The power supply units (PSU) market size is projected to expand from USD 35.86 billion in 2025 and USD 38.03 billion in 2026 to USD 52.19 billion by 2031, registering a CAGR of 6.54% between 2026 to 2031.

Demand is shifting from high-volume commoditized bricks toward value-added topologies that meet hyperscale data-center density targets and electrification mandates. Tightened no-load efficiency limits under the European Ecodesign Directive and California's Title 20 are accelerating adoption of digital control loops and synchronous rectification. At the same time, Intel's ATX 3.0 specification has upended the gaming segment, forcing vendors to redesign transient-response circuitry for GPUs that exceed 600 W draw. Raw-material volatility in ferrite cores and silicon carbide wafers is widening the cost gap between vertically integrated incumbents and fab-less challengers.
Hyperscale operators announced more than USD 6 billion of new facilities during 2025, each requiring PSUs that deliver 96% efficiency at 50% load and hot-swap modularity to meet five-minute repair windows. Edge deployments compound demand because 5G base stations need compact units that survive -40 °C to +70 °C ambient ranges. Liquid-cooled racks drive interest in 54 V bus architectures that cut resistive losses, although pilots at Amazon Web Services and Meta remain in validation. Suppliers with digital telemetry and predictive maintenance in their racks report higher design-win rates as operators monetize uptime. Consequently, the power supply units market is tilting toward high-density, data-center-specific platforms that command premium margins.
The ATX 3.0 guide introduced the 12VHPWR connector with 200% transient tolerance, reshaping the enthusiast PC ecosystem. NVIDIA's RTX 50-series launch made compliance mandatory, and Corsair noted that ATX 3.0-ready units counted for over 70% of its Q4 2025 shipments. Workstation builders targeting AI rendering embrace dual-rail 12 V outputs that balance multi-GPU loads without breaching UL 62368-1 limits. OEMs willing to absorb redesign costs gain early-mover recognition among gamers and content creators. This refresh cycle bolsters average selling prices, lifting the power supply units market even as unit volumes stay flat.
Ferrite core prices surged 22% year-over-year in Q1 2025 because of supply disruptions at Asian producers. Silicon-carbide MOSFET average selling prices remain three to four times higher than silicon, with lead times extending beyond 26 weeks as of January 2026. Copper foil inflation, tied to EV battery demand, forces redesigns of printed-circuit-board trace widths to maintain bill-of-materials ceilings. Larger firms hedge through multi-year supply agreements, but smaller ODMs face margin compression that slows new-product introduction. Such volatility erodes profitability across the power supply units market, especially in mid-tier consumer segments where pass-through pricing is limited.
