Re: Specs
Have the batteries located where the PSU is currently located.
You can't use all of the PSU's space for batteries, as you still have to convert the battery voltage to the other voltages used in the system for which you need about one-third of the space a standard PSU takes. For low-power systems (Mini-ITX) you can use PicoPSUs of the appropriate rating which run off 12..18VDC, so easy enough to run off a battery with a charger attached. But for larger systems, especially with beefier video cards, those won't cut it
I'm not sure if for those larger systems the reduction in conversion losses is worth it regarding the various stuff you need to do it this way.
