Power button on the boardiA power or start button on the board itself, for use outside a case. A button with another label counts when the maker says it can turn the PC on, such as GIGABYTE's quick button labelled RESET. A button on the rear I/O panel counts. A button on a module that ships fitted to the board, such as MSI's EZ BRIDGE, counts.
