A suggestion for YOU IS ,
Purchase a wide voltage PICO PSU and an Optima car battery to supply it with,
so you/we don't have to worry more
and its sounds good

Just got this from Larry at HDPlex:

"Hi

I looked at his example and don't understand how PC power management chip on his motherboard can communicate with his PSU and function as it should during power on process. Without the control circuit from PSU to tell power management chip on the motherbord that PS ON is successful, the PC will just think it as a failed start and shut down again.

The PS-ON line needs to be at 5V when PC is off and will be lowered to 0V when Power ON is pushed.

All 12v 5V 3.3V needs to rise within 500ms of time.

So I think it is not possible without additional control circuit. In fact, the reality is more complex than time sequence and control.

You also need MSM chip to help the timing for certain motherboards..."

I was thinking of the HDPlex 200W with 4 outputs, but Larry said it is not possible to do what you have done with only the 3.3/5/12v?

So I'm hoping you can throw some light on his email response (above) please?

Cheers!
