In the beginning of the article, the fundamentals of Switching Power Conversion will be explained and a brief description of the various stages that compose a PSU will be made. In addition, we will make a quick reference to some switching regulator topologies used currently. A few pages dedicated to PSU protections are following and next we take a look at ATX, EPS and 80 PLUS specifications. Finally, in Appendix A we make a quick reference to the most significant electronic components currently used not only in PSU manufacturing but also in every modern electronics device. So you will learn the basic concepts of inductors, capacitors, resistors, transistors and diodes, in order to get familiar with them and understand better some concepts discussed in this article.

Quite an interesting read for anyone who is wanting to know more about PSUs

:notontopiI don't see the power supply as the heart of the system. I see it as the mouth since it takes in electricity to distribute it to the other parts. I see the power cables as the digestive system. I see the processor as the brain, the motherboard as the body (connects everything together), the RAM as the forgetful part of the brain in memory, the hard drives as the less forgetful part of the brain in memory, the graphics cards as the eyes, and the audio as your larynx (voice box). On topic: Nice read.

Edit-to me, this isn't really news.

This ain't news mate, but good read

Perhaps get it moved to the PSU section

Off-Topic: PSU makes more sense as the heart, as it doesn't create electricity/blood but supplies it through the cables/veins to the other parts.

On-Topic: This seems like something that should be stickied in the psu section

i think of the PSU as a dumb part that should just work and be forgotten about.

Yeah yeah, make fun of me for not posting this.

Sorry, but I'm on a bit of a Stargate: SG-1 binge. Too busy watching Baal and Anubis get their butts kicked to follow the computer news.

This was done by crmarris, a Greek reviewer I know through JonnyGURU.com/forums. He does PSU reviews for a site called thelab.gr. He's at my level of knowledge or a bit above, with the added bonus of having a PSU testing setup.

This is a good read. Only complaint really is that he basically ripped the "PSU Topology" section straight from Wikipedia (prettied up a bit of course). There's some topologies on there that aren't seen in ATX PSUs, some overgeneralizations, the diagrams vary in quality, and I would not have organized it that way. Plus "LLC Resonant Converter" isn't a standalone topology used in ATX PSUs--LLC resonance is implemented within existing topologies, like half bridge and full bridge.

But the rest of the article is good stuff.

Good read. I'd like to see more voltage/current waveforms though, especial in the switching topology section.
