Modder Tackles Melting RTX 5090 Connector With Custom Dual 8-Pin Board

Tom's Hardware reported that DallasGrave is linked to GRAVEPC.com, which mainly offers custom cooling solutions for small form-factor PCs. Responding to a commenter asking about warranty coverage, the modder said, according to Tom's Hardware: "We're a PNY partner. You'll be able to buy a PNY-specific card with a similar modification directly from us with a full warranty." The modification is not currently listed on the site.

The 16-pin connector issue affects many Nvidia cards because they draw high current through what is effectively a 12-pin connection, with four additional sensor pins. The connector is rated in theory to handle up to 600W. Some melting cases have been attributed to poor pin contact that raises resistance and generates heat.

The 12V-2x6 revision was intended to resolve the melting problems. In early 2025, Nvidia said the issues were over, citing the updated connector on the RTX 50-series. Reports of melted RTX 5090 connectors followed, including one case involving a card running undervolted with a -100W power limit. TechPowerUp also noted that last month Hardware Unboxed observed an RTX 5090 power cable reaching 175 degrees Celsius with a single wire pulling around 22 amps.

Nvidia has increased the Shield TV Pro price by $100 and stopped producing the standard Shield TV, pointing to higher component costs across the industry.
