OCZ acquired PC Power & Cooling in 2007. However, PC Power & Cooling never made any power supplies. PC Power & Cooling is not at manufacturer. Both PC Power & Cooling and OCZ power supplies are made by other companies. The PCP&C Silencer series was manufacturered by Seasonic. That's what made them so great. The other PCP&C series are made by another company. OCZ power supplies are made by half a dozen manufacturers. Only a small number of OCZ power supplies can be considered high quality.
Most power supplies advertised as having mutiple +12 volt rails do not have true mutiple rails. Instead mutiple rails can be thought of as "virtual rails". It was an advertising gimmick. There was a big stink about it a few years ago. There are a few high end, high wattage power supplies that really do have multiple rails. They were designed for use with high end systems that have 3 or 4 power hungry video cards installed.
All modular and hybrid modular power supplies do not lose any power. You're probably referring to resistance which is so small as to be completely insignificant for the typical gamer and enthusiast.
jaquarskx - I've been using Corsair exclusively for the past 5 years or so. For my new personal pc I sprung for a Seasonic X-650 Gold Certified psu. Brand new energy efficient design. I've got my old Corsair HX620 in my emergency backup pc.
delluser1 - Yeah, I know and I had just posted about it in another thread but I couldn't remember the manufacturer's name and I was too lazy to look it up.
In the meantime, I am a very happy camper. I installed Windows 7 Pro 64 in my new personal Intel Core i7 860 pc last weekend. I just finished installing and testing the last of my mainstream applications and updates. It's a bloody miracle! Everything works flawlessly. No BSOD! No freezing, stuttering, or strange things happened. I can't believe there were no compatibility issues. Absolutely amazing!
