RTX 5090 modder claims to have solved melting power connectors with auxiliary 8-pin board
A hardware modder has developed a solution for the RTX 5090's melting power connector issues by using an auxiliary board to distribute power draw. The modification involves soldering a pickup PCB to the original header to spread the load across three sets of cables, significantly reducing temperatures. The creator plans to offer this fix as an affordable service with a warranty and potentially as a pre-modded product through their partnership with PNY.
- ▪The mod utilizes a pickup PCB soldered to the 12VHPWR header to feed an auxiliary dual eight-pin board.
- ▪Testing at full load for 48 hours showed cable temperatures never exceeded 40 degrees Celsius.
- ▪The modder, affiliated with Grave PC, states that the 12VHPWR connector was never designed for power levels beyond 350 watts.
- ▪Grave PC is a PNY partner and intends to sell cards with this modification directly to customers with a full warranty.
