Adaptertech make quite a few small GaN bricks. But they focus on OEM/ODM with high MOQs so it's hard to get one as a "normal consumer".


If 19/20V is an option for you, there is a pretty affordable small 230/240W GaN brick made by SAVAGO. Could be combined with a wide-volatage DC-ATX / stepdown converter...



here is a review / teardown:


Interesting!

I just found a bunch of Gan power supplies available to buy. One of which is 300W, 12V 24A out. https://www.digikey.com/en/products/detail/cui-inc/SDI300G-12-UR-P219/15189201 . Only problem is they cost a lot $$$$.

Looks like Dell is shipping a 330W GaN charger with their newer Alienware x17 R2 laptop.
You can see it just after the 1m and 30s mark here.

It looks pretty tiny! And a good replacement for the old 330W beast of a brick!

Some threads online claim that Dell will have it available for separate purchase in May 2022.

I've been trying to find one of those for quite some time now but most shops I know of only sell the 240W GaN version.

Btw, here is a teardown of the 240W DELL GaN brick


oh, if someone needs a 19V / 660W brick, I found something on TaoBao:

@REVOCCASES

Saw one sold on ebay, here. So, I reached out to seller. He very kindly sent me this taobao link.




I actually can't seem to signup for taobao. So the link is dead to me. Can anyone with a taobao account verify if that link is legit?
Worth ordering? Mind taking a look @REVOCCASES ?

nice find! I was always searching specifically for the 330W version so I guess this didn't pop up in the search results...

no guarantee - but it looks the shop you linked is legit and has a good reputation. however, personally I will pass on this for now. The premium to pay for 330W vs 240W is a little bit too much for my taste :\

If there was a 300W 12V GaN wall charger that handles high ampere, then our 12V DC-ATX builds are suddenly very attractive. The one mentioned above is 19.5V though, didn't see a 12V on that store when I looked before.

Just posting a small update on this topic:

1) SlimQ will release a 330w Gan charger with usb-pd ports + what appears to be an XT-60 plug which is then adapted to DC barrel. The 240w was a little over $100 usd after discounts, so i'm guessing the 330w will be about $150.

2) The Dell 330w GAN charger for Alienware x17 r2 is supposedly being sold independently. I can't find it on Dell's website but it is all over Ebay for $239. Which is pretty exorbitant.

sorry for the necro.
it was available for $139.99 for a few days at Dell but now it is back to $162.49

of course (?) it will need the hack to make it work e.g. with HDPlex 400W dc-atx. without the mod it turns off right after connecting.
