RTX 5090 melting connector issue persists despite Nvidia's fix
Melting 12V-2x6 connectors on Nvidia's flagship RTX 5090 remain a problem: tests show up to 22A on a single wire out of six against a 9.5A rating, with cable temperatures reaching 175°C. The cause is that all six 12V lines feed a single input with no load balancing, as was the case on the RTX 30-series.
- der8auer measured 22A on two of six wires of an RTX 5090 FE versus a 9.5A per-pin rating
- Hardware Unboxed recorded 175°C on a ROG Astral RTX 5090 cable
- DLSS 5 in NBA 2K27 pushed RTX 5090 power draw from 465W to 575W
- The 12V-2x6 connector has 1.5mm shorter sense pins but no current balancing
