Of all the components that are in a PC, power supplies have probably been the most ignored. But from Extreme Edition CPUs to SLI graphics, the power requirements of enthusiast systems in particular have recently skyrocketed. We cornered Doug Dodson, the president and founder of PC Power & Cooling, the only American power supply manufacturer and arguably the finest maker in the world, to explain some of the inside tricks of his trade and what PSU buyers should really know before buying.

An Interview With Doug Dodson, President & Founder Of PC Power & Cooling
CPU: Modular power supplies seem to be gaining a lot of traction in the market, but PCP&C doesn?t make any modular designs. Why?
##this is one excerpt from the whole article##
Dodson: Yeah, it?s real popular, but the industry hasn?t done anything to educate people about modular plugs. The pins that are used in the modular plugs have a very low capacity to pass current. You?re losing power through those pins. It?s electrical resistance between the male and the female part of the pin, to the extent that the voltage drop in just the pins is equivalent to about two feet of wire. The effect is that modular power supplies, everything else being equal, are capable of about 10% less power than power supplies without modular plugs. And that?s under ideal conditions. In real life it gets worse because the pins loosen, corrode, and burn. Over time the resistance builds up. A year down the road, a guy could be running his system and all of a sudden it stops working reliably, and he has no way of knowing that the reason is because the pin inside that modular plug has become corroded or burned. This technique has been out for about six months, but people are going to find that the reliability is a massive failure point. Also, especially given the way people pull their harnesses around and tie them down, it creates a lot of stress on those pins. So instead of the pins having full 100% contact surface to surface, in most cases those pins are only touching maybe 10% or 30% of their surface area. What?s rated for 5A going through those pins, in reality if the pins aren?t making good contact, your rating?s down to maybe 3A, and with that much constriction, those pins just heat up, and it gets worse. For real pros in the industry, no way would they specify that kind of arrangement. This is a consumer-oriented gimmick.
Interesting article-----Yes this is old news! That still holds true todaY!!
