I bought an ASUS Prime RX 9070 XT graphics card and an ASUS Prime power supply rated at 750W Gold. The graphics card has three power connectors, and I'm not sure how they should be connected. Which cables should I use, and is this power supply sufficient?

Before powering on, confirm that every connector is fully seated and that you’re using GPU/PCIe cables—not the CPU/EPS cable. Follow the installation guide for the card and power supply, since forcing an incompatible cable can damage the hardware.
A 750W Gold unit may be enough depending on the exact model and the rest of your system, but verify the graphics card and PSU requirements first. The wattage rating alone doesn’t guarantee that the PSU has the required number of dedicated PCIe cables. Ideally, use separate PCIe cables for each connector rather than relying on a single daisy-chained lead.
Use all three power sockets on the graphics card. Connect them with the PSU’s cables labeled PCIe or GPU, usually using the 6+2-pin ends. If the power supply doesn’t include three suitable PCIe connections, don’t try to improvise with random adapters or extenders—check the PSU manual or use a properly compatible cable.
The PSU is rated at 750 watts and Gold efficiency, but I’ll check whether it actually includes three dedicated PCIe cables and compare the manufacturer’s requirements.
