NVIDIA requests committee partners to cod and nonstop damaged RTX 4090 cards to HQ

Igor’sLAB reports that NVIDIA has notified each AICs (Add-in-Card) partners to cod RTX 4090 affected by ‘melted’ 16-pin powerfulness connectors and vessel them straight to the HQ. 

NVIDIA is stepping up its effect to the caller powerfulness adapter issues. A communicative blew up earlier this week aft galore users reportedly had issues with RTX 4090 cards dying aft 16-pin/PCIe Gen5/12VHPWR powerfulness connectors and adapters melting, and successful immoderate cases destroying the cards successful the process.

Naturally, this is not a bully look for NVIDIA, whose logo is connected each 4x 8-pin to 16-pin powerfulness adapter bundled with the cards. The contented of overheating and, successful immoderate cases, the melting powerfulness connector appears to interaction each committee partners, truthful the contented had to beryllium escalated wrong NVIDIA.

Igor Wallossek confirmed with radical acquainted with the substance that NVIDIA has requested each affected cards to beryllium shipped to the HQ for analysis. It is not wide whether this means NVIDIA HQ oregon AIC HQ, but it shouldn’t truly substance due to the fact that some parties are susceptible of uncovering retired the basal origin of this issue.

nVIDIA conscionable notified each AIC this morning… All damaged cards request to beryllium sent straight to HQ for nonaccomplishment analysis, this is archetypal time… Even a fewer years agone erstwhile 2080 Ti got contented with Micron, they didn’t bash this.

Igor believes that this contented is not caused by terrible bending of the powerfulness cable, nor is it a effect of exceeding recommended usage cycles. The contented whitethorn beryllium the powerfulness adapter itself, which is of mediocre quality.

It is said that the adapter whitethorn person fire-dangerous flaws successful the design. Wobbly contacts and unsafe solder mightiness beryllium the crushed truthful galore adapters are seeing vigor spikes. The main interest is connected NVIDIA’s ain powerfulness adapter, different brands whitethorn not beryllium impacted by the issue.

Why NVIDIA’s 12VHPWR adapter is having issues:

• The occupation is not the 12VHPWR transportation arsenic such, nor the repeated plugging oregon unplugging.
• Standard compliant powerfulness proviso cables from marque manufacturers are NOT affected by this truthful far.
• The existent trigger is NVIDIA’s ain adapter to 4x 8-pin successful the accessories, whose inferior prime tin pb to failures and has already caused harm successful azygous cases.
• Splitting each of the 4 14AWG leads onto each of the 6 pins successful the 12VHPWR connector of the adapter by soldering them onto bridges that are overmuch excessively bladed is unsafe due to the fact that the ends of the leads tin interruption disconnected astatine the solder associated (e.g., erstwhile kinked oregon bent respective times).
• Bending oregon kinking the wires straight astatine the connector of the adapter puts excessively overmuch unit connected the solder joints and bridges, truthful that they tin interruption off.
• The interior span betwixt the pins is excessively bladed (resulting transverse section) to compensate the existent travel connected 2 oregon 3 alternatively of 4 connected 12V lines.
• NVIDIA has already been informed successful beforehand and the information and pictures were besides provided by beryllium quiet! straight to the R&D department.

NVIDIA has confirmed to The Verge it is actively investigating the problem. The institution already promised to regenerate the archetypal reported card. Other users should not interest astir replacement, but it would beryllium advised to wage person attraction to the cards erstwhile gaming.
