Asus delivers 2,600W to RTX 5090 to demonstrate the new cableless GPU power connector works

Asus showcases a new 2600W cableless connector for RTX 5090, preventing overheating.

: Amid increasing issues with overheating RTX 5090 power cables, Asus presents the Back to the Future (BTF) design, demonstrating safety at 2,600W. This design eliminates traditional cables, integrating the connector into the motherboard, thus reducing risks and simplifying installations. Tony Yu exhibited the setup's capability to deliver 1,900W without temperature spikes, with the GC-HPWR connector maintaining a low of 35°C at 607W and 41°C at over 1,900W. Asus's BTF aims to reshape industry standards for GPU power supply, providing safer, and potentially revolutionary solutions.

With the growing reports of overheating and melting power cables in Nvidia's RTX 5090 series, Asus has taken a bold step by showcasing its Back to the Future (BTF) design. Asus aims to mitigate such risks significantly through a new cableless connector that delivers power directly via a motherboard-integrated GC-HPWR socket. This demonstration, steered by Asus China General Manager Tony Yu on a Bilibili video, signifies a noteworthy advancement in addressing current design flaws associated with traditional power arrangements, particularly in high-demand systems.

Yu's efforts in the demonstration underscored how the new connector could deliver 2,600W safely to the RTX 5090, surpassing the GPU's maximum stock wattage of 575W by more than four times. This new connector can work alongside newer traditional 16-pin setups without overheating, showcasing compatibility and broad applicability. During extreme tests, Yu managed to push the BTF 2.5's GC-HPWR up to 150A, which remarkably kept its temperature cooler than the 16-pin's 70°C at similar power outputs. Critics and observers have noted this build as an innovative approach towards power distribution in high-performance graphics processing units (GPUs).

Responses from media outlets, including Tom's Hardware, highlighted Asus's demonstration as a potential turning point for manufacturers, encouraging them to adopt safer, modernized power solutions. The report noted over a hundred incidents in previous models caused by traditional cable flaws, including improperly connected cables and tight bends. These issues have plagued the RTX series' users, garnering apprehensive reviews and affecting the series' reputation. Moreover, even with the RTX 5090's new iterations, cases of overheating remain prevalent, pointing towards an urgent need for alternative designs like Asus's offering.

Asus's pursuit to redefine GPU power connectivity through the BTF design could inspire a new standard in custom PC configurations, potentially reducing the need for external power cables and thus the inherent risks. This method could eliminate the extra space commonly required for cables, simplify installations, and reduce component failure risk, appealing to both manufacturers and end-users. The initial BTF design was suited for 600W while BTF 2.5 pressured past 1,000W to 1,900W without overheating, showcasing its capacity to power even multiple high-watt GPUs simultaneously.

The promising results from Asus's tests could catalyze broader industry application of the BTF model, contingent upon hardware makers and consumer adoption. An increase in compatible GPUs and motherboards might accelerate transition towards more compact, reliable, and safer configurations, especially as graphical and computational demands rise. Industry watchers and gamers alike are now watching closely to see how quickly and effectively Asus's BTF system can be realized in production and whether it will indeed overhaul current GPU power standards.
