The global Server Power Supply Chips market size is predicted to grow from US$ 319 million in 2025 to US$ 794 million in 2032; it is expected to grow at a CAGR of 13.5% from 2026 to 2032.

In 2025, global Server Power Supply Chips capacity 170 million Pcs, sales reached approximately 163 million Pcs, with an average market price of around 2 USD/Pcs, industrial gross margin 51%.

Server Power Supply Chips have evolved from background components into strategic enablers for modern server and AI infrastructure. The competitive landscape is led by global IDMs such as Infineon, Texas Instruments, Renesas, onsemi and ST, which offer complete portfolios from PFC/LLC controllers to digital multiphase controllers and power stages, often paired with their own MOSFET, SiC and GaN devices. A second group consists of mixed-signal and power-management specialists like ADI, Microchip and others with strong positions in digital VR controllers and PMBus power-management ICs, while regional players in China and Taiwan focus on server VR controllers, DrMOS and PMICs closely tied to PSU ODMs. As a result, the Server Power Supply Chips market shows a layered structure, with a handful of global vendors owning the high end and regional firms addressing specific sockets and local ecosystems.

On the technology side, Server Power Supply Chips are driven by requirements for higher current, higher efficiency and deeper programmability. Front-end AC-DC stages use digital PFC and LLC controllers in combination with SiC and GaN devices to achieve 3?12 kW PSUs with peak efficiencies approaching 97?98% and full compliance with ORV3-class rack specifications. Board-level power delivery relies on VR13/VR14-compliant digital multiphase controllers and power stages that support up to 16 phases and hundreds of amps for CPU, GPU and AI accelerators, with interfaces such as Intel SVID, AMD SVI, NVIDIA PWMVID and PMBus for telemetry and control. In this context, Server Power Supply Chips are increasingly viewed as firmware-tunable, networked power resources rather than fixed-function analog blocks.

From an application and value-chain perspective, Server Power Supply Chips span the full path from rack-level AC-DC supplies to on-board VRs. Upstream, device and IP suppliers provide control architectures, power transistors and advanced packaging; midstream, IDMs and fabless vendors integrate these into Server Power Supply Chips; downstream, PSU ODMs, server OEMs and cloud or enterprise data centers embed them into complete systems. AI servers and high-density racks are the primary growth engines: multi-kilowatt PSU reference designs increasingly use GaN/SiC-based power stages controlled by digital power ICs, while next-generation CPU/GPU and HBM platforms push VR controllers to deliver faster transient response, finer telemetry and tighter integration with system management. Typical engagement models revolve around complete reference designs and BOMs, which gives Server Power Supply Chips substantial stickiness once designed in.

A recent move that illustrates the strategic direction of the Server Power Supply Chips market is Renesas? 2024 acquisition of GaN specialist Transphorm. By bringing GaN device technology and manufacturing in-house, Renesas immediately expanded its WBG-based power portfolio and released new GaN-centric reference designs targeting data center and server power, effectively combining its existing controllers and PMICs with advanced GaN switches for front-end and intermediate-bus stages. This type of transaction allows a traditional MCU/PMIC vendor to offer tightly coupled control-and-device solutions for Server Power Supply Chips, particularly in AI server and high-density rack applications where GaN and SiC adoption is accelerating.

Looking ahead, three structural trends are likely to shape the Server Power Supply Chips landscape. First, the shift toward 48 V racks and high-voltage DC ?grid-to-rack? architectures will pull power-control silicon closer to facility-level energy management, making rack and board controllers key actors in grid interaction and energy orchestration. Second, the volume ramp of SiC and GaN will drive new generations of controllers and drivers capable of higher switching frequencies, higher power density and improved EMI behavior, turning Server Power Supply Chips into the main gateway through which WBG benefits are realized in AI and cloud data centers. Third, the continued move toward digital and software-defined power?more telemetry, in-field reconfiguration, and data-driven fleet management?will position Server Power Supply Chips as levers for managing peak power, optimizing energy efficiency and meeting carbon targets at the system and data-center level, rather than just as local regulators on a motherboard.
