[SOLVED] RTX 4070 Super Not Detected. Is it faulty?

[TemporarySoil]

Hello everyone,

I recently finished my first build. Everything works great except for the GPU, a ZOTAC 4070 Super Trinity Black that is not detected.

The card itself turns on and the fans are spinning, however it doesn't show up in the BIOS, nor in the device manager. Only the integrated graphics card from my CPU shows up. When I try to install NVIDIA drivers, it tells me it doesn't detect any NVIDIA graphics card so I can't install them.

I already tried to remove it, reinstall it but without success. I tried powering it with both the bundled multi 8-pin-to-12VHPWR adapter and the 12VHPWR included in the Corsair PSU. Each tries, the graphics card turns on, the fans spin, but no display and it's not detected by my system.

The line in the BIOS named "Initiate Graphic Adapter" is set to PEG (I can only choose between IGD and PEG), multi-display monitor is enabled and I installed the latest drivers and updates for both the mobo and Windows.

Is my GPU faulty? Or is it the motherboard?
I have trouble believing the motherboard's slots could be defective when everything else works perfectly. Sadly, I don't have any other graphics card to test in the slots and none of my relatives or friends have a PC on which I can try the 4070 Super.

My specs:
Motherboard: MSI MAG Tomahawk Z790 WIFI
CPU: Intel i9-13900K
GPU: ZOTAC RTX 4070 Super Trinity Black
RAM: Corsair Vengeance 64Go (2x32Go)
PSU: Corsair HX1000i

Welcome to the forums, newcomer!

To rule out your platform being the issue, drop the GPU into another(your friend's or neighbors) known working platform.

Motherboard: MSI MAG Tomahawk Z790 WIFI
Out of curiosity, what BIOS version are you on for your motherboard?

The latest I could find on MSI's website. It's from June 26th so roughly a month old.

I don't know anyone with a PC in which I can install this GPU, unfortunately.
However, I have a GTX 1650 from my old computer. Is it possible to mount it on the new motherboard? Also, isn't my PSU too powerful for it? If I fry the GTX, I'm left with no PC.

You wont fry your old card, the GPU only takes as much power as is needed, the rating on the power supply is only for the total amount of guaranteed continuous power. So you can use your GTX 1650 on your new computer with no worry at all of causing damage to it. You can use your old card to test and make sure your system posts, also, are you plugging your video cable into the new graphics card, or into the back of the motherboard? Sorry, I have to ask.

Okay, I'll try the GTX in the new motherboard then.

Yes, I did plug my video cable in the graphics card (I have two monitors, one connects with HDMI, the other one has HDMI and DP). I tried the HDMI port with both monitors and all 3 DP ports. I couldn't get anything to display on screen. I tried to boot my PC with a cable connected only to the graphics card, on one DP, then on one HDMI port it still didn't work.

If I plug both monitors, or only one monitor in the motherboard only (it has 1 HDMI and 1 DP), both ports work. I even get the desktop to display on two monitors at once.

If I plug my monitors on both the motherboard and the graphics card, I only get display from the motherboard.

Yeah its definitely not being detected then, try swapping to that GTX 1650 to see if you get an image. If you don't, check your seating in the PCIE slot, otherwise you may have a bad PCIE slot, do you have enough clearance on the bottom to mount your gpu in the bottom slot? Also check your bios settings, it could be set to use only onboard video, but even then it should still show up in device manager.

I do have just enough clearance for the bottom slot (I have to remove the bottom fans). I tried the RTX there and still no display but the lights turn on and the fans spin.
As for the motherboard I set the graphics to PEG so that it uses the graphics card. Other option is IGP and it's for the iGPU.

I can't mount the GTX right now, but I'll do it later today or tomorrow and I'll update you all.

Are there any EZ-Dbug lights showing on your motherboard? If so which one(s)?

They aren't any once the PC is booted. When it boots up, it lights red -> orange -> white, and then they shut down and the PC boots.

Update:

So I tried the GTX 1650 in the MSI MAG Z790 Motherboard and I still don't get any display. I tried both monitors and both PCIe slots.

I replaced the GTX 1650 in my old PC and it works perfectly, so that means that the motherboard's slots are defective. I'll have to return it and replace it.

I have one last question, when I receive the new motherboard, can I replace my SSD with Windows installed on it, or will I have to format and reinstall windows on the SSD on the new motherboard?

I assume you mean when booting with the IGD? What about if you disable it and try booting with the 4070, do all the lights go out? If they do, it indicates a successful boot which means there should be a picture displayed on one of the 4070 ports. If a light stays on that gives us a clue to what's going on.

If it's the same motherboard you should be able to reuse your existing install. But keep an eye out for oddities just in case.

Just a thought, have you tried reseating the power cables for the GPU on the power supply itself? Also, do you have a GPU that doesn't require pcie power cables that you could use to test with? It would rule out your power supply being the issue. It doesn't have to be fancy, a GTX 210 or 710 or old Radeon HD 5450, just a basic display card.

I'm not sure how to disable the IGD and force a boot with the RTX/discrete graphics card. In the BIOS, I go to Settings-> Advanced->Integrated Graphics Configuration and I have a line named "Initiate Graphic Adapter". I can choose either IGD or PEG. I tried both modes and the LEDs behave in the same way, regardless which mode I choose.
There is also a line called "IGD Multi-Monitor" set to "Enabled". I tried to disable it but nothing changed.
Eventually all the lights go out, regardless which mode and option I pick.

Yes, I tried reseating the cables. I have two sets of cable for the GPU. I tried both but I still couldn't get a display from the graphics card.
I have a GTX 1650 that does not require any cables (my mistake, earlier in the thread I was worried about the cables and the PSU, but turn out I don't need any cables for it), and same result, no display on any of my monitors (my monitors remain in "stand by" mode while detecting that they are plugged) and no LED lights turned on once the PC is booted.
Edit: Forgot to add that, when I try the graphics cards, neither is detected by Windows.

Update: I got a replacement for the motherboard (same model) and my graphics card is now detected!
Turns out the PCIe slots were indeed faulty.

Thank you for your help everyone!
