Data center electricity demand is on track to more than double — from 460 terawatt-hours in 2022, about 2% of global electricity, to roughly 1,000 TWh by 2026, around 8%. AI is the engine behind that curve, and a surprising share of the loss happens before power even reaches the processor: in the routing of the power delivery network (PDN) itself. ASE's powerSiP™ platform targets that loss directly, cutting routing power loss in half and increasing current density by 50% by moving voltage regulation from beside the processor to directly beneath it.
The Loss Is in the Path
In a conventional side-by-side configuration, the voltage regulator module (VRM) sits next to the system-on-chip (SoC), and current travels a relatively long lateral path through the board and package to reach the die. That path dissipates roughly 12% of the routing power as loss. ASE's powerSiP™ restructures the geometry: it enables a vertically integrated multi-stage VRM and places the voltage regulator directly under the SoC and chiplets. Shortening the delivery path to a vertical drop cuts routing power loss from 12% to 6% — a 50% reduction over the side-by-side baseline.
The same vertical integration raises current density from 0.4 A/mm² to 0.6 A/mm², a 50% increase, while reducing the footprint by 25% compared to traditional side-by-side layouts. For a board designer, those two numbers compound: more current delivered per unit area, in a smaller area, with half the routing loss. The result is a PDN that can feed power-hungry AI and HPC processors without the impedance penalty that lateral routing imposes.
Why Vertical Power Delivery Matters Now
As AI accelerators integrate more compute and memory dies into a single package, their current draw climbs while the area available for power delivery shrinks. A long, lateral PDN adds impedance, and impedance under fast transient loads produces voltage droop — which forces designers to either over-provision the power supply or back off clock speeds. By placing the multi-stage VRM directly beneath the SoC, powerSiP™ allows a large current supply across a short power delivery path, reducing impedance in the PDN and improving system performance and functionality while simultaneously increasing overall efficiency and power density.
As YE Yeh, Vice President of R&D at ASE, explains: "Vertical integration allows a large current supply at a short power delivery path. This successfully reduces impedance and improves system performance while simultaneously increasing overall efficiency and power density."
Efficiency as a Sustainability Lever
Halving routing power loss is not only a performance story; at data center scale it is an energy story. With facility electricity consumption heading toward 1,000 TWh by 2026, every percentage point recovered from the PDN compounds across thousands of racks. ASE frames powerSiP™ in exactly those terms. As Patricia MacLeod, Senior Director of Corporate Communications & Industry Partnerships at ASE, notes: "Our powerSiP platform signifies another step forward in helping enable more efficient power solutions and greener data center energy utilization aligned with our sustainability commitment."
That positioning connects a packaging decision to an operating-cost and carbon outcome — the kind of argument that increasingly reaches beyond the hardware team into facilities and finance.
Built for the AI and HPC Roadmap
powerSiP™ is designed to meet the power and performance requirements of AI and HPC applications, and ASE positions it as a platform that will expand in alignment with industry roadmaps rather than a fixed-spec product. As Yin Chang, Senior Vice President of Sales & Marketing at ASE, puts it: "AI is reshaping knowledge work and business function. Advanced packaging is playing a pivotal role, and powerSiP is evolving to deliver crucial data center system requirements including power and performance efficiencies for AI and HPC."
The platform is available now and complements ASE's broader system-in-package (SiP) and VIPack™ portfolio — so a customer integrating compute, memory, and power conversion in one module can source power delivery from the same partner handling die-to-die interconnect.

Frequently Asked Questions
Q: What is ASE powerSiP™? A: powerSiP™ is ASE's power delivery platform that reduces signal and transmission loss while addressing current-density challenges. It enables a vertically integrated multi-stage voltage regulator module (VRM) placed directly under the SoC and chiplets, improving system efficiency and lowering power consumption for AI and data center applications.
Q: How much does powerSiP™ improve power efficiency? A: powerSiP™ increases power efficiency by 50% in AI and data center applications. It raises current density from 0.4 A/mm² to 0.6 A/mm² (a 50% increase) and reduces routing power loss from 12% to 6% (a 50% reduction over a side-by-side configuration), while shrinking the footprint by 25%.
Q: Why does placing the VRM under the SoC help? A: A vertically integrated VRM shortens the power delivery path from a long lateral route to a vertical drop. This allows a large current supply over a short path, reduces impedance in the power delivery network (PDN), and limits the voltage droop that otherwise forces designers to over-provision power or reduce clock speeds.
Q: How does powerSiP™ support data center sustainability? A: Data center electricity demand is projected to rise from 460 TWh in 2022 to about 1,000 TWh by 2026. By halving routing power loss, powerSiP™ recovers efficiency that compounds across thousands of racks, supporting greener data center energy utilization in line with ASE's sustainability commitment.
Q: Is powerSiP™ available now? A: Yes. powerSiP™ is available now as a power delivery platform and will expand in alignment with industry roadmaps and application requirements. It complements ASE's broader system-in-package (SiP) and VIPack™ portfolio.
