is from 5 watts to 100 which can make charging or using high power devices possible.
I haven't seen a motherboard that allowed that. It wouldn't make sense for a motherboard to try routing 100W of power through itself to a USB power. Even a PCIe slow is only allowed 75W. 100W also requires 20V at 5A, while PCs only have access to a decent supply of 12V, so that means at most 60W. It also means adding all the circuitry for voltage swiching to the USB port on the motherboard. For a motherboard it doesn't make sense to support any more than 5V 2A at best. Everything else is too complicated for very infrequent use. USB-PD seems to be a thing for chargers and docking stations only and hence the adapter from silverstone is perfectly good the way it is. I don't want to have to leave my PC on to charge a device. I have dedicated USB chargers for that kind of thing that are actually good at it. -- Len Sorensen
