Investors are pivoting from AI chips to physical infrastructure as data center costs soar. AT&T and Corning signed a $3 billion fiber deal, while analysts highlight power efficiency firms like Vicor and storage providers like Everpure as key beneficiaries of the 2030 AI spending surge.
While Nvidia hits record highs, investors are looking beyond chips to the physical infrastructure supporting AI, including power delivery, optical fiber, and storage, as demand for data centers surges.
Community tests of leaked DLSS 5 builds on RTX 5090 suggest power delivery, not compute, may bottleneck performance: the Founders Edition with a single 12V-2x6 connector hit about a 575 W limit and saw 42–49% frame-rate drops with DLSS 5, while a dual-connector MSI RTX 5090 Lightning Z managed better FPS at higher power draw. In Hogwarts Legacy, neural rendering with DLSS 5 jumped power draw from ~480 W to ~720 W (roughly +50%), underscoring how power delivery could limit DLSS 5 gains. NVIDIA DLSS 5 officially launches Sept 3, with real-world results likely to reveal whether first-party cards or future variants handle the load better.
Tom's Hardware compared RTX 5090 FE (575W cap) with MSI RTX 5090 Lightning Z (dual 12V-2x6) using DLSS 5, finding FE drew about 551W while the Lightning Z hit roughly 723W and delivered about 16–24% higher FPS across several games (Cyberpunk 2077, Hogwarts Legacy, Control), suggesting DLSS 5’s neural rendering is power‑hungry and that power delivery, not just raw GPU power, may be the bottleneck, with NBA 2K27 kicking off DLSS 5 launch tests and more comparisons anticipated.
Satechi has introduced the ChargeView 240W Desktop Charger, a GaN-powered multiport charger that distributes up to 240W across six USB-C ports (C1/C2 up to 140W each, C3/C4 up to 100W each, and the last two up to 30W). When all ports are in use, wattage is split 70W/70W/30W/30W/20W/20W with a live LCD display showing total usage. It ships in Space Black with a desktop stand for horizontal or vertical placement and operates silently with no fan. Power is renegotiated as new devices connect, which can cause brief charging interruptions. Price is $149.99 and availability includes Satechi’s site and Amazon.
Notebookcheck reports on WhatCable, a free macOS app that displays each USB-C cable’s data rate and Power Delivery capabilities per port on Macs, helping users verify if a dock or monitor setup can run at full bandwidth; however, cheap cables without an E-Marker may not report speed, and Thunderbolt 3 cables can be misidentified, with a Pro version offering deeper insights.
The Verge reviews WhatCable, a free Mac app for Apple Silicon that reads data exposed by macOS to show exactly how each USB-C cable performs—speed, power, and potential bottlenecks—by querying the cable’s e-marker and the Mac’s port controller; the app is free at core (with a Pro upgrade for additional diagnostics) and a Linux port is in development.
iPhones (17 series) max out at about 40W and the iPhone Air at 20W, while iPads top out at 45W on base models and up to 60W on the M5 Pro; with Apple no longer including a charger in the box, you’ll need a capable USB‑C PD charger to reach these speeds, and reputable third‑party bricks from makers like Anker or Satechi can deliver them. Battery capacities vary (iPhone 17 Pro Max ~5088 mAh; iPhone 17 ~3692 mAh; iPad 11th Gen ~7698 mAh; iPad Pro M5 ~10290 mAh), which helps explain why larger devices can charge faster when the right charger is used.
Belkin has launched a 14-in-1 Thunderbolt 5 dock in China priced at 2,299 yuan (~$338), delivering up to 140W USB Power Delivery with a bundled 180W adapter and 1m Thunderbolt 5 cable, and it supports triple 4K 144Hz displays for multi-monitor setups.
Amazon has discounted the Anker Nano 67W Charging Station by 30%, now available for $45.99, marking only the third time it has been on sale since launch. With a 4.8-star rating from over 600 reviews, the sleek and versatile charging station is capable of rapidly recharging devices like the 13-inch MacBook Pro and iPhone, featuring two USB-C, two USB-A, and two AC outlets. Made from 75% post-consumer recycled plastics, this limited-time deal offers a space-saving and environmentally conscious charging solution.
