Indeed, many (though not all) manufacturers who are 80+ certified are listed at http://www.80plus.org/ . > Of course, many situations can find a few hundred dollars in labor and > downtime savings to justify a quality, efficient PSU. > > Unfortunately, I haven't seen any of the pre-built system vendors > mention the efficiency of their power supplies.

Yes, I haven't seen any numbers on those either, it would be interesting to find some information on the PSU's that the tier-1's include in their builds. I like to think that they are as efficient as they are reliable (I have found the PSUs in my Dell and HP servers to be 100% reliable so far....) but I find it more likely that they are not. As far as my own builds go, I've long been a fan of PC Power and Cooling. They were making high-end power supplies before it was cool to make high-end power supplies, and they have several 80+ models.. The Tech Report is pretty serious about power supply testing. They built a device they call The Beast for load testing PSUs, and they do PSU roundups regularly. The most recent one seems to be this: http://techreport.com/articles.x/16073 Anand Tech seems to have reasonable testing methodology and they do PSU reviews often as well. -QH- _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
