    I allready told you the numbers don't jive. I even provided screenshots of the car cranking and proof that it only works up to a 15 amp load. That is only 180 watts peak. So, I obviously can't do that.

    The PW200 is not a 200 watt power supply. It is a cable with a 80 watt power supply for the +5 and +3. They do nothing on the 12 volts. The 18 gauge wire that it comes with, there's no way you'll even get 200 watts through it. That is marketing false advertising.

    ah i am beginning to understand now... guess i've been had, or i dont read into things enough... probably the latter

    sounds like i've wasted enough money on all the wrong stuff, perhaps i should roll with that key power psu and be done with this silliness

    Given the length of the wire, it should still work I would have thought - the wires might just get a bit warm. Luckily my setup is only driving about 84W peak so I don't have to find out the hard way.

    Mines still going strong. Trying to decide whether to buy zootjeff's shutdown controller or roll my own - or live without one (I'll definitely be doing this for a bit ). I think I've decided against getting one of his new regulators since I don't actually need one.

    Just trying to protect my investment. I've put a lot of time and money into it. And I think I've come up with a really great product.

    You sure have - the best of luck selling it. I think it'll be a real hit. I'm hoping so - I'm going to wait until it drops due to volume so I can pick it up cheap.

    I totally understand, I am just teasing.

    He could add a $10 7.2Ah sealed lead acid battery as a tank circuit. That's how I'm surviving crank with my linear 12V DC regulator circuit. I finally have it all hooked up in the car and the PC survives multiple cranks just fine . That would be a cheap extension to your circuit. Of course - I'm only drawing 7A and the voltage starts to drop pretty rapidly so I'm not sure what it would do with a higher current. It might survive crank but it probably wouldn't survive long after the car is turned off (in my case that disconnects the ACC line I'm using for power when the car is running) even if the PC was connected straight to the battery.
