Yes, it kind of seems logical that if screwed into the case that there should be no lag but in practice this is not how it is.
My MSI 3090 Suprim came with a support bracket and it wasn't until I used it that I realised how much the GPU sagged.
My MSI 4090 is the Suprim Liquid (with 240mm radiator attached) so the PCB section is probably less than half that of a standard 4090 so doesn't really need a bracket.

My Gigabyte 4090 came with a beast of a support bracket I had to screw into the motherboard standoffs and then screw into the card. I could probably stand on the card and not move it
I wonder if the issue isn't so much "sag" as just pure weight.
"Sag", as we generally think of it, puts a torsional stress on the PCIe connector and socket. The basic weight of the card, however is putting a shearing force on the connector/socket.
Since the cracks appear to be around the little "tab" at the end of the connector, which isn't actually in the PCIe socket but just inside the motherboard's "latching" system, is it possible that it's just the pure weight of the card which is putting a shearing force on the main PCIe connector but not on the "tab"?

My Zotac 4090 came with a heavy duty metal support bracket, takes basically all the weight off the PCIe connector.

Mine wasn't a fancy screw in one, but it is magnetic and is rather sturdy too:
Still lol at the size of these cards...

Personally, If I was buying an expensive, upper midrange GPU, I would want it to focus on how it compares to previous generations of expensive GPUS, could not give a rats ass what is going on with an OLD tech based PS5.XBOX, if I did, guess what, I'd own a console LOL....
But I do not, this is a PC focused product and therefore the review should be centered around that sphere.
Perhaps, just maybe, this review is a paid for shill, based upon previous Jensen comments about "midrange GPUS should be around $600 or the price of a high end console", so perhaps thats the angle they are taying to take, having it only compared to consoles makes it "look good", when in fact when its compared to PC sphere only, the value is actually shiet...
The GPU is more expensive and offers a little more performance, while still being VRAM starved for a higher end GPU costing $600. That's the cold hard facts.
But that seems to be ignored and forgotten in your "lets compare this PC GPU to consoles, when the buyers considering it are GAMING ON A PC AND UPGRADING FROM PC PARTS FOR WHICH VALUE IS DETERMINED"...
Your logic is about as terrible as DF's shilling...

See, this kind of support now has me wondering. Whilst this would help alleviate torsional stress on the PCIe connector due to sag, does it help alleviate the shearing stress from pure weight.
Basically, should there be another support underneath the card, near the PCIe connector too?
Man of Honour
I'd say no, when you hold the card, the bulk of the weight is on the opposite side of the PCIe connector as that's where all the heatsink weight is bearing over. The connector area cracks due to the weight of the heatsinks on the opposite end bending that PCB area whilst in the PCIe slot as northridgefix demonstrates in the video posted yesterday. The area my stand is holding the card under is the exact area where you want to have support as that's the main area of weight bearing, by doing this the entire card rests in a more balanced way and the level of stress on the PCIe connector end is what would normally be expected with a much smaller card without a bracket
I'd agree with you on most AIB cards but the FE is different. The FE is fully enclosed in a metal "shell" which is then firmly secured to the three-slot bracket across its entire width. As a result there is virtually no flex or sag with the FE as the whole shell of the card is firmly fixed to the rear bracket.
If FE cards are indeed cracking also then I'm forced to wonder how/why as there shouldn't be any appreciable torsional stress on the PCIe connector as the card isn't twisting or rotating around the connector.
Hence why I wondered whether it's just pure weight creating a shearing force at the connector as this is providing support to the full weight of the card.

Oh yes in terms of FE sure, I thought this was about AIB cards like the Zotac
A lot of aib cards aren't as stiff as coolers aren't a solid hunk of metal unlike FE versions. In effect said AIB cards have quite a bit of flexibility and put nasty torque on the PCB right by the pcie slot. Also, many seem to be damaged when computer is being moved. I'm both cases support of some sort for the card helps a lot
Same and I've been using it since day one. All the previous cards I had sagged over time aside FE ones and AMD stock ones.

I don't believe I've seen even one FE cracked but if that happened I would suspect it's different reason - pure weight and transporting it inside PC without proper safeguards. Shaking such big mass will cause some damage to the PCB or connector eventually.

Yes, until now I believed it was only AIB cards that had exhibited this issue and from that I inferred it would be those where the "chassis" of the card isn't properly attached to the rear bracket allowing a large degree of flex/sag.
It was only that someone earlier commented 4090FE cards were also cracking which surprised me and started me wondering how and why.
Incidentally, in that northridgefix video, the number of Asus cards was shocking.

It's not even about the back bracket, big chunk of metal like on 4090 FE one weights enough to have quite large inertia - that would likely be enough to bend something at least when shaken.
But yes, I got instantly very very glad I didn't buy Asus card this time but Zotac. This one sags without support a bit but at least seems to be relatively crack resistant, especially with included metal support.

Zuck announced Meta is buying 350k H100 Nvidia GPUs for its AI
Zuck is trying to make Jensen richer, think of all the leather jackets he can buy!
350,000 GPUs * $30k each. Though this order size they probably get a discount, maybe $20k each? Who knows, it's Nvidia maybe it's full price. Anyway that's up to $10 billion in revenue for Jensen, from a single customer
And this one order will generate more profit for Nvidia than they make in an entire year selling gaming GPUs to us peasants
