Overview

• The GC-HPWR connector built into Asus’s BTF2.5 design sustained over 1,900W for minutes without exceeding 41°C on the ROG Astral GeForce RTX 5090 BTF Edition.
• In an extreme rig setup Asus combined the GC-HPWR and a traditional 16-pin line to feed up to 2,600W into an RTX 5090 without connector failures.
• BTF technology moves the power interface to the motherboard and removes external GPU power cables to reduce risks linked to 12VHPWR melting incidents.
• Although rated for 1,000W, the BTF2.5 GC-HPWR design demonstrated significant headroom, maintaining low temperatures at loads more than double its spec.
• Asus confirmed it will not ship retail graphics cards with both GC-HPWR and 16-pin power connectors activated simultaneously.
