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.
