Le GeForce RTX 5090 non smettono di fondersi, nemmeno coi cavi 12v-2x6

24 June 2026 at 16:25

Ci risiamo, ennesimo caso di scheda grafica NVIDIA top di gamma danneggiata dal famigerato cavo di alimentazione. Questa volta sembra che sia successo con la variante aggiornata, quindi il cosiddetto 12V-2x6 al posto del precedente 12VHPWR, pensato proprio per risolvere i suoi problemi. L'ultimo episodio coinvolge una fonte particolarmente nota nella comunità hardware. Il sito specializzato Club386 ha documentato il danneggiamento di una RTX 5090 Founders Edition durante una sessione di test.

Le immagini pubblicate mostrano pin anneriti, plastica deformata e danni evidenti sia sul connettore della scheda video sia sul cavo di alimentazione. Secondo quanto riportato, il sistema era alimentato da un Be Quiet Dark Power 13 da 1000 watt collegato tramite un singolo cavo 12V-2×6 nativo, correttamente installato e conforme alle specifiche previste.

Il 12V-2×6 era stato progettato per migliorare la sicurezza del precedente 12VHPWR grazie a pin di rilevamento modificati e a una forma migliorata dei pin di potenza. Tuttavia, questo risolve solo parte del problema. Le GeForce RTX 40 e RTX 50 non hanno circuiti di monitoraggio del carico, quindi se per qualsiasi ragione uno dei sei pin di potenza non fa bene contatto tutta l'energia viene trasferita attraverso i restanti cinque. Il problema è che i fili elettrici hanno una sezione molto al limite calcolando che una RTX 5090 può arrivare ad assorbire anche 600 W nei carichi AI o nel gaming.

Nvidia rallies telcos around AI agents at DTW Ignite

23 June 2026 at 07:00

Nvidia and telecom partners including SoftBank Corp and NTT Data plan to demonstrate a stack of data, models, simulation tools and secure runtimes at DTW Ignite 2026, aimed at helping operators move from task-based automation to fully autonomous network operations.

The company argues while generative AI has delivered strong returns in network management, customer care and back-office automation, most of the impact has been limited to speeding up predetermined steps while humans still correlate insights and direct next actions.

Nvidia’s claims automation is now “the launchpad to autonomy” rather than the end goal, with AI agents expected to proactively monitor for problems and coordinate changes across network, IT and business systems while keeping humans in control of policy.

Nvidia cites figures showing 54% of telecom operators view data-related issues as their biggest obstacle to building telecom-specific AI models, largely because the most valuable network and customer data is too sensitive to use directly for training.

SoftBank Corp is tackling the problem by using Nvidia’s NeMo Safe Synthesizer and NeMo Anonymizer tools to generate privacy-preserving synthetic datasets which mirror the structure of real network performance and configuration datasets.

Those datasets are being used to fine-tune its Large Telecom Model (LTM) and build specialised network agents.

On the runtime side, Nvidia stated its NemoClaw blueprints and OpenShell secure runtime are designed to give long-running agents policy-based guardrails and sandboxed access to telecom systems, allowing operators to expand agent responsibilities while keeping behaviour auditable and governed.

NTT Data is applying Nvidia’s open Nemotron models alongside NemoClaw to build agents which track long-term network performance trends and escalate anomalies to specialised research agents for deeper telemetry analysis.

Other partners building on the same framework include: AdaptKey, which is piloting self-healing 5G agents with operators; ServiceNow, which is bringing its Project Arc incident-response tooling to telecom network operations centres; and Tata Consultancy Services, which is developing a multi-fidelity AI sensor architecture for faster anomaly detection.

Simulation is the third pillar of the effort, intended to let agents test recommendations in near-real-time digital environments before acting on live systems.

Software company Forsk stated its GPU-accelerated radio propagation model now achieves ray-tracing-level accuracy up to 200 times faster than CPU-only systems, while Viavi Solutions reports order-of-magnitude gains in RAN simulation throughput after shifting workloads to Nvidia’s RTX Pro 6000 Blackwell GPUs.

KDDI and KDDI Research, working with Nvidia, Keysight and Samsung Research America, are building a high-fidelity RAN digital twin aimed at the 6G era, allowing multiple autonomous agents to simulate scenarios for future radio conditions and traffic shifts.

Nvidia rolls out robot safety platform

22 June 2026 at 16:24

Nvidia unveiled what it described as the industry’s first full-stack safety platform for physical AI designed to accelerate the deployment of humanoid robots in industrial environments.

The company said its expanded Halos platform combines AI compute, system software, sensors and inspection tools into a single safety architecture aimed at helping robotics companies build and certify autonomous systems operating alongside human workers.

The chipmaker explained as robots become more autonomous and increasingly rely on AI foundation models, distributed sensors and accelerated computing, “scaling these systems requires a full-stack safety architecture” before they can be trusted to work alongside humans in factories, warehouses and logistics operations.

The stack includes Nvidia’s IGX Thor industrial computing platform, Holoscan Sensor Bridge for sensor connectivity and Halos OS software stack.

Nvidia also opened its Halos AI Systems Inspection Lab to robotics partners, aiming to help them complete pre-certification testing and validate safety systems before approaching regulators.

Digit
Humanoid robotics company Agility Robotics is the first partner to adopt elements of the platform into the proprietary safety system for its Digit humanoid robot, which is already being deployed for industrial applications with customers including Amazon, Schaeffler and Toyota Motor Manufacturing Canada.

The robotics player will also use Nvidia’s Inspection Lab to validate Digit’s safety-related software, AI components and cybersecurity protections against strict standards.

Agility Robotics CEO Peggy Johnson said: “For humanoids to deliver value at scale, safety has to be built into the robot and validated across the entire system.”

She added the partnership with Nvidia “extends our leadership in responsible automation”, describing it as “a non-negotiable requirement for bringing humanoids safely into industrial workflows”.

Deepu Talla, VP of robotics and edge AI at Nvidia said: “Physical AI is transforming how factories, warehouses and logistics operations work. He added developers will be able to “harness Nvidia’s proven autonomous vehicle safety foundation to develop safer robots faster” and deploy systems “alongside workers with greater confidence”.
