Hardware Unboxed Falls Victim to Melted RTX 5090 Power Connector as Cable Reaches 175°C
📌 概要
媒体Hardware Unboxed的RTX 5090测试平台再现12V-2×6供电接头熔毁事故。华硕ROG Astral RTX 5090搭配be quiet!电源，线缆温度高达约175°C，热成像证实严重电流不均：部分引脚几乎无电流，单根线承载约22A。奇怪的是电源侧损伤比显卡侧更严重。
⚡ 关键要点
- ▸RTX 5090测试中12V-2×6接头熔毁，线缆温度达约175°C
- ▸WireView Pro监测显示严重电流不均，单根线承载约22A
- ▸电源侧损伤比显卡侧更严重
Hardware Unboxed has become the latest hardware channel to watch a 12V-2×6 connector melt on an RTX 5090 test bench. The setup paired an ASUS ROG Astral RTX 5090 with a be quiet! Dark Power 13 PSU, and host Steve reportedly only caught the fault after touching the cable and finding it hot enough to burn his hand. A thermal camera later confirmed readings above 150°C, climbing to roughly 175°C under load. A Thermal Grizzly WireView Pro caught the underlying problem immediately: a severe current imbalance where some pins carried almost nothing while a single wire was pulling around 22A. Oddly, the damage turned out to be worse on the PSU side rather than at the GPU.
The cable had fused inside the Dark Power 13's connector and needed pliers to remove, while the card's own connector escaped without visible marks. Hardware Unboxed says the cable was fully seated and isn't blaming the incident on installation. This is far from an isolated case, as this connector is notorious for melting. We have reported RTX 5090 connectors melting even after users apply undervolts and power limits, and reported on at least one instance where an ASRock PSU's thermal cutoff saved a card from a similar fate. Some frustrated modders have gone so far as to solder wires directly to the PCB just to sidestep the connector altogether.
