Which connector type is found in the upper left corner of the motherboard for CPU power?

The 8-pin connector is typically used for supplying power to the CPU on a motherboard, which is critical for the stable operation of the processor. This connector allows for more power delivery compared to the older 4-pin connector, accommodating modern CPUs that require higher wattage, especially during intensive tasks or overclocking scenarios.

The placement in the upper left corner of the motherboard is a standard design to provide easy access to power the CPU directly from the power supply. This design ensures that the motherboard can efficiently distribute power to the CPU without significant voltage drops.

In comparison, the 4-pin connector is more common in older motherboards and may not supply enough power for modern CPUs. The 20-pin connector is used for the main power connection to the motherboard and does not specifically serve the CPU, while a 12-pin connector is not standard for CPU power in most consumer desktops. The 8-pin connector has become the modern standard to meet the increasing power requirements of contemporary processors.
