Are you sure it requires 750W or that it has a 750W PSU? If you need 20min at 750W, you're going to need a generator. If your computer actually only needs 20min while at mostly idle (~100W for gaming computers watching a video or doing Office software), cyberpower pure sine wave series CP-850 should be more than enough.
