8 + 8 + 8 pin GPU

8 + 8 + 8 pin

— powered by three additional 8-pin connectors.

Recall that each 8-pin connector provides power up to 150 watts. Combined with 75W coming from the PCIe slot, three of these connectors allow you to supply more than 500W of power to the graphics card (more precisely, 150*3+75 = 525W). The need for such power is found only among the most powerful, performant and, as a result, high consumption graphics cards; accordingly, 3 eight-pin connectors are an almost unmistakable sign of such a card.
