Hi All,
Long time lurker, newbie member and SFF builder. Been wanting to do this build for a while and now it has become somewhat critical professionally because of the amount of 3D modeling work I need to do. (autodesk stuff that requires cpu threads and gpu ram more than high frequency speeds.)
Short story:
I need a work computer in my van and at my home, I do not need or desire to work in coffee shops (so no laptop). I am looking to setup a PSU for a SFF build that allows me to plug in to an efficient "12v" source in my van to maximize the time I can work on the vans auxiliary batteries and then unplug the computer and take the box inside and plug it into a brick adapter attached to the homes 120v.
The current build specs of the box...
-Ryzen 2700 65 watt
-Asrock Fatal1ty B450 Gaming-ITX/ac 30 watt?
-Crucial 32gb ddr4-3000 cl15 (two 16gb sticks) 10 watt?
-Samsung 960 evo m.2 2280 3x4 250gb 5.3 watt
-Zotac gtx1060 6gb mini 120 watt
-231 watt maximum draw
option 1:
Currently planning on running two picu psu 160xt's connected by an ADD2PSU adapter. One psu for mobo and one for gpu.
In the house I would be powering both pico psu with a single 240w 12v brick. (does that sound reasonable?)
In the van my power source would be a 12v deep cycle battery>running to a buck converter with specs of 20amps and input voltage range of 6v-to-20v and an output of 12v.
( This is a 15amp unit similar to what I'm looking for as a 20 amp buck converter https://www.amazon.com/dp/B01GFVI6R6/?tag=theminutiae-20 )
Option 2:
Run M4-atx 250 psu from mini-box instead of the two 160xt pico's. This appears it will run fine on the van's variable voltage AND on a 240w 12v power brick. Is that assumption correct?

It seems this would run fine on the deep cycle batteries in the van with no buck converter or anything in between (other than a 20amp fuse for safety). Maybe I should still run a buck converter just to make the m4-atx psu do "less" work converting voltage?
I'm VERY open to thoughts and opinions. I'll also post the final functioning build here since after searching I don't think anyone has posted a diy for a SFF that runs on 12v source in a vehicle AND on 120v/12v brick adapter in a home.
p.s. I'm very open to the option of underclocking both the cpu to 45watts and the gpu to 1050ti ish wattage (if that's possible) I'd actually love to have a setting like this to switch to when the vans battery drops to low.
Thanks for any input and ideas! Cheers!
