In around fall 2006 having suffered a power supply failure I did a lot of research on desktop power supplies before purchasing a replacement. A company I came across was PC Power & Cooling. They had papers on their site discussing the importance of large capacitors, heat sinks, and a strong high amperage single 12V rail (at a time when power supply wattage was rapidly climbing but on dedicated rails). The said their power supplies were such high quality that they only needed a single 80mm fan to cool their power supply and were offering a 3 or 5 year warranty when 1 year was industry standard.
