Musashi Seimitsu is turning from a struggling, 90-year-old auto parts maker into a key AI data center supplier, which nobody is pricing in. It is one of few hybrid supercapacitor makers, pairing battery-like energy density with capacitor-like response. As AI moves to 800V power, only supercapacitors react fast enough to GPU load spikes, likely making them standard in every rack. Partner Flex is launching a storage system on its cells, and output is scaling from 200,000 to 6.5 million cells. … Show more

Musashi Seimitsu's hybrid supercapacitors look more necessary as Nvidia's Vera Rubin NVL72 racks arrive faster than expected. Dell delivered the first rack to CoreWeave on May 31, 2026, while the market had modeled Rubin as a late-2026 or early-2027 story. When the rack's 72 unified GPUs jump from idle to full inference load, the power surge hits the local grid like a shockwave, so data centers must deploy energy buffers to keep voltage sags from shutting down clusters. x.com 

Musashi Seimitsu is a higher-torque play on the AI power and 800V theme than MLCC makers like Murata and Taiyo Yuden. Its supercapacitors smooth AI workload power spikes, a role that grows as architectures move to 800V; Skeleton's product suits peak shaving and is more complementary than competitive. The supercapacitor market could top $15B within years at likely 20%-30% operating margins versus 5% in the base business, which could lift operating profit over 10x. Target: a 2x in 12 months. x.com  … Show more

Handling giant voltage and power swings is a big and arguably underappreciated opportunity over the next two to three years for battery storage and supercapacitor makers. Musashi Seimitsu and VinaTech are the preferred ways to play supercapacitor demand. x.com  x.com 

Meta's unmet AI demand pays its bottleneck suppliers. Super Micro's $19.5B quarterly outlook and under 8x forward earnings point to a double. CoreWeave's Meta deals total $35.2B; it should easily top $100. Builders say nearly all new sites use Dell or Super Micro; Dell could easily double. Micron's demand is off the charts at 5x forward earnings. Sources say Vertiv's gear is sold out for 2-3 years. VivoPower has 2GW+ potential in 5-7 years. Digi Power X has a $1.1B Cerebras deal. x.com  x.com  … Show more

Inference's move toward edge devices and dense, memory-hungry racks should drive demand for specialized chips, links, power delivery and cooling. McKinsey projects inference at 60% of AI computing demand by 2030. Ambarella makes on-device AI chips; Astera Labs links GPUs, memory and networks; Credo supplies short copper connections; Rambus earns from memory interfaces; Navitas reduces power waste; Modine cools dense racks; and Super Micro builds inference-specific server racks at volume. x.com  … Show more

G2AIStack's reported component yield and capacity bottlenecks make NVIDIA's Rubin shipment outlook look dire. It says Rubin system expectations were cut from roughly 10,000 to around 5,000, citing GPUs, orthogonal backplanes and power systems; its ODM checks indicate shipments are falling short. x.com 

Super Micro's work with SpaceXAI could be large: per Reuters via @wallstengine, it is moving full speed ahead on a gigawatt-scale AI data center with Nvidia GB300 systems, and its CEO teased a surprise Christmas gift. Elon Musk says another 220k GB300 come online next week, 220k in November and possibly 220k more by late December, roughly 660K GPUs connected by year-end, likely the gift the CEO alluded to. 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 

QuantumScape's solid-state batteries are positioned for high-density backup battery units in NVIDIA's 800 VDC power racks, which ship in the second half of 2026. Jensen Huang said the roadmap remains intact, with Navitas's GaN and SiC chips directly in the power conversion path. The power side of the AI factory trade just got another green light. x.com
