ASUS BTF 2.5 Connector on GeForce RTX 5090 Stays Cool Even at 1,900 W Load

ASUS has confirmed that its GeForce RTX 5090 BTF Edition can draw nearly 1,900 W without any signs of overheating, thanks to a robust metal power connector that holds up under pressure. In a series of controlled stress tests led by Tony Yu, General Manager of ASUS China, the BTF v2.5 proprietary GC-HPWR connector remained well within safe temperature limits, outperforming the conventional plastic 16-pin 12VHPWR/12V-2×6 alternative. The latest Back-to-the-Future update introduces a detachable GC-HPWR adapter, giving users the flexibility to switch between ASUS’s metal connector and the standard 16-pin plug. ASUS supplies a small extraction tool that makes it easy to swap connectors, overcoming the original design’s limitation of a permanently attached GC-HPWR adapter and ensuring wider compatibility with existing motherboards, as well as non-BTF-supported boards.

In the first trial, the card drew approximately 670 W, roughly matching the RTX 5090’s typical maximum, and the GC-HPWR connector stabilized between 30°C and 35°C over ten minutes. ASUS engineers rated the metal connector for up to 1,000 W continuous operation, and the results confirmed a comfortable safety margin for maximum load. Tony Yu even increased the draw to 1,300 W, yielding a peak connector temperature of 38°C. In a final extreme test, the load was set to 150 A, driving total consumption above 1,900 W. Even under these conditions, the metal connector held at about 41°C, while the power cables reached roughly 70°C, demonstrating the adapter’s superior thermal performance. Yu’s experiments also showed that the GC-HPWR and 16-pin connectors can share the power load. At a 200 A setting, each connector supplied around 1,200 W to 1,400 W from separate power lines. Although ASUS plans to ship retail RTX 5090 cards with a single connector, this test suggests a possible path for future ultra-high-power GPUs designed for extreme overclockers.
