Lets call that wattage amount the card's TDP, for the sake of simplicity.

However, they likely 'expect' a card with this connector configuration to draw something like 175W. The max 'rated' wattage draw from each of these three connections is 75W, and you have 3, so the absolute max wattage draw that AMD is going to 'allow' your card to draw is 225W. Let's say you have 2 x 6 -pin connectors on your card + the power from the motherboard. Your card has some amount of 'juice' it's expected to run at, at a maximum. It's something more akin to 'wattage control'.
