PC Graphics

[Primalek]

GPU: 7900 xtx sapphire nitro plus

CPU: Ryzen 7 9800x3d

Motherboard: MSI x870e TOMAHAWK WIFI

BIOS Version: 7E59v2A31

RAM: 32GB G. Skill Trident Z5 6000mhz cl 30 DDR5

PSU: EVGA 850 Fully Modular (from his old pc)

Case: NZXT H6 Flow

Operating System & Version: WINDOWS 11 PRO

Description of Original Problem: The PC works and outputs image if it’s connected to the motherboard, the graphics card has the LED strip running but the fans are not spinning and it’s not showing up in either device manager or adrenalin. Brand new build which I have built for a friend of mine

Troubleshooting: I’ve done some troubleshooting like updating the bios making sure the card is fully seated in the PCIe slot, I made sure all the connections between the GPU and PSU are connected and fully seated.

Nothing that I have done allowed me to view an image through the GPU the PC will boot with or without the GPU just fine, could it be just a bad GPU? Did my friend get unlucky or am I missing something?

All the help I can get will be greatly appreciated.

Assume the monitor is connected to the 7900 port?

Checked bios for 'initial display first' is set to PCI gen?

Yep, check all the ports on the card to make sure, both dp and hdmi no display on either of them.

Yes, initial display is set to PCI I even went as far as disabling iGPU and still no image, you can hear the windows sound meaning it's booting just no image.

Also doesn't show up in device manager which is quite concerning (tried show hidden devices still nothing).

When you first turn on the pc, if the GPU is getting power, you should see the fans spin, even if it is a 0 rpm fan design.

One potential issue could be that the PSU is multi-rail and all the power connections are on same rail and cannot provide enough power. Otherwise, it could be a dead gpu.

Thanks for the reply,

The PSU is Evga P6 Platinum 850w single rail, we put a 2080 Super in and 3080 both worked just fine we ended up sending the card back hoping the next one is not DOA.

Thank you for the help!
