Inverters, DC, and AC, oh my!
Alrighty- oh- folks, here's the lowdown.
For reasons unknown, and somewhat illegal if put in the wrong context, I need my PC to draw under 150 watts of power (and, yes, this might be because I'm trying to have my 15 inch flat panel display flash random cuss words at others out of my rear window- but then, it might not). Anyway, My current power supply takes 115 V at 5A AC and outputs 200W DC, which, as my calculation go, is a skabillion watts of power; and the DC-AC inverter needs to be clipped to the battery for more than 150 Watts, so I ask thee; do I need to buy another low-end power supply as to avoid laying wire through my car, or would simply disconnecting all unnessecery devices to lower the power draw work?
Bear in mind, I'm not an electronics guru, and when I was 5, I stuck tweezers in a wall outlet and went to the hospital.
