Which of the following expansion cards would MOST likely have the requirements of utilizing a direct auxiliary 6-pin power plug to operate properly?

The correct answer is B. PCI Express video card. A PCIe x16 slot supplies a maximum of 75W of power. High-performance graphics cards (GPUs) far exceed this, often requiring 150W to 300W or more. To supply the additional power, video cards include one or more auxiliary power connectors - the 6-pin PCIe power connector provides…

Explanation

A PCIe x16 slot supplies a maximum of 75W of power. High-performance graphics cards (GPUs) far exceed this, often requiring 150W to 300W or more. To supply the additional power, video cards include one or more auxiliary power connectors - the 6-pin PCIe power connector provides an additional 75W, and an 8-pin provides 150W. No other common expansion card type (RAID, FireWire, or LAN) draws enough power to require auxiliary connectors - they comfortably operate within the slot's 25–75W budget. Therefore, a PCI Express video card (B) is by far the most likely card to require a 6-pin auxiliary power plug.
