When sourcing the Xbox Series X, you must verify the Custom SoC (System on a Chip) which features an 8-core AMD Zen 2 CPU and a 12 TFLOPS RDNA 2 GPU. Ensure the units are the standard 1TB NVMe SSD models. Crucially, identify the Regional Version (HK, US, EU, or Mainland China); while the hardware is largely identical, power cord types and software region-locking for local services vary. For international resale, Global/International versions are highly preferred to ensure full access to the Xbox Store and Game Pass without regional restrictions.
