WattWise Tools
WattWise Tools is a free site for planning a PC's power use. It estimates the wattage a build needs, with reference pages for GPU and CPU power, an electricity cost estimate, a comparison of what an 80 PLUS efficiency upgrade pays back, and a UPS runtime estimate. The figures are planning aids. Manufacturer specifications stay the source of truth for a part.
