Q: the pictures of this case on the CoolerMaster site looks like there's a USB-C trigger to a Coaxial power connector, then another connector to the mainboard itself. Would this case work with a 20v coaxial power supply?

Q: What voltage/wattage does the Framework SFF computer need to power up?

A lot of the USB-PD power supplies only give watts, not the voltage provided. Your 60w power supply is probably either 12v/5A or 20v/3A, but the page itself doesn't say: https://frame.work/products/power-adapter

I have some 15w USB-C 5v/3A power supplies (that won't charge my Sony camera), a USB-PD battery that supposedly puts out 12v on the one USB-C port, and an Apple 30w USB-C ac adapter. My 2016 macbook charges on 5v, which is convenient. Framework forum posts indicate the laptops will charge on 5v 12v and 20v, but there was a problem with 15v.
