Taiwan suppliers target OCP power, cooling, 1.6T integration

The competitive unit in AI infrastructure has shifted from single-chip performance to integrated thermal-electrical-optical system design. The 800VDC, liquid cooling, and 1.6T interconnect triad is the new moat. Technical cascade: 800VDC pushes rack density past 100kW, rendering air cooling obsolete and making liquid cooling a baseline requirement. The voltage step-up forces complete redesign of connectors and PSU topologies, while 1.6T optics accelerates CPO from R&D to volume production. These three vectors converge at the system level, systematically eroding the pricing power of component-level suppliers. Supply-chain risk: Power and connector manufacturing remains heavily concentrated in Taiwan, China and broader East Asia. Layered on US BIS export controls targeting advanced packaging and HBM, this creates a dual vulnerability. If 800VDC becomes the de facto standard, this supply chain becomes a new geopolitical chokepoint. Market dynamics: NVIDIA locks in system definition via NVLink and custom silicon; Broadcom bets on CPO for optical interconnect dominance; Huawei and Inspur seek standard-setting leverage within OCP. OCP's openness is, in substance, a contest over reference design ownership. 12-24 month outlook: 1.6T CPO enters hyperscaler production, 800VDC becomes mandatory for new AI datacenter builds, and liquid cooling penetration crosses 60%. Value migrates to the integration layer; component margins compress further.
