Thanks, I'll look into that.
I'm sure you are right, as I know nothing at all about power supplies. But surely computers actually use DC, so couldn't my torch-battery device just supply the PC components directly?
You will either need many different batteries for the different voltages (1.2, 3.3, 5, 12, -12, -5) or a DC ATX power supply (not cheap and not very powerful until the 48V input variety)
Surely one 12v battery would do? It is only meant to last for 30 seconds or so, so wouldn't reducing the voltage be easy enough? I repeat that I don't know what I'm talking about ...
The PSU transforms incoming electricity to various voltages on multiple rails. You need more than just a 12V lead acid battery.
