NVIDIA RTX 50 SERIES - Technical/General Discussion

[Nitefly]

Well, I been talking to cablemod and I will say I was left a bit confused.

According to them, my cable “E-Series Pro ModMesh Sleeved 12VHPWR StealthSense” which I brought for my RTX 4090 FE a few years ago and is completely fine is not the same one you can order through there configurator, he went on to say “12V-2x6 connector features longer pins to ensure proper insertion and reduce the risk of overheating” and my original cable is not recommended.

Now it gets weird, the ones on the shop that are just default ones is the one I have now but was told to use the configurator to select 2x6pin for the 5000 series.

So going by that, the old cable and the ones available on the shop are the older ones but going through there configurator I could select 2x6pin for the 5000 series and is more expensive which I just ordered.

Will use the adapter what is supplied with the card until the new cable turns up around 6 to 8 weeks.

What a complete mess this cable spec is, just go back to the old plugs and be done with it.

- this is so annoying to read, because it’s incredibly misleading for him to say that.

The changes to the pin length are on the socket side (on the PSU / GPU), not the cable side (at each end of the cable).

The most important thing for you to identify is whether your PSU has an H+ socket. That’s the thing to ideally avoid using.

If you share the model of your PSU we can help you figure this out.

You know what - nuts to it, I cant be bothered - Ill leave my PC on all the time and I havent got the will or inclination to worry about whether it's going to be a fire hazard. I'll stick with my trusty 3080 FE

Absolutely do not waste money on a new ATX3.1 power supply when you have a perfectly good PSU. 3.1 is actually a relaxation of the spec so in theory (although unlikely), a v3.1 PSU could be *worse* than the 3.0. The sense pins on the 12V-2x6 ports also achieve basically nothing. You don't even need the single 12VHPWR port on the PSU as multiple 8pin into 12V-2x6 (in a single cable atleast) is considered better than the single cable solution*. ATX 3.1 was a complete waste of time.

* mentioned by both the intel engineer and the Corsair psu R&D head.

I was just going to say the same thing as your edit. Yes I agree, if a new connector is needed why make it so feeble as the 12 pin. Just make a full size 24 pin connector with 10 full size power pairs and 4 sense pins.

And spoil the looks of the card.

You know what - nuts to it, I cant be bothered - I'll stick with my trusty 3080 FE - I've just sold it on ebay

Hope you get some good profit on it if you choose auction vs buy it now.

Just to substantiate that and give more details...

Hey guys I was just wondering if you think this is a suitable fire guard for my 5090? Obviously I think the big gaps will let air flow through well, but when it goes up in flames it could more easily spread to the rest of the house?

What you think ?

Flames are the new RGB

To pull in the people that waited and didn't want to pay £2800 for a 5090 or overpay for a pseudo 5070.

The difference in price between the 5080 and 5090 should be coined as The Gulf of Nvidia, in which a submarine codenamed 5080Ti lurks below the surface.

The new 5060 5070ti card is about to be released.

 

[CornyOC]

Holy crap. It is a corsair cable issue!!

LOOK

This is something I have also noticed myself, some of those teminals are varying at protrusion, which means the housing is also not good enough solution for the application. Apparently the spec for these cables is up to 50 insertions, then their function is not guaranteed. Imagine if USB chargers were 50 insertions specced... This just means they need to design better housing for the terminals.

Let's be honest though, the fact these plugs need sensing pins already tells a tale.

Someone send an ambulance. I'm having a stroke. I have just witnessed an MSI Trio OC 5090 sell out instantly for £3,100 (who knows how many were for sale).

 

[HRL]

I wonder what the AMD GPU team are thinking about all of this, i know AMD don't have a card than pushes nearly 600+ watts but i can imagine they won't be moving to this new connector anytime soon. if it aint broke don't fix it i say.

You’re going to be disappointed!

I’m almost wondering whether retail outlets are buying these themselves, just for the sake of keeping up the illusion of high demand.

Because that’s just a silly price.

£600 inflated over what someone else paid, what, yesterday? Who does that. Any individual, conscious human being would process that info and go “that’s a big uplift? nahhhh” other than a very, very wealthy person.

Totally agree!

My PSU is a EVGA GT1000 which does not have any of the 2x6 etc…, so I been using 4x8pin from my old cable for my RTX 4090.

What I am reading between the lines as he would not say “well, our old cables use some materials in the plug that could cause for concern on the 5090” as we can see from one burned FE card that used an older cable from a germen cable company (forgot the name of), now they are making a better plug to go on their cables. That’s what I am reading here from cablemod, there older cables are called “12VHPWR” and on my new cable I ordered it’s called “16p_2x6” so I reckon it’s just a new plug with better materials, or they just trying to get a sale, who knows.

Safety comes first and having the newer cable least gets me some insurance with them if it goes wrong.

I got that notification, could have bought it but had fallen over laughing.

Yup your reading of the situation sounds about right.

The bit that is confusing everyone, understandably so, is that manufacturers are making it out that the changes are making from the move from H+ to H++ (exactly as they told you).

Whereas the reality is that have (or may have) improved their own cables for other manufacturing reasons - which are not ‘standards’ related (unless their old cables were never to standard…. ).

Just to add to my comments, cablemod as now also said after questioning about the plug on the older cables “Its 2x6 pin configuration increases the contact area, providing a stronger structure and improved stability while also preventing overcurrent issues”

Take that how you will, basically saying their older plug is not up for the job for the 5090 and really they should put a note on there store for the default cables are not recommended.

Interesting thought. If these the stock still sells out instantly at these prices in 2-3 months then perhaps something fishy is going on. By then, all the super duper rich folks with money to burn should have a 5090 in hand. I think those (including you!) with an early pre-order have done well, so long as you are willing to be patient and wait a few months. Prices aren't falling for a good 9-12 months I reckon.

@UKGigaProb thinking about it, if you are currently using a “4 way octopus” adaptor for your 4090 (and you don’t want to change your PSU) your best solution is probably to just use whatever equivalent adaptor arrives with your 5090.

That way, if you got an MSI 5090 (or whoever), the GPU maker and the PSU maker can’t accuse you of using a ‘third party cable’ if anything goes wrong.

Plus, the adapters issued with the 5090s should all be made in the H++ era (I doubt any 5090 is coming with a dodgy, poorly made octopus adaptor considering they would be crucified if it melts).

Yeah it’s just a waiting game…

As much as I want to just get the waiting over and done with, I think I might cancel my pre-order if that retailer does decide to increase prices… whether that related to manufacturing costs, tariffs, they don’t have a choice or whatever.

As ‘suboptimal’ as a 5080 is if you’re lucky enough to be able to stretch to a 5090, there is absolutely no way an AIB 5090 is worth >2.5x the cost of an AIB 5080. That’s just silly. I think I’d rather have the 5080… or stick with my 3090 for now.
