GoKawiilModder builds custom power distributor to curb RTX 5090 connector overheating
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.
GoKawiil's interpretation of the reporting above, not reported fact.
The persistent melting issues with Nvidia's 16-pin 12VHPWR connector stem from uneven current distribution and poor pin contact, problems that worsened as power draw increased compared to older multi-8-pin designs. A third-party fix addressing this at the hardware level could pressure Nvidia or its partners toward design changes, but PNY's past reluctance to honor warranties on cable-related failures raises doubts about whether this specific warranty promise will hold up in practice.
- A modder created a custom distributor module to spread current across more wires on an RTX 5090
- GRAVEPC.com plans to sell a PNY-partnered version with warranty coverage, though not yet available
- PNY's inconsistent warranty history on 12VHPWR issues suggests buyers should be cautious about the coverage claim
