The Overlooked AI GPU Power Supply Chain

Based on industry checks, the author notes that Monolithic Power Systems currently captures roughly 70% of the voltage regulator slots on NVIDIA's latest generation of GPUs.
He emphasizes that such companies occupy a critical chokepoint between grid power and the GPU silicon. While modern AI GPUs operate at voltages below 1V, they draw over 1kW of power, requiring the delivery of thousands of amps while maintaining ultra-stable voltage regulation to prevent chip failure.
He provides another example: In Analog Devices' earnings, Q2 data center revenue surged by over 90% year-over-year, now accounting for more than three-quarters of its Communications segment. As AI rack power scaling evolves from hundreds of kW to the MW range, the content value of power management and analog components continues to rise.
The conclusion: While the market may have fully priced in GPU scarcity, it has yet to completely account for the analog and power infrastructure required to keep these GPUs running.
