12VHPWR 16-Pin Power Adapter Cable
The RTX 4080 utilizes four micro-sense pins (S1-S4) atop the 16-pin power connector to negotiate power delivery. If these pins are slightly displaced due to cable tension or poor terminal seating, the GPU's Power Management Integrated Circuit (PMIC) will not authorize the VRM to initiate the secondary rail, causing the motherboard to hang on the VGA initialization step.

VESA Certified DisplayPort 1.4a Cable
High-bandwidth DisplayPort connections require a rapid handshake of Extended Display Identification Data (EDID) during boot. If the cable is poor quality or fails to meet VESA timing standards, the GPU may fail to establish a link with the monitor fast enough for the UEFI POST, resulting in a 'No Display' status light even if the hardware is functionally sound.

GeForce RTX 4080 Graphics Card
If external power and cabling are verified, a persistent white VGA light indicates a failure of the GPU's BIOS/UEFI ROM chip or a hardware fault in the PCIe interface logic. In these instances, the card cannot present its Graphics Output Protocol (GOP) driver to the system BIOS, necessitating a replacement of the entire assembly.
