We already have support for this in every OS, it&#x27;s no different than a laptop or existing UPSs. What sucks is that to work with a generic ATX motherboard without a special header to hook into the best externally accessible bus to put it on is probably going to be USB. It&#x27;s not like you would need to plug it in outside the case either, there&#x27;s usually a spare USB header anyways.<p>But hypothetically, APC could make an ATX UPS today that would be compatible with most ATX motherboards and leverage most of their existing software and drivers to do so.
