Sapphire Technology is introducing PhantomLink, a novel approach to GPU power delivery aimed at simplifying cable management in high-performance PCs [[1]]. The system, based on the BTF 2.5 standard, routes power directly from the motherboard to compatible graphics cards, offering a cleaner aesthetic without fully committing to a back-connect design [[1]]. Sapphire is launching the technology alongside its new NITRO+ RX 9070 XT graphics card and NITRO+ X870EA motherboard [[1]].
Sapphire Technology has officially launched PhantomLink, a new approach to GPU cable management designed for high-end PC builds. The system aims to improve the aesthetics of custom PCs without sacrificing compatibility with existing hardware configurations.
Rather than fully relocating all GPU connectors, Sapphire is introducing an intermediate solution. This combines a conventional X870E motherboard with an RX 9070 XT graphics card capable of receiving power through a dedicated connector on the PCB. This approach offers a cleaner look inside the PC case by minimizing visible cabling.
At the heart of PhantomLink is the GC-HPWR connector, based on the BTF 2.5 standard. This allows the graphics card to draw power directly from the motherboard. The system doesn’t eliminate the use of the 12V-2×6 power connector entirely, but rather changes its location. The power cable now connects to the motherboard, which then distributes power to the GPU via the PCB, freeing up the front of the system from unsightly cables.
PhantomLink and the BTF 2.5 Standard
The PhantomLink concept leverages the BTF 2.5 standard and its GC-HPWR connector. The goal is primarily aesthetic, offering a cleaner and more integrated look while maintaining compatibility with existing power delivery methods. This is a significant consideration for enthusiasts who prioritize both performance and visual appeal.
However, this approach doesn’t eliminate the potential issues associated with the 12V-2×6 connector. The potential fragility and thermal risks are simply transferred from the GPU to the motherboard, as the power now travels through the motherboard’s PCB before reaching the graphics card.

PhantomLink remains open and modular. Compatible graphics cards feature a removable GC-HPWR connector, allowing them to function with both BTF motherboards and standard platforms using a direct 12V-2×6 connection. This cross-compatibility avoids vendor lock-in and gives users a choice in their system architecture.
NITRO+ X870EA PhantomLink Motherboard
The NITRO+ X870EA PhantomLink marks Sapphire’s entry into the X870E motherboard segment. The ATX-form factor board features a high-end design with a 16+2+1 phase power delivery system utilizing 90A DrMOS, capable of handling over 250W of processor load.

The board supports DDR5 memory up to 8400 MT/s and beyond with overclocking via four DIMM slots. Expansion is provided by three full-length PCIe slots, accompanied by four M.2 slots, two of which are compatible with PCIe 5.0.

Networking is handled by a 5 GbE Ethernet controller and Wi-Fi 7, while the rear I/O includes two USB4 ports. A 20 Gb/s USB-C port is also present on the front panel. Sapphire also emphasizes practicality with an integrated diagnostic display and control buttons. The motherboard maintains a conventional connector layout and does not adopt a full back-connect architecture.

Its role in the PhantomLink ecosystem is limited to routing GPU power via the GC-HPWR, without a complete redesign of the connector layout. Two variants are planned: a classic titanium color version and a lighter-finished Polar Edition designed for white builds.
NITRO+ RX 9070 XT PhantomLink Graphics Card

Sapphire also unveiled the first AMD graphics card compatible with BTF 2.5. The NITRO+ RX 9070 XT PhantomLink adopts a hybrid power system. Its PhantomLink connector can be used with a compatible motherboard, but it is fully removable to allow the use of a standard power cable on a standard platform.

The card features a triple-fan cooling system with six heat pipes. The GPU is in contact with a Honeywell PTM7950 phase-change thermal pad, an increasingly common choice for high-end models.

The advertised boost clock speed reaches 3060 MHz. The backplate features a magnetic attachment system for quick removal, while the fans can be removed individually via a direct-contact mechanism.
