NVIDIA RTX 50 SERIES - Technical/General Discussion

I don't see how it can be a different cable with different power handling but still retain the same plug i.e allowing users to plug in under-specced cables that could cause a fire.

It seems bizarre but I think this was (and still is?) also a problem with USB-C cables for some time… lots of different power handling / not full spec cables frying devices when there was a mismatch.

Not quite the same issue I’m sure, but that’s an example of ‘cables that look the same’ causing damage.

Roughly how much faster will a 5060 ti be over a 3060 ti?
Click to expand...
The 4060ti was less than 10% faster than a 3060ti on average. And that was last gen when the generational improvement was higher than what we're seeing with 5000 series.
Assuming the 5060ti improves from the 4060ti by the same margin, which honestly seems unlikely at this point, we'd be looking at maybe 20-25% better than a 3060ti. At most.

The budget tier Nvidia GPUs haven't been worth buying for a while now. I don't think the 'worst Nvidia generation in recent history' will do much to change that.
At such a budget, one might as well just buy an AMD or Intel alternatives instead.

I had a 5090 preordered, saw a review saying that at full load it took 632w through the connector and I was like "nope. not in a million years"
Even if the connector itself is now "safe" they are pumping way too much power through those units. it is an accident waiting to happen.

People may hate on the 5080, but I am happy with my purchase. and even if the 5090 was only a little bit more money I am not sure I would want it.

Fully agree.
 
I’ve got this cable and plan to use it with a 5090

www.corsair.com

12VHPWR Cable | 600W PCIe 5.0 Power Adapter Cable

The official CORSAIR 600W PCIe 5.0 / Gen 5 12VHPWR PSU Power Cable delivers power from CORSAIR Type-4 PSUs to the most advanced PCIe 5.0 graphics cards.
www.corsair.com www.corsair.com

It says 2x6 in the name, so it’s “new spec”. Yeah?

But on the connector to the gpu it got a very small feint H+ written…so that’s the 12VHPWR “old spec”?

Confused :-(

EDIT. Then you read all cables are identical, it’s the female gpu end that’s (slightly) different.

I'm puzzled why this is only just rearing its head weeks after all the big reviewers published their reviews for the 5090/5080, especially considering how the melting cable/connector thing was present on the 4090. Not one reviewer thought to check the temps on the cables for something that pulls nearly 600w? It seems like it'd be a pretty easy thing to replicate, just put the thing under heavy load.

The problem is that almost all of the reviewers do their testing on an open air bench in an air conditioned room. Most of them freely admit this is done specifically to try and negate any thermal issues and give best case scenario numbers for everything tested.
 
Now would be a good time for someone to design a small piece of hardware that plugs in between the RTX 5000 series toaster and it's power supplying cable.

Such a device could monitor each of the six +12V wires individually and if an unbalance occurs in any of the lines then it kills the power from all cables, protecting the GPU.

Of course, such a device shouldn't be needed in the first place - first it was fake frames, now it's fake phase protection.

I went over this in the thread earlier as there is conflicting info on this.

For example, Seasonic infer that the only changes made are to the female connector in their press video. Yet they also clearly say that only a H++ paired with a H++ will yield all safety benefits. The spec sheets also show that the H++ cables have a higher spec for wear and tear (designed for more connections before degrading).

My hunch - I can’t be sure - is that the technical standards of the H+ and H++ cables are not intended to be the same and all statements that they “are the same” are a simplification / marketing misunderstanding, based on the fact that they both plug into each other and are, in many circumstances, backwards compatible. In which case, Corsair have bodged their representation of what is going on.

It’s a complete mess, because if they were absolutely identical, why would Seasonic say that H+ / H++ is suboptimum…? That wouldn’t make sense either.

Building on my speculation, a reason that Corsair may have bodged it could be to do with many of their cables not being native 12v to 12v; at the PSU side they connect into their micro pcie 8 pin sockets and these cables therefore don’t suffer from the same vulnerabilities. However, this safeguarding won’t carry over to third party native to native cables.

Whatever the answer is, we all need clarity. ASAP.

I do recall reading (here) that the pins on the PSU side are always ‘non-standard’ in respect of their layout, hence PSU manufacturers saying never use cables meant for another brand.

Might be something in that…?

If you pay the Asus tax then you get this somewhat. The Asus astral software monitors the wires and alerts you of issue but it doesn't do anything it's up to you to kill the power

What annoys me about the whole new 2x6 standard thing is it's not a fix to the problem, it just makes it a little harder to plug it in wrong. The main issue of the card will pull the full wattage though anything that's plugged into any part of the plug is unchanged. And to try to fob it all off as user error isn't fair on the consumer. It's not really fair on cable and psu makers either.

Grumble gumble grumble, stupid short sighted nvidia and their stupid connector

This. I wondered about how much current those cables could take when I saw how flexible they were.

A faulty connector on the card that consequently demands more current than the supple cables can take, poor stuff.
