Someone made a CGI of what the rtx 5090 might look like.
I couldn't stop laughing:

Anyone know where I can get those fan clips? And also if I can use the fan clips by salvaging from a CPU cooler?
for Noctua its given by company. you can try asking any seller if they can arrange it for you.
I dont know where but recently(last 3/4 days ago) I read that the power draw was not even across all 3 cables, with one around 300w, and rest <= 150w. I will try to find out the article. If the power draw is uneven as indicated then you can expect a lot more burnt cables and gpus. And also the wire size and quality plays a important role. Hope the manufactures are taking note of this.

Edit 1: Found the Article and added <= sign
First of all this article is more than a month old. After launch we haven't seen any widespread failures reported by users.
As usual Wccftech hypes a seemingly general message from PCI-SIG and creates panic. From the article comments quoting "johnnyguru" whom every-knows as one of the most knowledgeable in the PSU industry. There is a recent video where he explains this very well to a youtuber

So, just to make sure people know where I'm coming from so those who failed maths class and/or cannot be bothered to look up a data sheet while using disqus from their mom's basement can stop needlessly trolling....
Look up the data sheet for a mini-fit jr. terminal and do the math. Even do worst case scenario math, if you wish. The "spec" for the 8-pin mini-fit jr. connector is not 150W as the article states. In fact, it's potentially twice that. The 150W specification came down from Nvidia about 10 years ago and was not based on the power delivery capability of the connector. Think about it. What's the difference between a 6-pin and 8-pin in "power rating"? The 6-pin is for 75W and the 8-pin is for 150W. What's the difference between the two? The 8-pin has two sense wires. Two wires that don't even participate in power delivery, yet somehow magically doubles the capability in power delivery? Think about that for a moment.
In fact, the wire to board current rating for a dual row 8-pin connector using HCS 16g terminals is HIGHER than the rating of the terminals used in the 12VHPWR connector (10A vs. 9A). The truncated, redacted, whatever letter received by wccftech failed to mention/show that the melting connectors were actually the 12VHPWR connectors and not 8-pin mini-fit jrs. And you'll probably note that the letter does not make any mention of mini-fit jr., splitters, adapters, etc. Only that they have witness thermal variance.
As for the part about variance between terminals: You can take ANY multi-conductor terminal, micro-fit, mini-fit, etc., and find a variance in resistance, voltage and thermals; especially at higher loads like this.
This is why I take issue with the article. There is NO problem with using the Seasonic dual 8-pin to 12VHPWR shown here: https://www.tomshardware.co..., for example, and the "concerns of thermal variance" does not apply to it whatsoever.

Buildzoid made a video about this :-
@buBleZ I don't know where he(JonnyGuru) is going with it, but there are few fundamental principles that no one can ignore, the MAX rated capacity of the pin on ATX 3.0 12VHPWR Auxiliary Power Connector is 9.2A @ 30 degrees and if the power draw is uneven(as shown in the article and even JonnyGuru acknowledges that) and if one of the sockets gets past the 9.2A rating then there will be pin melting problems. And this is not an isolated case of socket melting, you can search the internet for pcie socket melting and you will find many such examples(6 pin socket, 8pin sockets). If what he(JonnyGuru) is saying(Rated capacity being higher than what is required) then those should not have happened but it does happen due to various factors that includes uneven power draw, temperate effects, wire and crimp quality, among others.
Manufactures do cut corners and with power draw nearing 600w it is in our best interest to make sure the cables and sockets are up-to standards and it can do what it was supposed to do, dismissing valid points as fear-mongering is not a good approach I would say.
P.S: Just to be clear there are two ratings in everthing, max rating and continious rating, the specification gvies out max rating in Amps and continious rating in Watts. That is why we get 9.2A per pin but only 600W in total power draw. 9.2A x 6 pins = 55.2A x 12v = 662.4W

you can still bring it down up till 24-26 k but i still feel 30 k is not a bad deal w.r.t to what the card offers
I'm assuming that it is Zotac 5yr extended warranty. Make sure to confirm that you will be able to avail the extended warranty when/if you need it. 30k seems a bit on the higher side.

I have just this offer as of now and yes its a zotac card. He has got all the warranty and suport papers with him and an email from zotac confirming the 5 yr warranty. Can't go below 30k as i have done the deal. Hope its a good deal.
