A technician installs a new high-end gaming card into a computer but is not seeing any video. Which of the following power connectors did the technician MOST likely forget to install?

The correct answer is B. 6/8-pin Molex. High-end and gaming graphics cards require supplemental power beyond what the PCIe slot provides. They use 6-pin or 8-pin PCIe power connectors (sometimes called PCIe Molex connectors) that connect directly from the power supply to the GPU. If these connectors are not attached…

Explanation

High-end and gaming graphics cards require supplemental power beyond what the PCIe slot provides. They use 6-pin or 8-pin PCIe power connectors (sometimes called PCIe Molex connectors) that connect directly from the power supply to the GPU. If these connectors are not attached, the GPU will not function or display video even if it is properly seated. The 20-pin and 24-pin connectors power the motherboard, and the 4/8-pin 12V connector powers the CPU.
