Power Integrations' GaN technology is locked into Nvidia's next-gen AI supply chain through its auxiliary power-supply designs for Nvidia's Kyber 800V DC liquid-cooled racks, where its high-voltage GaN chips deliver high efficiency in a tiny footprint. Its 1250V and 1700V devices from the Odyssey deal are gaining traction in industrial drives, 800V EVs and solar inverters. With its consumer business recovering from a cyclical bottom, earnings recovery plus an AI re-rating set up a double play. … Show more

Power Integrations should be very successful over the next one to five years because it makes the only GaN switches needed for NVIDIA's new rack architecture. x.com  x.com 

A rising value of compute per watt should benefit AI cloud, chip, connectivity and power suppliers. Elon Musk says that value will rise over time. Nebius has Microsoft and Meta deals; Marvell benefits from custom silicon demand; Credo connects GPUs; Vistra has long-term nuclear supply deals with Amazon and Meta; Nokia's Nvidia partnership could help it capture data-center networking growth. x.com  x.com 

Denser AI accelerators raise the value of efficient power delivery near processors, potentially making Navitas one of the most hidden AI winners in Nvidia's architecture. Its 24 kW board targets single-stage 800V-to-12V conversion at about 97% efficiency in Nvidia's 400 mm by 60 mm format. An 800V-to-6V design developed with Nvidia and Claros offer other paths into the power stack. This is a showcase, not a production order; shipment volumes, revenue and competition remain uncertain. x.com 

Nvidia's official 800 VDC architecture partners stand to benefit as AI racks move to high-voltage DC power. They span GaN and SiC chipmakers Navitas, STMicroelectronics, onsemi and Infineon; conversion and analog suppliers Alpha & Omega, Power Integrations, Texas Instruments, Analog Devices and Monolithic Power, whose VRM chips are already inside Nvidia GPUs; and rack, building and grid power players Flex, Vertiv, GE Vernova, ABB, Eaton, Schneider Electric and Siemens. x.com 

Vertiv benefits from every AI data-center buildout because rising rack power makes power management, UPS, distribution and liquid cooling, its core businesses, ever more critical. Wall Street keeps raising estimates, with a consensus target near $375 and revenue seen rising from about $10.8B to over $21B by 2028. NVIDIA's shift to 800V DC power, which Vertiv already supports, and rising liquid cooling add growth. A months-long wedge could break out on Aug 5 earnings if orders and guidance beat. … Show more

Vertiv's power and cooling gear is benefiting from the AI data-center build-out. Q3 net sales rose 61%, operating profit 90% and net income 92%. There is no more direct picks-and-shovels bet on AI infrastructure than Vertiv. Grade: A. x.com 

AI power-semiconductor suppliers stand to make generational money as AI racks outgrow data-center wiring. NVIDIA's 2027 rack pulls 600 kW, while wiring built before 2025 was designed for 40 kW, so 800V DC power sidecars are being bolted beside existing racks. Those need silicon carbide and gallium nitride chips, made at volume by only a handful of companies whose stocks fell 40-60% as EV demand slowed. Amazon, Microsoft, Google and Meta are now new customers that are not bargaining on price. … Show more

Vertiv and Quanta Services get paid whether or not Nvidia's Rubin Ultra ships, because every rack upgrade is a power-infrastructure contract. As @KawzInvests explains, Rubin Ultra's 600-kilowatt racks cannot run on old wiring, so Nvidia moves power conversion to an 800V DC sidecar rack, raising semiconductor content per power unit from about $95 to $880. The rewiring itself is the trade. x.com 

Vertiv's surging orders and Q3 growth show AI infrastructure demand exceeding expectations. Per WallStEngine, revenue rose 61% to $4.3B, adjusted EPS rose 78% to $2.21, organic orders grew more than 100%, and FY26 guidance was raised above estimates. Vertiv is delivering into accelerating demand for its power and cooling equipment. x.com  x.com
