This is getting beyond ridiculous, this standard just needs to be scrapped already.

Anything that needs these kind of solutions is just broken to begin with.

Can’t you recognize a burgeoning business model when you see it?

This is the on purpose birth of corporations releasing broken hardware in order to sell you solutions to fix it. This is on purpose. They are destroying quality standards and conditioning YOU to expect to pay more just for basic functionality.

Move over Windows 11 and AAA video games, there’s a new sheriff of maximum exploitation in town.

Soon nvidia will be bundling mandatory advertisements on a screen attached to every video card sold.

This is not a joke. It’s the future if we allow it.

Vote with your wallets people. You’re dealing with greed and you can turn your back on a person but never greed.

I’ve just gotten a new pc with an 7900xtx so as far as I’m concerned I’ve cast my vote.

“There is no problem with our cards, connectors, or cables, its user error.”

But third-parties are doing things like this why then? Especially if it isn’t needed. NVIDIA once again, letting their gaming division crumble while charging sky high prices.

looks cool with the added screen and such but why is this still such an issue to this day? Any other product would probably be recalled and hit with class actions by now under similar circumstances and instead we're left haggling with manufacturers about repairs if we get unlucky.

To add to concerns, what are the odds that if the worst were to happen to the GPU, that we'd be told using this 3rd party device will void the warranty and absolve them of any responsibility?

They should use UK 3-pin plug. Easy 3000W! 🙄

You're mixing up the 5090 and 6090. It'll come with two of those plugs.

Beast mode. 😎

I'm reminded of a time when an entire industry sprung up in the USA to retrofit Buick Air Suspension to standard passive shocks and coils.

Wonderful, a band-aid. When the 4000 series was released, I had serious doubts about the little thing carrying big current for a PC. Yep, cooling eh?

If a new "innovation" needs this much overcompensation for its flaws, maybe it's not really much of an innovation.

Or, as has been suggested, this is for a new business. The crappy version of The Purpose of a System is What it Does, as applied to the McDonald's ice cream machine (to require service calls, rather than to dispense ice cream)

 

[newtechldtech]

Stop using 12V already ... you want les heat increase the Voltage please.

 

[thisisaname]

The standard seems fine, how it is being implemented is wrong. Pushing 80% of the power down one wire is just plain wrong!

 

[jackt]

this is so wrong...

Hey it works for the food industry and Big Pharma, maybe Nvidia has taken note! 🥳

Idiocracy...

 

[Pete Mitchell]

The engineers who designed this standard should be fired and never allowed to work in engineering again. Same with the electrical engineers at Nvidia.

PCI SIG needs to move PCIe from 12V to 48V to eliminate this and other power issues. 48V power delivery will save money and reduce cabling complexity. PC OEMs will need to encourage power supply OEMs to include high current 48V rails of course. Time to move the PC platform to 48VDC! 12VDC has outlived its usefulness, and just like auto makers have seen, the advantages of 48VDC power delivery will be obvious to all once this change is made.

 

[Alpha_Lyrae]

Honestly, there needs to be current detection and control on every current carrying pin. Fail-safe should be if three pins are only outputting 4.33A, the other three should output only 4.33A instead of pulling greater than 9.0A on the remaining three 12V terminals; 4.33A*6*12V= 312W.

Current load balancing to the lowest current load terminal and a warning to replace cable immediately should be mandatory. The power mode 4-pins are useless and only act like a dumb ground switch to increase total current on each 12V terminal.

Here's where things go wrong:
4.33A*3*12V = 155.88W
9.60A*3*12V = 345.6W (hotspotting likely; may run hot enough to melt housing)
Total: 501.48W
- (5090 is rated for 575W)
Three terminals are running out of spec at 9.6A where temporary excursions to 9.2A are specified. All terminals should be balanced to 8.33A or lower (8.33A*6*12V = 599.76W) when running in 600W power mode.

But, fixing this would involve actual competent designs.

I usually don't go this hard, but this here is a potential fire hazard that may yet kill someone. It's almost criminal negligence here by people who designed and approved this thing.

I really don't think it's as unsafe as that. The wires are getting so hot that the plastic is melting and ruining the connector, but that's still a fair way from starting fires. There appear to have been hundreds, maybe even thousands of 4090 cards that have suffered from this but I'm not aware of any reports where a sustained fire has started inside the PC.

As for the engineers, I think it's a lot more likely that the edict came from high-on that the standard had to deliver 600W at 12V (after all, 12VHPWR...) and they had to keep to the same connectors as PCIe (so limiting the wire gauge).

To approach the same safety factor as PCIe (1.68), you'd need 8 power pins (1.52) instead of 6. Maybe the engineers originally proposed this but were told no, it was too many, by people who had decided that >1 safety factor is enough and if anything goes wrong it's user error or a bad cable so who cares?
