I just received my 5070 Ti and installed it, but I'm not getting any video output. My motherboard and other components were working perfectly with my previous 3060 just minutes before the upgrade. I'm starting to suspect that my power supply (a Thermaltake Smart BM650W) might not be enough for this new setup.
I used the 300W splitter that came with the GPU and the dedicated 300W cable from my PSU. I've cleared the CMOS, updated the BIOS, and manually set the PCIe from BIOS to 4.0, but nothing seems to work. I've tried using HDMI and DisplayPort with different cables, which all worked with my 3060. I also did a DDU clean and swapped PCIE slots, but there's still no display, and the VGA light is on in EZDebug.
I'm worried I might have a dead card, but I'm hoping it's just something simple that I overlooked. My PC starts up normally using the motherboard's HDMI and with the 3060 still plugged in. Here are my specs:
- CPU: Ryzen 7 9700x
- MoBo: Gigabyte B650 AX
- SSD: Samsung 990 pro evo 2TB
- RAM: Crucial Pro 2x16 6400 mt/s
- PSU: Thermaltake Smart BM3 650W
- GPU: 3060 12GB (works) + 5070 Ti (problematic)

First off, check if the GPU fans spin briefly when you boot up. If they don’t, it could be a power issue or the card might be dead. Also, your PSU seems underpowered for the 5070 Ti. The recommendation is at least 850W for your Ryzen 7 setup, so consider getting a stronger PSU to rule that out, especially since your current one might not handle the load during gaming.
Yeah, for sure, your power supply isn’t sufficient for the 5070 Ti. The recommended wattage is 850W, and it’s good to have some overhead too. Even if your PSU can start the GPU, it may not sustain power during heavier usage like gaming. Definitely consider borrowing a more powerful PSU to see if that resolves your issue.
I suspected as much! I’ll get a stronger PSU to checkout. Fingers crossed that's the fix.
Thanks for the tip! I haven’t seen the fans spin at all on boot, so I’m hoping the PSU is the problem. I’m trying to get a higher watt PSU to test it.
