God, you newbies, you have absolutely no idea how it works, do ya?
The startup and shutdown timers are the most important thing, and hardest to do, for in car use.
A few years ago, getting a DC-DC ATX psu with Startup and shutdown controllers was almost impossible.
You could get a DC-DC one after a while, but we still waited on the one with shutdown controller.
And when it did you were looking in excess of $250 when a simple ATX PSU could be picked up for $30.
Now you can pick up DC-DC supplies with Start/Shut that are more powerful and better quality for $90
It is because of the early innovators and adopters that prices have come down and quality has gone up.
The same will happen with this product.
Now quit ya b'tching.
