當AI伺服器機櫃的單櫃功耗從數十千瓦急遽攀升至 100 萬瓦級別，硬體供應鏈的競爭焦點已不再局限於運算晶片的算力堆疊，而是被迫推向供電網絡與熱管理的物理極限。新世代機櫃整體採購成本達數百萬美元，液冷散熱技術的滲透率在最新架構中預估正式突破 53%，同時內部架構加速倒向 800V高壓直流系統。這場跨越伺服器與消費電子的硬體升級，帶動關鍵零組件價格出現數倍甚至數十倍的跳升。供應鏈的價值分配正經歷一輪劇烈重整，使傳統電子零組件廠躍升為規格制定的核心受益者。As AI server rack power densities climb from dozens of kilowatts into the megawatt range, hardware supply-chain competition has migrated beyond silicon compute density to the physical boundaries of power distribution and thermal engineering. With next-generation rack systems commanding multimillion-dollar price tags, liquid-cooling adoption is projected to eclipse 53% in latest-generation architectures, while internal topologies shift rapidly toward 800V high-voltage direct current (HVDC) designs. This industry-wide upgrade cycle across enterprise and consumer electronics is propelling unit prices for mission-critical components by several-fold, reshuffling value distribution and elevating legacy component suppliers into essential architectural partners.

高壓直流重構電源零組件價值鏈HVDC Architectures Reshape Power Component Value Chains

伺服器內部電壓邁向 800V高壓直流架構，徹底打破了傳統零組件的價格天花板。在高壓與高安培運作環境下，高規格繼電器單價大幅躍升至傳統規格的數十倍。松川精密 7 月營收達 9.86 億元、年增 99.38%，凸顯AI伺服器電源供應器對高壓特規零件的強勁需求；瀚荃切入板端電源連接器後，第 2 季毛利率拉升至 37%，營運動能隨伺服器出貨放量而擴張。與此同時，單一高階機櫃消耗的MLCC數量突破 60 萬顆，接單出貨比攀升至 2.2 的高水位，特規料件全面出現交期拉長與溢價，形成供不應求的賣方市場。The transition to internal 800V HVDC architectures has effectively shattered traditional price ceilings for passive and power components. Under extreme voltage and amperage loads, unit pricing for high-spec relays has surged to multiples of standard components. Relay supplier Song Chuan Precision reported July revenue of NT$986 million, up 99.38% year-over-year, reflecting surging demand for specialized high-voltage components in AI server power supply units. Similarly, CviLux expanded its second-quarter gross margin to 37% after penetrating on-board power connectors, buoyed by accelerating server shipments. Meanwhile, MLCC consumption has surpassed 600,000 units per advanced rack, driving book-to-bill ratios to an elevated 2.2, stretching lead times and securing pricing premiums in a tight seller's market.

旗艦終端催生極限散熱與機構革命Flagship Devices Spark Thermal and Mechanical Redesigns

規格升級浪潮同步席捲消費性電子領域。蘋果推出定價 1,999 美元的橫向折疊機iPhone Duo，並在iPhone 18 Pro系列中導入台積電 2 奈米A20 Pro晶片。面對先進製程晶片的高負載運算與極致薄型化機身，散熱成為決定終端效能的關鍵瓶頸。iPhone 18 Pro將均溫板表面積擴大至前代的 3 倍，iPhone Duo更採用雙片超薄均溫板與超過 100 個微型零件構成的精密鉸鏈。這項工藝轉變使奇鋐奪下高階手持裝置超薄均溫板約 5 成市占，新日興則獨拿軸承訂單，推升高階機構與散熱供應商的單機價值。The high-spec hardware wave is echoing across consumer flagships. Apple has introduced the horizontally folding iPhone Duo at $1,999 while deploying TSMC's 2-nanometer A20 Pro processors in its iPhone 18 Pro series. Confronting the thermal envelope of cutting-edge silicon within ultra-thin enclosures, thermal management has become the definitive performance gatekeeper. The iPhone 18 Pro expands its vapor chamber surface area by three times over its predecessor, while the iPhone Duo utilizes dual ultra-thin vapor chambers paired with a high-precision hinge composed of more than one hundred micro-components. This architectural shift has enabled AVC to secure an estimated 50% market share in ultra-thin vapor chambers for high-end handsets, while Shin Zu Shing captured exclusive hinge orders, lifting dollar content for structural and thermal suppliers.

代工營收暴增背後的物料成本考驗Mounting Bill-of-Materials Costs Test ODM Margins

硬體升級的拉貨潮迅速反映在代工組裝龍頭的帳面營收上。緯創 8 月合併營收達到創紀錄的 4,600.65 億元，年增 166.46%，前 8 月累計營收已突破 2.51 兆元大關；廣達單月營收亦衝上 4,239.71 億元，展現龐大的組裝出貨動能。然而，營收的倍數增長並未完全消除市場隱憂。包含高速記憶體與特規銅纜在內的關鍵物料價格暴漲，使整體物料清單成本急遽攀升。若組裝廠無法將高昂零組件成本全額轉嫁給終端雲端服務商，代工業者可能陷入營收創新高但毛利率遭到實質稀釋的獲利高原期。The hardware upgrade wave translated into blistering top-line gains for leading contract manufacturers. Wistron posted record August consolidated revenue of NT$460.065 billion, a 166.46% surge year-over-year that lifted its eight-month tally beyond NT$2.51 trillion. Quanta Computer similarly logged August sales of NT$423.971 billion, evidencing immense system assembly volume. Nonetheless, explosive top-line growth masks margin risks. Surging prices across high-speed memory modules and specialized copper interconnects have driven up overall bills of materials. Unless original design manufacturers can fully pass along inflated bill-of-materials costs to hyperscalers, assemblers face the prospect of a margin-dilutive plateau despite milestone revenues.

本刊判斷，零組件升級已由單純的運算規格競賽，演變為散熱與電力傳輸的物理瓶頸攻防。後續觀察重點在於雲端巨頭對龐大資本支出的承受力，以及硬體溢價能否順利向下傳導；同時需密切追蹤高階特規料件交期變化，這將是判斷供應鏈獲利動能能否延續至明年的關鍵指標。In our assessment, component upgrades have transformed from a mere computing race into a contest over thermal and power engineering bottlenecks. The critical questions ahead are whether hyperscalers can sustain this pace of capital expenditure and whether hardware premiums can continue to be passed downstream. Investors should closely monitor lead times for specialized high-spec components as a barometer for whether supply-chain earnings momentum can extend into next year.
