Thailand rides the 800VDC AI wave

Industry Overview

AI infrastructure enters its next upgrade cycle 14 July 2026

The AI buildout is moving beyond chips. As systems become larger and rack power rises Equity

from tens of kilowatts toward 600kW and eventually 1MW-class systems, the ASEAN | Thailand

bottlenecks are shifting to the infrastructure around the compute. Power delivery, Electronics

longer distances. Together, these changes expand the opportunity beyond GPUs into

analog ICs, power semiconductors, power racks, cooling, facility infrastructure and

photonics. AI: Artificial Intelligence

AC: Alternating Current

Benefits begin before full 800VDC adoption DC: Direct Current

Data centers are expected to upgrade gradually, since replacing everything at once AC/DC: Alternating Current to Direct

would be too costly and disruptive. They start with the most urgent step, improving Current

power equipment around AI racks so these can handle more electricity, then use 800VDC PSU: Power Supply Unit
