As long as you find a conditioner or surge protector that can provide a grounded power sources with enough amperage to cover both the mixer and your computer you should be fine. If you are really nervous about the power situation in a particular room or venue, I would suggest that you find a good power conditioner with built-in voltage regulation to ensure a consistent and clean 120v of power. On a personal note, Furman is my preferred brand, but not at all a direct recommendation of PreSonus.
