Microsoft designs and engineers Xbox consoles in Redmond, Washington, but manufacturing is outsourced to contract partners globally. The primary assemblers have shifted across generations:
Key parts come from separate specialists: AMD (APU), Samsung/SK Hynix/Micron (GDDR6/NAND), Seagate (expansion cards), and various PCB/substrate vendors in Taiwan, Korea, and Japan.
Bottom line: An Xbox is a globally sourced product—designed in the USA, assembled primarily in Mexico and China by Flex and Foxconn.
