You are conflating things that might be outside your computer with things that are inside it.
Everything inside your computer (beyond the power supply) runs on DC.
With a DC supply, capable of generating 5 and 12 volts, you don't need anything else.
I'm not conflicting anything. I just described what happens within a switching power supply, as is used in a PC. With that box, you have AC coming in and DC coming out. The stages I showed were part of that process and nothing else. As I tried to explain, by using high voltage DC, you can bypass the DC > AC in the UPS and also the AC > high voltage DC in the power supply, which in turn provides a bit better efficiency than running AC between the UPS and computer power supply. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
