In 20/24-pin configurations, the Mini-Fit Jr. connector may be used on ATX motherboards as the main power connector. The same style of connector, in single or paired 4-, 6-, or 8-pin configurations, may be used for additional CPU power and graphics card power. Power delivery to these devices has increased in successive generations of PC components, as their higher signal sophistication and speed requirements have raised their electrical demands. The Mini-Fit Jr. can also be found in other consumer and industrial electric devices, such as major appliances, with high circuit density and high current requirements.
