Ultra compact GAN ATX power supply delivers up to 250 Watts
$145 is pretty steep, and I&#x27;d like to see the Vpp (also called ripple) before considering this. I currently use picoPSU (ASIN B005TWE5E6), 50W and 80W versions to power 7th and 8th gen atoms and celerons. I use a &quot;UPS&quot; style 12VDC PSU connected to a fairly large sealed lead acid battery - about 4x the volume of a standard UPS battery. As far as my measurements go with the induced noise from the PSU for radio reception work, it seems to work pretty good. I&#x27;ve looked at using SBCs instead, but you&#x27;re never really going to get away from buck&#x2F;boost on boards, since some things need 3.3 or less volts (memory, etc). The picoPSU also have survived for years up in elevator attics with all of the machinery and dust. never had an outage caused by the picoPSU or the attached 12V UPS stuff.<p>I wonder if it is possible to run more than one board off the same PSU. I know you can run a board off multiple PSUs, but is the inverse true? If i ever get a new batch of these 25W TDP computers racked, having 2 of these connected to two UPS and 6 computers might be cool. It&#x27;s just the ATX connector that needs population, i use NVME whenever possible, no GPU, no cards, just USB and ethernet onboard.
