Comprehensive New Guide to Understanding PSUs

Power supply units (PSUs) are perhaps the least understood components when buying or building a PC. Very often, buyers don't look beyond the output power rating, and connectors provided. Slightly more discerning buyers look for efficiency rating, but that's about it.

Very interesting article. I wish there was an article that was as in-depth as this one that focused on what all the specs on PSU's mean and what is good/bad. THis article was excellent at outlining all the components within a PSU.

I was reading on Hardware Secrets about how to judge a PSU well when I was researching on whether to buy a HX750, which I now intend to buy.
Will be sure to check this article out nicely too to ground myself better.

Ceramic caps can show very high input oscillations which are greatly decreased by putting an electrolytic capacitor in parallel. Also electrolytic caps are cheap and if they are made by a good manufacturer (Nippon, Rubycon etc.) their reliability is very high.
