Who Quanta is
Quanta Computer (2382.TW) is Taiwan's largest notebook contract manufacturer. The live P&L is no longer that company. From Q1 2026, servers have been more than 80% of sales, and AI has been 75–80% of server revenue. It is not on NVIDIA's published 800 VDC component list. It sits in the same slot as Foxconn and Wiwynn: the listed company that has to ship the cabinet.
Business mix
By the first half of 2026 the weights were:
- Servers — more than 80% of sales, AI plus general compute. AI is guided to 80% of that server line in the second half of 2026.
- Notebooks — the rest of the book. First-half 2026 shipments 11.5 million units, better than the prior "flat to slightly up" guide, then guided down more than 20% in Q3 and double-digit down for the full year as memory and CPU prices squeeze brands.
- Automotive / smart driving — still growing double-digit, but a low-single-digit mix because AI servers crowd it out.
Where it sits in the NVIDIA 800 VDC stack
The integrator on NVIDIA's diagram: compute rack, power shelf, 45°C loop. Quanta does not claim an 800 V SKU. The August 2026 call never said 800 V or HVDC.
What it did date is the factory. AI-server capacity is guided to double by end-2026 versus end-2025 (Thailand and California taking more than 80% of first-half capex). The NT$19.7bn AUO Huaya plant in Guishan is meant for 2028 AI-server backend assembly, next to the R&D HQ and the existing server lines. Management's test-power sentence is that the building already has high-voltage supply from its panel days, which it says fits outgoing test of AI servers. That is plant infrastructure, not NVIDIA's single-ended 800 VDC rail.
Customers: large CSPs as the main AI-server book, plus NeoCloud GPU and ASIC racks in small volume. Some high-ASP parts move to consignment from Q3 2026, project by project — GPU and ASIC both. Visibility is talked about through 2028.
Coverage note
One note, Q2 2026 (13 August). Earlier 2026 decks exist in the Chinese IR archive; this collection starts at the call that dated 2028 capacity and the Huaya plant.
