HighPoint Launches RocketStor 8631D: The Industry’s First 1300W TDP Gen5 x16 Accelerator Enclosure
Fremont, CA – December 2025 – HighPoint Technologies, Inc., the industry-leading provider of high-performance PCIe and storage expansion solutions, has announced the launch of the RocketStor 8631D. This ground-breaking external accelerator enclosure sets a new, non-negotiable standard for AI, HPC and professional media disaggregation by guaranteeing end-to-end PCIe Gen5 x16 bandwidth and providing the sustained power required by next-generation, high-TDP accelerators.
The RocketStor 8631D is engineered as the definitive solution for integrators and architects burdened by the limitations of conventional expansion infrastructure, latency-prone protocols like Thunderbolt, and power-constrained enclosures that throttle the performance capabilities of high-end Gen5 GPUs and FPGAs.

The Solution: Uncompromised Performance for AI & HPC Workloads
The RocketStor 8631D addresses the two most critical pain points in Gen5 external computing: signal integrity and power stability.
“The computational demands of professional AI, Media and HPC workloads are driving TDP into territory that consumer-grade solutions simply cannot support. However, raw power is only half the equation; without a thermal strategy to match, flagship accelerators quickly fall victim to thermal throttling.” said May Hwang, Marketing Director at HighPoint Technologies, Inc. “The RocketStor 8631D is the result of focused engineering—an architectural blueprint for Gen5 dominance. This isn’t just another expansion enclosure – the RoketStor 8631D’s combination of the Astera Labs Retimer, a massive 1300W PSU, and an intelligent thermal management system, offers a sustained performance guarantee for the world’s most demanding triple-slot accelerator cards, such as the NVIDIA H200.”
Guaranteed Gen5 x16 Bandwidth
The RocketStor 8631D ensures that the full 64GB/s of Gen5 x16 bandwidth is reliably delivered from the host server to the accelerator card.
Active Signal Restoration: The enclosure integrates Astera Labs PCIe Gen5 Retimer Technology. This specialized component actively regenerates the PCIe signal, eliminating the signal degradation and jitter inherent in external cable runs, a feature critical for maintaining stable PCIe Gen5 links.
Standards-Based Fabric: Utilizing the PCI-SIG CopprLink standard, the RocketStor 8631D guarantees maximum interoperability and low-latency, non-tunneled communication—a superior alternative to consumer protocols.
Unconstrained TDP and Enterprise Reliability
For today’s power-hungry Gen5 accelerators, consumer grade power supplies invite system instability and performance throttling. The RocketStor 8631D integrated 1300W PSU eliminates these threats, and provides a future-proofed upgrade path for tomorrows cutting-edge GPUs, FGPAs and I/O devices.
Massive 1300W PSU: The RocketStor 8631D provides a crucial margin of overhead for extreme transient power spikes, ensuring that high-value cards like the H200 can operate at their maximum boost clocks and sustained TDP indefinitely.
Universal Physical Support: The robust, triple-slot wide chassis and unobtrusive, Intelligent Cooling System prevents thermal throttling without introducing unwanted distraction into the workspace, protecting your investments and ensuring maximum uptime.
Advanced Intelligent Cooling System
The RocketStor 8631D’s precision engineered chassis architecture and advanced thermal management system ensures it high power delivery translates directly into consistent computational output.
Streamlined Internal Architecture: The RocketStor 8631D chassis is precision engineered, streamlined internal layout minimizes cable congestion and physical obstructions, ensuring direct, unobstructed airflow to critical components.
Intelligent Dual-Fan Cooling System: The enclosure’s firmware leverages a pair of high-efficiency, acoustically tuned cooling fans and integrated hardware sensors to dynamically regulate airflow in real time in response to changing thermal conditions.
This multi-tiered approach provides two key benefits:
Enhances the durability and stability of accelerator hardware by minimizing the thermal load on critical componentry.
Maintains peak sustained output by preventing thermal throttling
