Gigabyte advising they cannot find a fault with RTX 3090 when I RMA'd due to BSOD

[Distracted]

Did you connect the card to the PSU using two separate pcie 8pin power cables when you were using it, or did you use a pigtail cable where it is one cable that splits into two 8pin at the GPU end?

Avoiding pigtails is something people have found helped in the past.

Using only the cables that came in the box with the PSU of course.

So this is a pic of the PSU I have, its been around 4 years of ownership, so its an old version PSU.

I believe its a Fully Modular ATX PSU

Now I haven't been up to date with the latest tech on power supply units

One chap has mentioned if my PSU is a ATX 3.0 or a 3.1 ? it confuses me as I dont know what the difference is or what my power supply is, if anyone can clarify for me that will be great

The key question is whether is PSU is:

(I) ATX3.0 or 3.1;
(II) Neither.

From that image, it looks like that PSU is a ROG Thor 1200P (really, you are in the best position to verify this).

A ROG Thor 1200-P is not a 3.0 nor a 3.1 PSU. It is an older spec.

This would mean your PSU is vulnerable to the power spikes that we have been telling you about in this thread - many of us have had similar issues.

Replacing the PSU might be the answer and solve the issues for you, but it might not. We cannot say for sure.

If you do buy a new PSU, it should ideally be ATX 3.1 and PCIE 5.1 compliant for future-proofing, as this is the ‘latest spec’ and will have an H++ native power cable for 40 and 50 series GPUs.

what about a Asus ROG Thor 2 ?

what about a Asus ROG Thor 2 ?

Based on my comment on post #34, probably not. Based on this thread Antec HCG looks like a solid choice.

ASUS’s naming convention for their PSUs is maddening. You can now buy a ROG Thor II that is ATX3.1 but earlier versions were not.

As above, @Orcvader (very helpfully) posted some info on the ROG Thor II earlier in the thread.

no it wasn't daisy chained, each 8 pin connector connected via its independent power cable

So Gigabyte explained they did a Time spy Bench and a Final Fantasy in game bench and detected no issues what so ever.

I explained that rather than a bench they might have a better chance to replicate a fault if they did some rendering or run a game at 4k RTX on fully maxed out, it just feels that benching on furmark or timespy may not work the GPU in all areas.

I explained that this particular issue just appeared and that it was previously working fine, and that I tried a 4090 and a 5080 with both perfectly working fine on my PC/PSU

I said that I have a general understanding on how to troubleshoot and GPU and I feel that the card may be misbehaving.

Now they have said that as good will they will issue a like for like GPU, they will post a brand new 3090 (im surprised Gigabyte still have these in stock)

So I cant complain, I think they have done well, now I will need to test this on my PC to see if it displays the same issue, in the meantime just to clear things up I'm gonna order a brand new power supply, either a 3.0 or a 3.1 ATX

But I will test this new 3090 on my old Asus ROG Thor 2021 to see if the new 3090 blacks screen on power spikes, will be interesting.

You were hoping for a free 5080/5090 upgrade

...well played Gigabyte

Sounds like a lot in here were correct and it was probably your PSU. I think you have been very fortunate with Gigabyte.

I do remember that back in the days they were upgrading GPUs. I got a nice upgrade at some point, though I can't recall now models - some mid range from the 2000s. That said, later on when RMAing HD 4870 they decided to replace a ton of components on the board and returned it repaired... Not seen that before, so I've sold it instantly and got a new one as I didn't trust it will last. And to be clear, they gave me a list of parts they replaced and it had 60+ lines so pretty much they rebuilt half of the board and added big smiley face at the end of the list. Someone must've been very very bored in the repair center.
