Nvidia (NVDA) Explores 800V Data Center Revolution with South Korean Tech Giants

Key Highlights

Table of Contents

Nvidia has initiated discussions with South Korean power equipment manufacturers regarding 800V DC data center designs.
The proposed 800V architecture represents a major upgrade from today’s standard 54V configurations, minimizing copper requirements, cable size, and power conversion steps.
Key South Korean firms possibly involved include Hyundai Electric (267260), LS Electric (010120), and Hyosung Heavy Industries.
South Korea maintains a critical position in Nvidia’s ecosystem through Samsung and SK Hynix’s memory chip production.
Nvidia and SK Telecom are collaborating on A.X K2, a Korean-language AI foundation model, continuing their partnership that began in 2021.

Nvidia is quietly advancing its footprint in South Korea’s power infrastructure landscape, expanding well beyond the memory chip supply relationships already established in the region.

NVIDIA Corporation, NVDA

Reports from Korean publication The Asia Business Daily indicate that Nvidia has approached several prominent South Korean power equipment companies about developing data center systems utilizing 800-volt direct current technology. While industry insiders confirmed the outreach, specific company names were not disclosed in the initial reporting.

The shift to 800V DC infrastructure marks a significant technological evolution. Current data center facilities predominantly operate on 54V systems, necessitating electricity to flow through several conversion phases before powering processors.

Nvidia’s alternative methodology streamlines this to just one DC conversion step. In a company blog post, Nvidia highlighted the advantages — reduced copper consumption, slimmer cabling, and decreased current flow across the entire facility.

This represents a practical response to an escalating challenge. With AI computational demands intensifying, data centers face mounting power consumption requirements, and current infrastructure is reaching capacity constraints.

South Korean Manufacturers Under Consideration

Though Nvidia has not publicly identified its discussion partners, industry analysis points to three probable contenders: Hyundai Electric & Energy Systems (267260), LS Electric (010120), and Hyosung Heavy Industries. Each company maintains significant involvement in emerging energy infrastructure projects.

Market reactions were immediate — LS Electric shares jumped 5.14% while Hyundai Electric advanced 3.02% after the news broke, signaling investor enthusiasm about the potential business opportunity.

Infrastructure compatibility remains the central challenge. Current data center facilities weren’t designed for 800V operations, meaning implementation would demand strategic evaluation of retrofitting possibilities versus new construction requirements.

South Korea already occupies a strategic position in Nvidia’s component sourcing network. The graphics processor manufacturer obtains high-bandwidth memory from both Samsung Electronics and SK Hynix, establishing the nation as an essential contributor to its hardware ecosystem.

Expanded SK Telecom Collaboration

Independent of the power infrastructure developments, SK Telecom has announced ongoing collaboration with Nvidia on A.X K2 — a Korean-language artificial intelligence foundation model being developed through a South Korean government-sponsored program.

The partnership between these companies extends back several years. Their collaboration launched in 2021 when SK Telecom constructed its Titan supercomputer utilizing Nvidia A100 GPUs.

In the previous year, they successfully trained A.X K1 leveraging the Nvidia NeMo dataset. According to SK Telecom, this model contains 519 billion parameters.

A.X K2 will similarly employ Nvidia’s technological framework, with both organizations committing to collaborative research focused on multimodal and vision language models moving forward.

Nvidia stock (NVDA) declined 1.08% at the time of this report.
