Asus Unveils GeForce RTX 5090 Variant Capable of Over 1000W Power Delivery via Single Cable

• June 3, 2026

During Computex 2026, Asus revealed a new variant of Nvidia’s GeForce RTX 5090 graphics card, labeled the ASTRAL-RTX5090, which introduces a notable advancement in power delivery technology. By significantly raising the card’s operating voltage, Asus has increased its maximum power consumption capabilities well beyond the conventional limits.

Revolutionizing GPU Power Supply

The standard GeForce RTX 5090 typically operates at a power envelope of around 600 watts. Asus’ ASTRAL-RTX5090, however, pushes this ceiling to approximately 1000 watts. This leap was achieved by increasing the voltage supplied to the graphics card from the usual levels up to 48 volts, which is a fourfold rise compared to standard configurations.

By elevating the voltage to 48 volts, Asus managed to reduce the current required to deliver this higher power, allowing the massive power draw to be handled through a single power cable. This approach contrasts with the typical setup where multiple cables are required to meet the power needs of high-end GPUs.

The design innovation not only aims to simplify power connections by eliminating the need for multiple cables but also potentially enhances power stability and efficiency by minimizing current flow and associated losses.

Despite the substantial increase in power capability, specific details regarding the cooling solutions, overall performance gains, and market availability of the ASTRAL-RTX5090 variant were not disclosed during the presentation.

This development underscores a trend in GPU engineering where manufacturers seek to push performance boundaries while addressing the practical challenges of power delivery and cable management. Increasing voltage to manage wattage more effectively could influence future designs of high-end graphics cards.

Asus’ demonstration of the ASTRAL-RTX5090 highlights the company’s commitment to innovation and its ability to rethink hardware design fundamentals to support increasingly demanding components.

Asus introduced a modified GeForce RTX 5090 version at Computex 2026 with voltage quadrupled to enable over 1000W power via one cable.
