Can a PSU be connected to a DC source ? Asking because.... http://images.electronicsinfoline.com/View/Photo/10001/Atx_power~0.gif" [Broken] ....i see the AC input, followed by capacitors and inductors (or are they transformers?), then the line is rectified. But we don't necessarily need AC to pass through a rectifier. DC should be used with no problem. Am i right ?
