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.
