We have always relied on Enermax for high performance, well manufactured (and usually expensive) power supplies. Enermax quietly unveiled their newest "Coolergiant AX" power supplies, which have all the trimmings we would expect from Enermax; copper shielded components, SATA connectors, smart fans, etc. However, the newest and probably most interesting function is the addition of a separate 12V rail for the CPU.
Those who have some EE knowledge (or those who learned the importance of a good the hard way) know what havoc a dirty rail can play on the memory, motherboard and processor.

The idea of a separate 12V rail for the processor appeals to us. For some reason Enermax was very generous to the 3.3V and 5V rails, but at the same time they leave much peak headroom for the two separate 12V lines. If the Coolergiant AX performs well in the lab, it could be the definitive power supply for P4 overclockers. Also look forward to the Coolergiant AX in upcoming roundups.

A watt is the SI unit of power (energy or work per unit time), and thus contains time implicitly: 1 W = 1 J/s. Perhaps you meant heat flux (i.e., power per unit area, or 150 W/cm2 )?Chuckles - Sunday, April 4, 2004 - link
I know its relatively minor, but there is an error on page one."A solid block of copper sits on the CPU, and is then sinked by 6 heatpipes anchored onto the 7mm aluminum chassis. Without moving components, the case is able to sink 150W per second!"
A Watt is a Joule per second, a measure of energy per unit time (power). Thus the article should read "... 150W!"
