I told the guy to run a power calcualtor. You don't do anyone any good by making blanket statements like, You can power everything you want with a PS, which is essentially what you have done. And, what the hell is a "TYPICAL" system? Again, you are just throwing lanket statements out there, which are not 100 percent correct.

This place is for carputers. MOST of the applications involve DC-DC PS's, and not AC-DC, so again, ASSUMING that it is an AC-DC doesn't help the OP.

Next, just because YOUR PARTICULAR system runs fine, someone with a different system may not run fine. Your system specs are obviously under the specs of the Pico PSU you are using. Why do you assume that the OP, or anyone else for that matter, will be so lucky. There are MANY instances of people overloading their DC-DC PS's.

Additionally, the PICO doesn;t regulate the 12 volt output. So, you must be powering this with some sort of 12 volt regulator. That ight be able to supply more then enough current on the 12 volt rail for your items. THat 120 watt rating is therefore a COMPLETE FALLACY, and in essence, might be much higher if your 12 volt supply is providing more then 8 or so amps.

You are NOT using that in a car, are you. That is a VERY POOR choice, with out any additional voltage regulation on the 12 volt side.
