them and Transphorm USA about GaN power supplies for AC-DC conversion. They both told me independent of one another that I could expect a 75% reduction in size of the AC-DC unit by using GaN and efficiency in excess of 95% regardless of load (efficiency curve is for all intents and purposes flat regardless of % load). Combined with a 95% efficient DC-DC solution, you're looking at performance that rivals or exceeds 80 plus Titanium. This is absolutely amazing technology.
Yep! That way you can quickly charge your USB C and your non USB C phone without additional dongles
That sounds ridiculously awesome! I'm just hoping that pricing will stay manageable. Maybe this'll mean that we can finally switch away from DC-DC PSU + AC-DC external blocks for super small SFF PCs without compromising on performance .
Right now the cost is prohibitively high because it's new tech. Transphorm USA actually sells a development 250W PSU that would work incredibly well for our sort of applications, but it runs between 400 and 500 USD depending on volume. That being said I presume each one is hand assembled by someone of high technical know how which means labor costs and expertise are probably a large part of that.
Would love to see an AC/DC 12v PSU that is 25x50x150mm that can handle 300w passively. Then i could fit it right in front of the motherboard on a S4 Mini. Don't even need it to be ATX, just a single 12v rail.

You could get close with one of these: http://www.vicorpower.com/ac-dc/converters/isolated-ac-dc-converter-pfc *
Get one that outputs 24V and run that to the upcoming 160W direct-plug unit from HDPLEX for the motherboard. It's $200 though.
*some assembly required
Yes they are. It will be called the HDPlex Plugless DC-DC 160 or something along those lines, but should comfortably handle up to 200W if needed. Input voltage last I heard was going to be 16-24V like the rest of their lineup.
