I understand the Deskmini B660 comes with a 19v 120-150w power brick depending where bought. My question is what is the voltage range that this board can run at. I'm wanting to build a nuc sized portable gaming rig and require more than 300watts to power this board with the board fully loaded out with an I5-12600k, CPU fan and a fractal design 140mm pwm fan, 32gb 3200 xmp certified ram, 1tb intel optain nvme, 2x2Tb Seagate barracuda Hdd, and a WIFI 6e bt 5.2 card. And the ability to run a 2060 mini. I am designing my own case to house all of this and its smaller than the deskmeet. What are my limitations on voltage input for the board? I found a 3x5" 18v 500w open air power supply that can put out a max out at 18.9v +/-3% with a voltage adjustment screw. Plan is to run 2 plugs into the back of the pc. 1 to the mb and 1 heavier gauge for the 12v converter built into the case for the gpu and other small items.

>Supports 12th Gen Intel Core??Processors (LGA1700), up to 65W

That processor Base Power is 125 W so no to that CPU.

It comes with a 120W/19V Power Adapter.

It has an M.2 slot for wifi.

Its a B660 board so it uses 12th gen and they advertise i9 usage. I know it says base is 125W but a processor idle or light games never use the full 125W. And I choose the I5-12600k over the I5-12400 for the better igpu. The 65W is hardware and Bios limited with small short burst allowing it to hit ~115W Power Draw based in articles and reviews from their other stx boards. keeping it cool shouldn't be a problem with as much cool air I'm shoving into this small case I designed.

I know it comes with a 120W brick but I want a more power to run a external GPU (2060Itx/3060 ITX) off of 1 brick (400-450W SPU) to run everything and the egpu, even if I have to get a 24v brick, the 19v and 12v dc to dc conversion is easy enough I even designed enough room inside the case for that purpose.

I know it has the Wi-Fi slot, that's why I said I wanted to run a Wi-Fi 6e/ BT5.2 Intel chip.


The original question was what are the Voltage requirements for this board. I know it takes 19V,but what is the voltage range this board can run on? (18.5-20V)? Or straight 19V?

No one on the forums here likely has that info and I doubt you will get a reply
from ASRock. I would ask via support ticket here:

https://event.asrock.com/tsd.asp

When ASRock does reply here it is usually to threads where users have issues.
