NVIDIA RTX 50 SERIES - Technical/General Discussion

You could argue that they've probably done that to sell more cables though :p

You could probably pull up the PCI-SIG docs and have a look at them if you want a definitive answer, but from what I've seen the cable hasn't changed.

I tried doing this already but membership to review docs seems to cost $5,000 dollars…

Only @Hostile_18 has that sort of cash to blow!
 
I've just watched that video and the question I've only just seen asked in the comments is why all the current is going down those two wires? And not being distributed across all the current wires.
I'm not an electronics engineer but it's probably because the card isn't balancing the load. AFAIK it can't because of the way the connector/cards using 12VHPWR are designed to work in serial.

As in the 12VHPWR is seen/treated as a single connector/cable even though power is being drawn through six cables/connectors.
 
That’s an infographic from Corsair and their marketing team which may be a gross simplification. Everyone that says they are the same can’t seem to provide a more reliable source that this.

Indeed, the manufacturer of the cable that has melted has said there are differences, as per my post above.

All I can say from my personal experience is that trying to get marketing to understand something technical is maddening :p

Hopefully, it is the same - and in support of that, Seasonic’s marketing materials also seem to highlight that it’s the connector that’s changed.
sounds to me like they just want to sell us something new and shiny that in reality is no different apart from the name it is called by ;) Cablemod have been called out on reddit about this as 1 year ago clearly stated : As mentioned below, the cables themselves didn't change actually. This primarily is a change for the GPU connectors directly. :) - MATT CABLEMOD yet a year later now saying oh we have new 12V-2x6 cables available to buy :cry:

Not good guys, rtx5090 full load and the GPU side connector is hitting 90c and the PSU side connector is hitting 120+ degrees

Rtx5090 cards should have two power connectors; one is not enough headroom and it is playing with fire, literally

This vid low key makes me wanna cancel my pre-order.

It blows my mind that Nvidia didn't change something between gens or that they thought going to 575w is sensible.

I'm just going to dig out the cable the card came with and give it 4 separate PCI-E cables.

Right, this vid sets out something else about the new standards which isn’t set out anywhere else… but it does relate to the connector side rather than the cable.


In addition to the new pin lengths, the new standard seems to require a different level of conductivity of the pins. If the cable doesn’t have the new super conductive pins, it won’t reduce heat as intended.

Which to me suggests that super high wattage cards should always use H++ at the GPU and PSU ends.

I don’t think in isolation this explains why the cable melted with the 5090, but it is interesting nevertheless and backs up that you really want to be going H++ to H++ when using a native cable with the 50 series.

Edit: this is discussed in the above vid from 5:00.

Yes, the chart I posted does show things from a specific view which can you fairly argue never existed.

The same applies in all circumstances though and it works both ways; the only cards available at a given time are the cards that were available at that time… so where other cards were unavailable, there will obviously be no dynamic effect across the pricing stack. It also means you can’t go back in time and say “but this was priced at this at a previous time when these other cards weren’t available”.

Here are two other charts that are interesting, posting for a fuller picture regardless of whether they support any viewpoint. You can find the complete set here.

Cards at their prices as they are available today:

5080 value at different price points:

Had they hit $800 the 5080 would have been seen as a big success like a 3080 imo.

That should have been the max price point for the card imo.

Anyway. It's all good. Maybe they learn for the 6080 and in the meantime AMD can reprice their cards higher for their customers and make more profit :cry:

If and its a big if, amd actually manage to put pressure on them with the 9070xt, I could see 6 months down the line a 5080ti launch for 1000 - 1200 with performance between the 4090 and 5090 and the 5080 price dropped to 800. Maybe using the same trick they did with the 4080 super and just pretend to launch a new cheaper card with the same performance.

But who knows. Nvidia seem to far up their own butt with this launch they might not even bother

My PSU has the older spec ASUS Thor P2 (is this referred to as ATX12V or maybe ATX 2.O?)

Using with the ASUS cablemod adapter 12vhpwr old stealthsense original cable.

I was planning to get an AIB 5090 and am presumably "safer" at the GPU side but not at the PSU side.

The PSU is nice and really expensive, so don't really fancy swapping it, especially if it is technically compatible. Doesn't fill you with a lot of confidence, even if the newer designs are failing.

If you use a multi cable adaptor that’s supplied with the GPU, you should avoid the issues that come with using a native cable… hopefully!

I've been fiddling with the OC for a few days and I'm happy to stop here. Absolutely rock solid in every game and benchmark. Overall I'm very impressed with the OC ability of the Palit Gamerock. I found Ninja Giden 2 Black is extremely sensitive to instability, it would crash immediately with a slightly higher core clock, whereas every other game and benchmark was fine with it, but after dialling it back a tiny bit it's also completely stable.


EDIT: Just noticed I forgot to turn XMP back on, it has been fixed :D

Oh god, not one of those x4 8 pin monstrosities? I imagine this is due to the load being divided between the cables? Does a cablemod x4 cable (for example) do the same thing? I currently just have a x2 8 pin cablemod one for the 4090.

Still... :p

Maybe a 9070 soon if AMD truly meant they wanted to gain marketshare :cry:

OFC,but I am stubborn about what I am willing to spend. Also playing older games and indie games helps.

Hopefully an RX9070 but we will see what happens.

Anyway. It's all good. Maybe they learn for the 6080 and in the meantime AMD can reprice their cards higher for their customers and make more profit
:cry:

Aiming for 5% sales share then!

It should do the same thing, but you’re better off using whatever comes with the card to avoid the whole ‘you used a 3rd party cables’ issue, should there be a problem.

If you do use a third party adaptor regardless, it is probably worth going with a H++ (new) version rather than a H+ (old) version… although as discussed above despite some conflicting info, the current consensus is that there is actually no difference between H+ and H++ on the cable side (it’s only the female side of the connector that has changes).

They need to fix the fact the card is pulling so much more power down just one of the cables instead of evenly distributing the power.
Maybe it can be fixed in a bios update? Unless that power is physically going somewhere it is needed instead of being controlled by programming...
