The goal of this question is to only supply power to a computer long enough for it to stay up from a flash blackout. (no monitor) I am not talking about even enough power to allow for shutdown. At least 90% of the time the power goes down here is just from the flash blackout. This could happen 3 times with only 2 or 3 seconds down time. So what I am talking about is 10 seconds backup for a computer with say a 400w PS.
Anyone know what something like this would add to the cost of a computer? How small do you think the battery could be? Think it could be small enough to mount in a 5.25inch bay? Could it be built to just accept the connections from the PS and then furnish the connections to the mobo?
