NVIDIA RTX 50 SERIES - Technical/General Discussion

He should have the 3.1 since he mentioned having 3x PCIe left after the cpu is connected (which needs two)...

Top = 3.0
Bottom = 3.1

If he has the 3.0 then he would only have 1x PCIe remaining.

Awesome, thankyou! Hopefully all goes well for them, will give me some peace of mind plugging mine in once the card eventually arrives in 2026

I am a bit worried with all this power supply talk, I have 2 power supplies which I can use, both 1000W, there are SFX power supplies.
One is a Thermaltake Toughpower SFX 1000 which is ATX 3.1, 5.1 and has 1 H++ 600W cable and the other is a Corsair SF1000 which has two cables into the power supply and 1 600W cable into the GPU.
The Corsair gets a higher Cybernetics rating than the Thermaltake and has very good review around the internet, whereas I can only find one review from Eteknix, where they give it a good rating.

I'm thinking to use the Corsair one and have the Thermaltake a s a spare, what do people think?

I will be using the power supply with a RTX 5090 Founders.

@Madpete - sure, I don’t disagree with anything you’ve said there.

One bad Corsair cable doesn’t mean they are all inherently bad.

But I do take this to mean ‘don’t assume you’re OK just because it’s a Corsair cable’.

And as mentioned, it might be a good idea for anyone with a 3.0 Corsair PSU to get what is now specifically marketed by Corsair as a “H++ / 12V-2x6” adaptor to replace whatever came with their PSU. This is not because the cable spec has changed (it hasn’t), rather manufacturers have probably since ‘upped their game’ when it comes to making cables once the melty melty issues became known… so hopefully more ‘built like a tank’ and less prone to defects in the manufacturing process… such as the defect shown in Jay’s vid.

Hopefully how I’ve written that makes more sense now.

Absolutely yes

Sorry mate wasn't intending to look like arguing! I was agreeing with you in my own words It's absolutely not a corsair (or any manufacturer problem). It's a disaster waiting to happen.
Of course, a cable manufacturer with sloppy tolerances or skimping on requirements is going to be among the first to burn down a house - but NO cable is immune from this.

All good dude, badly worded on my part...

 

[Clarence Boddicker]

Alternatively I would be looking at what MSI is offering, as their yellow cable ends seem to be absolute tanks / well-made.

Their latest psu’s which claim to be 5000 series ready comes with two 12v-2+6, but only 1 PCIe cable. It’s a shame because like you say they look like decent cables. I want the choice on how to connect to the card though.

Go with whichever one you think is best reviewed, corsair has always been a good brand for me. What Jay highlighted could have been a QC error, and it happens with companies. Without further testing we wont know, hopefully some more stuff comes out in the next couple days.

For now, best thing to do, is decide on which psu you want to use. Then to get the pins on the plug of your H++ cable. Make sure theyre even across, none are super low/high compared to others. Check back a few pages here, me and @Nitefly posted a couple pics of ours.

At the end of the day, it could be down to these pins, but from doing other reading, a lot of people dont think it is as contact *should* still be made no matter what. A lot still come back to the lack of shunt resistors being the main cause.

Only half reading but there are 4 pcie cable slots in the top image. One is outside the yellow square.

I wouldn’t worry too much - you’re in a good situation where neither PSU has an H+ socket. So you’re not in a ‘worst case scenario’.

If you go with the Corsair, I think you should buy a new version of the cable that’s “2 cables into the PSU and one into the PSU” (if it’s an old PSU) for this reason:

I'll open the Sf1000 and see what cables come with it, thanks.

Corsair's response.

Funny response lol.

It summarises as: If your 5090/5080 melts, it's because your cable was damaged, so don't blame us and stop using damaged cables that we sell you

Not that I have any sympathy for them, but it must be so commercially difficult for them to walk the line as if they went so far as to say “yeah… double check that the cable we sold you isn’t damaged” it potentially puts them up for provisioning liabilities (i.e. setting aside cash reserves in case the issue turns into fines / claims / other liabilities).

5090 FE arrived today, coil whine anyone lol?

Oh you're right. I didn't see that 2nd CPU & PCIe label at the bottom. However, if his mobo needs 2 CPU power connectors then that leaves only 2 more PCIe sockets... so he should still have the 3.1. I haven't checked to see if AMD's A series chipset use only 1 for CPU.

Yeah, I dont understand how they know the cable was damaged and it caused the issue.....if it's just a melted mess.

 

[Vertigo]

The TLDR is:

- Der8auer’s vid was rushed; there was no way the temps he was recording were accurate, because the cable would have melted way before he could record them.

- The most likely cause for high temps. shown by Der8auer was a defect in that specific cable.

Love that Roman immediately called him out on this ********

OK now Im confused - why would the CPU need two - there's only one CPU power socket on the motherboard? So should I use the 12vhpwr cable that came with the PSU or not - it says it's ATX 3.0 if that makes any difference? Thanks again for any help

 

[aminegriffy]

Absolute joke not a single MSRP 5070ti. £1000+ for a 5070ti is a joke, I should've pulled the plug on the 4070ti super when it was £799 2 weeks ago.

 

[keyser van someone]

If I was in the market for a GPU it would be 5070 Ti for 4K support, seems to be doable with that, the limiting factor being my case size tbh but I cba to change that!

Re:recent cable melting: it's 1 cable and 1 GPU combo on the whole internet? I'd say that's pretty good.

I opened the SF1000 and it comes with two 8 pin connectors to 1 12V-2x6, there is no marking on the cable to designate H+ or H++.
I checked the Corsair website and it states that the SF1000 is ATX 3.1 PCIE 5.1 certified, the only problem with this is that it only states 5.0, 3.1 on the box.

I then read about it on Reddit and on there they say it is just an error on the packaging and it is ATX 3.1, 5.1 certified.

So confusing.
