Vortex Sound Research

I'm trying to get a better understanding of my options for DC powering items in my mobile rack rig to remove wall warts. Most items are 12V 3 to 5A.

There's options for musicians but I don't think they supply the needed amps that I would need. Something like this would be ideal just with higher amps.

Maybe a CPU power supply and Molex to DC barrel connectors?
