When building a new PC, the video card has a substantial influence on selecting the case and power supply. High-performance graphics cards can be quite large and may require specific dimensions, airflow features, and cooling solutions in a case to ensure optimal performance and temperature management. Additionally, power-hungry video cards also necessitate a power supply unit (PSU) with adequate wattage and suitable connectors to support them without compromising system stability. Another important aspect to consider is the motherboard disk type, as certain cases and power supplies need to accommodate different configurations for drives—whether traditional HDDs or modern SSDs. The motherboard's size (ATX, Micro ATX, or Mini ITX) will also determine the case's compatibility, ensuring that everything fits together nicely while avoiding any bottleneck in performance or functionality.
