Need to power 3 more things.

I already have a p1900 for computer, monitor and hub . I guess I need another regulator. I was looking at the p2140 but seems like more than I need (feature wise).
I need to power a rear 12v camera, 12v 3a TV tuner and a 12V tv antenna. All items are in trunk.
I want to only run one power cable to the trunk for all 3 items. I dont want a timer, i just want it to turn on when car is started or car radio is on (first key turn before starting) and off when main car power is off without having a trigger line or usb(p2140).

By car antenna, I'm assuming you mean a power antenna.

I don't know your setup specs, but it's very possible that you can tap into the 12v from the computer PSU for the camera and the tuner.
I would use a relay to trigger the power antenna, though. I'm sure the motor is doing to draw more than the P1900 can supply.

And the P2140 has no USB requirement. The USB is only for monitoring the PSU, and is not required.
If your P1900 is not sufficient for all you want, then it would be a good option, although I'd still use a relay to trigger the power antenna.
