In this build I walk you through the exact kind of PC I recommend for a modern golf simulator—because sims have gotten to the point where 4K graphics and high refresh rates can absolutely smoke a “standard computer.” The whole goal here is simple: build a rig that runs your sim software smoothly without bottlenecking the GPU, so your projector and graphics settings aren’t being held back by a weak CPU, slow RAM, or a sketchy power supply. I break it down step-by-step with a parts list that’s geared for a clean, reliable sim-room install: a solid Z790 board, a current-gen Intel i7, fast DDR5, a properly-sized PSU, and the cooling/fans to keep it stable when you’re running long sessions. I also included budget-friendly swaps (like an i5 option and alternate fans/PSU) if you want to save money without building something that you’ll regret upgrading a month later. If you’re stuck on compatibility, airflow, or what to prioritize for your specific projector/software, I’m always happy to help through pixelgolfco.com.
