Question my RTX 3080 is faulty?

[talshabi8]

I just built my first PC, everything seemed to be fine until I plugged in a monitor to the GPU's HDMI port- the PC crashed and not turning in since than unless I remove the GPU.

Is it 100% a faulty GPU?

Thanks

What power supply do you have?

 

[talshabi8]

What power supply do you have?

New 850W seasonic

 

[ezskills]

You have a good power supply so it must be the Rtx 3080

Can an outdated bios cause such issue?
Mobo is 570x aorus master
CPU is AMD 3900x

 

[Phaaze88]

There's 21 '850w Seasonic'. Which one?

Seasonic FOCUS GX-850, 850W 80+ Gold

Pull the plug on the pc. Push/hold power button for 10 seconds, all mobo lighting should cease. Reset the cmos by shorting out the pins with a flat screwdriver ( carefully, just needs contact for a few seconds). Plug gpu in, monitor in, power to gpu, boot. Should start.

There's a "Clear CMOS" button on he motherboard, is it good enough? or still need to user a screwdriver?
I tried to hold power button for 10 seconds - doesn't work.
PC seems to be fine without the GPU but with the GPU nothing happened when I turn on.

Are you using a riser cable?
Did you plug the 6+2 ends of the PCIe cable into the gpu?
Do you have another gpu to test with?

No using a riser cable.
Do you mean the 8+8 pins on the GPU? I plugged it with 2 PCI-E cables to the PSU.
I'm using a Palit 3080:

 

[Phaaze88]

Do you mean the 4+4 pins on the GPU? I plugged it with 2 PCI-E cable to the PSU.

There's no 4+4 for a gpu. 4+4 is a cpu EPS connector.
See the following image of a PCIe cable:

Spoiler

See the end of the cable that's 6+2? Did you plug 2 of these into your gpu?
The end that doesn't split is supposed to plug directly into the psu.

Yes I did.

Before I connected the monitor to the HDMI the GPU seemed to be fine - the RGB and the fans were on.
Now no matter what I do the PC does nothing when I turn it with GPU

 

[Phaaze88]

So even the motherboard's LEDs are dead when you have the gpu plugged in?
I think that means you have a short between the gpu and monitor cable.

MB led is on, but nothing happens when I turn on with the GPU (no case lights, no fans, no CPU, etc)

 

[Phaaze88]

I think there's a short then.
Nothing's dead, but the system is unresponsive with that gpu installed, and completely alive when it isn't.

Have you tried it in the 2nd slot?

Yeah I tried it in both PCI-E slots.
Unfortunately I don't have another GPU to test it.

Bios update has nothing to do with this issue right?

 

[Phaaze88]

No, because the system is refusing to power on to protect itself...

 

[Phaaze88]

Do you have another cable to test with? You can at least rule that out.

 

[talshabi8]

Yes I tested it.
By the way, when I try to turn on with the GPU I hear a small click noise.
Is it possible that the PSU is not able to handle the GPU?

No, that's not the case, but I'm not able to tell you what the clicking is.

 

[Nemesia]

PSU clicking once when the system start and/or when the system shutdown is normal. It's a relay that turn on and off.

At 22 seconds. Sounds like this?

Yes.
So I guess it is a faulty GPU

Weird update:
I did 2 things:

1. Removed the battery for 1 minutes
2. Update the bios using the q flash+

Than the computer tuned on with the GPU, lights, fans and everything BUT no signal on the monitor (tried both HDMI and DP).
I connected the GPU to a different PCI-E slot and now again the PC is not turning on no matter which PCI-E slot I use.
Also tried to remove the battery for 1 minute again with no help.
