Memory & Storage: Speed Tools
- DDR5‑6000+ RAM: Aim for 32 GB (2×16) high-speed kits a sweet spot for modern gaming.
- M.2 PCIe 4.0/5.0 NVMe SSDs: Opt for 2 TB+ Samsung, WD Black, or Sabrent units for fast game load times and workflow efficiency.
Power & Cooling Essentials
- PSU: High-end GPU like RTX 5090 demands ≥1000 W, Gold/Platinum rating, and multiple PCIe 8-pin connectors.
- Cooling:
- AIO / air coolers with high performance (e.g., Noctua, Corsair) are essential for X3D CPUs.
- Maintain positive airflow in the case for GPU thermals.
