Bear1985 Posted June 27, 2008 Author Share Posted June 27, 2008 Its less efficient as it has to convert 12v -> 240v then again 240v -> 12v - Each conversion requires power as they are far from 100% efficient. A computer only needs 12v so a proper car PSU will probably use quite a bit less power. When you say it drops to 8/9v do you mean just for a split second and then it goes back up to 14v? (To be honest the power cap does not actually do that much) I agree with both of these points and the other benefit of a proper car psu is the ability to start up and shut down the system with the ignition switch. I drop my car PC to hibernate automatically when the ignition turns off. Does your invertor get hot? If so there's proof of the power inefficiency! It's also a topic for debate whether or not you get benefit from using a capacitor - especially if you have a fairly chunky alternator/battery which I'd guess the zed does to crank the big V6. I will havw to check if the power invertor gets hot as Im not sure. Power when I start the car the PC turns on automatically. I set the BIOS so that when there is power the PC turns on automatically. When I stop the car I simply press the button behind the seat and the PC goes into hibernation. Not quite as efficient as a car PSU but it works well. Once its all up and running it will be firing on all cylinders and I'll love it! Haha Alas still no more driving for 5 weeks! Quote Link to comment Share on other sites More sharing options...
