Hey everyone, I just swapped out my old 4060 graphics card for a new 9070 XT, which has three 8-pin power slots. I'm using a Corsair 850e PSU that has a 12V 2x6 splitter, and I've also added another PCIe cable that came with the power supply to fill the requirements for three connections. However, I'm facing an issue where there's no signal coming through the HDMI port on the graphics card. Do I need to use different cables or have I hooked up the power incorrectly? I've seen some similar issues online, but I'm having trouble pinpointing the exact cause. Has anyone experienced something similar? Thanks! Also, I've ordered an additional PCIe cable because Asus support indicated that the setup should have three separate cables instead of a splitter plus one single.

Double-check that your monitor is actually set to the HDMI input. It sounds basic, but sometimes it's the little things that trip us up!
Have you tried using a DisplayPort connection? Sometimes the HDMI might not be set correctly, and switching to DisplayPort can help diagnose the issue.
Using a DisplayPort could definitely make a difference, especially if your monitor supports it. Plus, make sure all your cables are securely connected.
