Why is the Industry Moving Power Supply Manufacturing to Vietnam in 2026?

Why Is Power Supply Manufacturing Shifting Away from Traditional Regions?

Power supply manufacturing is shifting away from traditional regions because OEMs are facing increasing pressure from tariffs, geopolitical risk, and supply chain instability. For years, many electronics manufacturers relied heavily on concentrated production hubs, but that model is becoming less viable as trade policies evolve and cost volatility increases.

As tariffs target specific countries and regions, OEMs are being forced to reconsider where their products are built. Power supplies, which depend on multi-tier component sourcing and complex assembly, are especially sensitive to these shifts. Manufacturing concentration now represents a risk rather than an efficiency advantage.

The move is not purely reactive. OEMs are proactively diversifying manufacturing to reduce dependency on any single region and to create more flexible, resilient supply chains that can adapt to future disruptions.
