300watt inverter, 700va ups and a 90watt powersupply?
As a student I don't have heaps of money to get my CarPC up and running so I decided on this setup, I already have a 300watt inverter for the car I got as a gift and I have a spare 700va UPS.
My CarPC has a 90watt powersupply, and it only draws about 70watts, So if I had this setup...
Car Power ----> Inverter 300watt -----> UPS 700va ------> CarPC 90watt
Would it work? I want the UPS in there so that when the inverter looses power from me turning the ignition to off the UPS will shut down the CarPC safely :)
The only concern I have is the UPS overloading the inverter as it is a 700va UPS, but I think that the CarPC only drawing about 70 watts, the UPS should only draw around about the same wattage.
