Which two existing components must be compatible with the installation of a new upgraded CPU?

To successfully install a new upgraded CPU, it is essential that the motherboard and power supply are compatible with the new processor. The motherboard must support the specific CPU architecture, socket type, and chipset required by the new processor to ensure proper installation and functionality. Different CPUs have distinct requirements, and if the motherboard does not support the socket type of the new CPU, it will not be able to connect or operate.

Additionally, the power supply must be able to deliver adequate power for the new CPU. Upgraded CPUs may have different power requirements compared to older ones, potentially requiring a power supply capable of providing increased wattage or specific power connectors. If the power supply cannot meet the demands of the new processor, it could lead to instability or failure to boot.

In contrast, while RAM is important for overall system performance, its compatibility isn't directly related to the CPU installation itself, as long as the existing RAM is supported by the motherboard. Hard drives, graphics cards, monitors, network cards, and keyboards do not affect the CPU installation directly, though they play significant roles in the overall functioning of the computer system.
