x1 cards are limited to 0.5 A at +12 V (6 W) and 10 W combined.
x4 and wider cards are limited to 2.1 A at +12 V (25 W) and 25 W combined.
A full-sized x1 card may draw up to the 25 W limits after initialization and software configuration as a high-power device.
A full-sized x16 graphics card may draw up to 5.5 A at +12 V (66 W) and 75 W combined after initialization and software configuration as a high-power device.[22]: 38–39
