PSU by build: GPU + CPU pairings

The power supply for a specific graphics card and processor together, rather than either on its own. Every figure is computed from vendor-published board power, and both parts of every pairing are verified against the manufacturer’s own specification.

This list is deliberately short. We add a pairing when people actually build it and the page has something specific to say — not by multiplying every card against every processor, which would produce hundreds of pages of near-identical arithmetic. Where two processors have identical peak power, we publish one page and name the equivalent chip on it.
