Is the requirement for a specific wattage of PSU more or less down to graphics card? When selecting a PSU is the primary motivation to go for a higher wattage PSU based on the specific graphics card and/or number of graphics cards (SLI, crossfire)?

"In other words are all other
components in a computer relatively
negligible in their PSU requirements
compared with a modern graphics card?

no, they're not negligible, you can use Newegg's online PSU calculator. you will see how each component adds to the PSU requirements."
