Who knows how long it will be updated and accurate, but as of this posting it has most of the latest and greatest computer parts listed. This is a nice reference for anyone building new systems and selecting a PSU.
I love it. It is actually the most accurate I've come across, but in their own words, useless. From their page:
The recommended total Power Supply Wattage gives you a general idea on what to look for BUT it is NOT a crucial factor in power supply selection! Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage. Example: PSU you want to buy has 400W total wattage output but only has 16A on +12V rail. But your configuration might require 20A on +12V rail.
So when will someone come up with a power supply amperage calculator?
