Probably not, most power supplies go straight to a bridge rectifier - you can supply a bridge rectifier with DC and it will output DC just the same. But it’s possible to design a power supply that does it differently, in which case the designer - presumably also the user - would likely know what it needed.
If it internally runs on 5v stepped down, for example, you could just feed it from a handful of proto-potatoes and bypass the whole 110v AC section
Oh god, we’re overthinking a ‘shitty’ larson-esque comic now
