Ah, manufacturers do sell this stuff at least a few years back. It
came with a battery pack that was installed into the 5.25" drive bay.
But as this type never made it into mainstream awareness, likely due
to the low cost of a basic UPS nowadays, it just didn't make sense
when such a PSU cost almost the same as a normal PSU + UPS. And the
UPS had a longer run time as well as being able to support a few other
accessories at the same time, and acts as a shield by sitting between
any power surge and your PSU, as opposed to the PSU + battery.
