This is news, though it doesn't seem like it at first glance. As the article points out, Zalman has been doing this for a while now.
We need more high quality, high peformance power supplies. As our systems become ever more sophisticated and require larger capacity power supplies and a power stream that adheres more closely to the necessary standards, the "toss in one of these" mentality by which many of us have been working is outmoded. Small variations in the power stream that your Pentium III would never have noticed will destabilize any of the current dual-core systems. For this reason alone, it is entirely within the scope of probability that the day of the serviceable yet inexpensive power supply is fast going away. We will have to pay a bit more - not a lot - to ensure the stability of our systems.
