In urgent need of help - regarding 4090 graphics card

Level 7

I am desperately hoping someone can help me as I am now on my 4th Asus 4090 card and can’t get it to work. I have had 2 ASUS ROG TUF OC 4090,s and now it will be 2 ASUS ROG STRIX OC 4090,s.  Only one of them actually loaded up but died within 15 minutes of playing God of War. 
This latest one won’t even install the drivers from Nvidia and doesn’t show up in the Device Manager. My old ASUS 3070 works fine.

This is my PC set up: 
Luan-Li Galahad AIO 240mm HIgh performance RGB CPU water Cooler

Thermaltake tough power GF3 1200W power supply

ASUS ROG STRIX Z690-E Gaming Wifi Intel LGA 1700ATX Motherboard 

Please can anyone help?

4 cards really indicate the issue is not with the GPU. Can you confirm if you're using the supplied power adapter?

Have you tried installing the GPU into the second full-length slot - PCIE16 (G3)?

Flash the motherboard to UEFI Revision 2305 if not done so already.

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090


i have tried with and without the adapter 

I have tried the second full length slot

I haven’t done the motherboard flash. 

my ASU’s 3070 works fine.

Hello, @Smith2503 .

It is recommended that you confirm whether the graphics card is installed correctly, the driver is updated to the latest version and compatible with the OS version, and cross-test with other cables.

Please update the BIOS to the latest version, if necessary.

Thank you.
