A server with a number of graphics cards installed was recently upgraded with additional graphics cards. Once the server is started, the system powers off unexpectedly. Prior to the upgrade, the server was stable and exhibited no odd behavior. Which of the following is the MOST likely cause of the problem?

Question

Accepted Answer

B. The power supply cannot handle the additional power for the new cards. Graphics cards are among the most power-hungry components in a server. When additional cards are installed, the combined power draw may surpass the PSU's maximum output, triggering an automatic shutdown to protect the hardware. This directly explains why the server was stable before the upgrade and only fails afterward.

Answer

A. The card device drivers are out of date and need to be updated. Outdated device drivers cause software-level errors or device malfunction, not system-wide unexpected power-off events.

Answer

C. The operating system does not recognize the new cards. An OS failing to recognize new hardware produces unknown device errors or limited functionality, not a complete system power failure.

Answer

D. The cards are not compatible with the other server hardware. Hardware incompatibility typically manifests as boot errors or device faults rather than an abrupt power-off, and is less likely than a PSU capacity issue given the specific symptom.
