Optimize airflow with front intakes and top/rear exhaust, keep cables clear, and align fans to feed the GPU. Maintain slight positive pressure and use dust filters to sustain cooling performance.

Match your GPU’s wattage plus a 30% buffer, pick 80 Plus efficiency, and ensure adequate PCIe 8-pin/12VHPWR connectors. Favor quality rails, protections, and reputable reviews.

Balance CPU and GPU to match resolution and refresh rate-pair midrange GPUs with 6-8 cores, and flagship GPUs with 8-16 cores to minimize bottlenecks and smooth frametimes.

PCIe 5.0 doubles bandwidth, but most games rarely saturate PCIe 4.0. Expect similar FPS; gains mainly appear with top GPUs at 1080p or ultra-fast NVMe streaming.

Upgrade your GPU when games dip below 60 fps, VRAM is maxed, or new features (RT, DLSS/FSR) matter. Buy after price drops post-launch and when your PSU/case can support it.
