I cant see any power regulator switch and a 110V cable came with it so i'm guessing it works only on 110V?
PSUs with Active PFC usually have hard-wired line input and boost whatever they get to 300-400VDC for the primary storage cap(s) instead of using the error-prone voltage-doubler switch. Some passive/no-PFC PSUs are hard-wired with/without voltage-doubling circuitry with their primary-side designed to work over a wider primary storage voltage range.
In general, if there is no switch, the PSU has universal input range. When in doubt, check the label or manual.
