    How much unstable? Asking without perspective (ie numbers) means everything or nothing can be recommended.

    For example, normal voltage for any computer is even when incandescent bulbs dim to 40% intensity? How often is your voltage dropping that low?

    Voltage regulation is what every supply for all electronics must do. For example, normal voltage for a laptop is anywhere from 85 volts to 265 volts. Demonstrating but again why numbers (perspective) must always be included in any technical recommendation.

    An UPS IS a voltage regulator. You don't need both.
