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 PCI-E 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.
