After all, we're in for a surprise with the Gigabyte X48 motherboard. It's the first time I've heard of dynamic PWM, how it works and why it may be good for everyone.
The more phases a PWM has, the more it will dissipate energy doing nothing. Since it's distributed by more phases you have the advantage of cooler running components and a more stable voltage supply than a PWM with less phases. On top of that, electrical noise generated by inductors is usually greatly decreased also. But if you lose more energy doing nothing then you're not "saving the planet". Gigabyte's engineers came up with a solution for the problem, which is the ability to turn on and off as many phases as needed while the system is in idle or load, so this way we get the best of two worlds.
Don't take this as certain but Gigabyte is rumored to be introducing this technique motherboards that feature more than three-phase PWM and not just the 12-phase high-end motherboards.
