Reddit user DallasGrave, reportedly affiliated with cooling company Grave PC, detailed a mod that solders a pickup PCB to the RTX 5090's 12VHPWR header and routes power through an added dual eight-pin board, spreading current across three cable sets. The user says a card modified this way ran at 550W for 48 hours with cable temperatures staying under 40°C, and plans to offer the conversion as a paid service with warranty, with a PNY-branded version also in the works.

Reddit user DallasGrave, linked to GRAVEPC.com, posted images of a custom module screwed onto an RTX 5090 that splits current across additional wires to reduce 12VHPWR connector temperatures. The fix involves soldering extra connections to the power rails on the card's PCB and routing them through the external distributor. He stated GRAVEPC, a PNY partner, plans to sell a PNY-specific version of this modified card with full warranty coverage, though it isn't yet listed on the site.

A Tom's Hardware reader, Anthony DeMarco, says the 12V-2x6 power connector on his $5,245 Digital Storm Corsa prebuilt melted weeks after he began using it, despite the PC having sat boxed and unused for roughly a year after purchase. The system, built around an Nvidia RTX 5090 and a 1,000-watt Digital Storm power supply, reportedly suffered the worst damage at the PSU itself, with cables fused into the connector.

A Reddit user reported that his GeForce RTX 5090 stopped working after the 12V-2x6 connectors melted on both ends of the modular cable bundled with his ASRock 1600W power supply. He says the card was running stock BIOS settings with a reduced power limit and was idle when the failure occurred, yet PNY denied his warranty claim within a day, citing use of a non-PNY-approved cable.

A Redditor reports their PNY RTX 5090, bought last September, died last month after the 12VHPWR cable connectors melted on both the GPU and PSU ends. PNY denied the warranty claim the same day, saying only its own bundled cable or adapter is covered, even though the user used the cable that shipped with their Asrock PG-1600G PSU rather than a random third-party cable. The card was reportedly idling, unmodified, running stock settings and even underclocked when it failed.

A Reddit user reported finding a PNY GeForce RTX 5080 OC graphics card marked down to $702.56 at a local Walmart, well below its $1,249 listed price and Nvidia's $999 MSRP. The buyer verified the box contents matched the correct model and found the card in good condition before purchase.
