A cable from this connector may be routed to a power connector on the given add-in card. Maximum power draw for each connector is 225W, but is also limited by available power provided by the power supply and the total power draw of the rest of the system. A power budget for the complete system should be performed to determine how much supplemental power is available to support any high power add-in cards. Table 25.
