Can 12VHPWR issues be fixed?

A Computer Guy · Jan 4, 2024

Saw this video today. It seems using 12VHPWR isn't an issue that is quite fixed yet.

Started a friendly poll. What do you think?

Do you have a high power GPU with this connector and are you still worried after the last round of drama?

They doubled and tripled 6-pin and 8-pin connectors why did card engineers not double the new 12VHPWR connector?

ThrashZone · Jan 4, 2024

Hi,
Sure just plug it in all the way.
Not sure why they need a plug just solder the wires on and leave a longer pigtail for 2x6 or what ever.

dgianstefani · Jan 4, 2024

Already have been, besides the original issues were literally user error or third party manufacturers not following design guidelines.

The connector has been made even more idiot proof with the 12V-2x6.

It's fine....

ChettManly · Jan 4, 2024

1. Has any card not a 4090 actually ran into a problem?
2. Has anyone shown a properly plugged in 1st party cable burning up?
3. Have they not redesigned it with 12V-2x6 to prevent rich idiots from burning up their $1500+ GPUs?

There is no engineering reason to go back to running multiple cables. The idiot proofing will be sufficient.

12v-2x6 already fixed it dude.

Unless I missed something isn't der8auer's argument using new 12v-2x6 and that was what he was using in the video? (edit)
At the 11 minute timestamp...

I trust Aris's testing at hwbusters. His credentials in things like this (PSU issues) exceed der8auer's.

It seems I'm having a problem typing English today and had to rephrase my question.

Also it seems to me in the video he was even questioning the use of the fancy connector being displayed as a solution to the original problem while also doubting the 12v-2x6 solution.

No, which spares him the facial muscle paralysis linus is sure to get later in life.

I suppose this scenario is more specific to the 4090 and likewise high power cards.

ty_ger · Jan 5, 2024

As Der8auer has noted, the design of the connector is bad, and the design of the card is bad. Double trouble. No amount of idiot-proofing will take us back to the same level of safety that we used to have.

They should either design in a better margin of safety equivalent to what we were used to have (either by increasing the number of wires, increasing the number of connectors, increasing the size of the pins and connectors, or whatever), or go back to the 6-pin and 8-pin connectors we used to use with their existing improved margin of safety.

The entire RTX series of cards don't seem to last compared to the older GTX series of cards.

FoulOnWhite · Jan 5, 2024

2x2 stacked 8 pin connectors, cards are thick enough now to fit them

freeagent · Jan 5, 2024

My GPU has 3x 8 Pin connectors plugged into one of those new fangled connectors. Seems a bit silly..

1. Yes (there are 4080s)
2. Yes, plenty of examples on reddit.
3. No. It helped with early detection in that if the connector isn't fully seated it's more likely to just not power the gpu and trigger the user to check it out. There are still problems with the pin and socket design being insufficient, the fact that it's super easy to come unseated due to a crappy latch design, and the fact that the sockets can get bad contact if the cable doesn't protrude from the connector perfectly straight for 35+mm meaning you can't bend the cable near the connector, which is required by most builds lol. It's a bad design and they did some bandaid "fixes" that couldn't be drastic because they needed it to be backwards compatible.

It's still so bad they're planning to replace it again. I don't think multiple cables are the right answer, but as an Electrical Engineer myself, I can tell you there are considerably better designs readily available and that doesn't even go down the road of a custom redesign just for their own purposes (like this monstrosity). It's a $1500-2800 GPU. Could they not justify a better connector that is fit for purpose?

nguyen · Jan 5, 2024

Does 0.05% failure rate enough to warrant a redesign? Probably not. Highest end GPUs like 4090 and 7900XTX have 2-3% RMA rate according to Mindfactory, meanwhile 4080 only has 1% RMA rate.

Just reduce the max TDP of GPU to 450W and voila, plenty of safety headroom...

Dr. Dro · Jan 5, 2024

The connector has already been revised and fixed. This is a pointless subject.

Just for the record, AMD will use this microfit 12VHPWR/-2x6 connector in the future as well. The old EPS-type 8-pin connector will likely stick by in budget, low-consumption cards that are targeted at the mass market and older computers (as we're seeing with the RTX 4060 now), but expect the old PSU format to go the way of the dodo universally in high-end cards as power budgets increase to keep up with the demand of ever more advanced processing chips.

nguyen said:

Not even this will be necessary IMHO. The revised 2x6 connector will handle the full 600W while intentionally poorly connected.

I think CableMod's EVGA cable works for your G+. It worked fine with my 1300 G2, which is an excellent supply i'm not quite ready to part with just yet. It'll stick on my builds until it croaks.

https://www.amazon.com/dp/B0BJ2F3BPH/

This is the one I got for my 4080, it's $25, and well worth it to get rid of that fugly adapter cable. (was $80 to me thanks to tax and international shipping, but oh well woe is me).

Did you watch the video? He showed an example of one of his fail in a way that cannot be fixed by a redesign or making it more idiot-proof. The existing "fixes" do not add redundancy and cannot measure or confirm proper contact.

Arguably these are flaws that already exist in the 6- and 8-pin ATX connectors that look like the EPS plug, so I don't really see the big deal. Sure they've got a "lock" on top, then again, so does my cable...

Who said one or the other had to be correct? They both simultaneously could be.

Aris was not able to replicate 12HPWR issues at all. That doesn't mean the other outlets that could reproduce the issue were wrong. We are still seeing connectors burn up to this day, particularly if you watch any video card repair channels. That is it still occuring at any rate demonstrates it's lowered reliability as compared to the old 8 and 6 pin connectors.

Dr. Dro said:

No, they only fixed the issue of a partial insertion starting a fire. They did not fix the extremely low safety tolerances or the requirement to have a significant length of straight cable running from the connector before a bend due to the poor pin design.

I don't understand the "low safety tolerance" argument, seems like high-quality cables are more than capable of meeting the spec's physical and electrical requirements. The latch design just needs to be improved somewhat and this will not be any behind the traditional 8-pin IMO.

natr0n · Jan 5, 2024

Using dual 8 pins and will probably buy an AMD card with 8 pins. If it aint broke dont fix it.

I dont want to buy anything with that shit on it.

taka · Jan 5, 2024

All reviewes suddenly forgot about the 30 mating cycle this connector has.
Der8uer can't figure out also electric current. He sums the AMP's for pins instead of 1/R1+1/R2...1/Rn.

Can 12VHPWR issues be fixed?

Do you think dual connectors will solve the 12VHPWR connector problems with high power GPU's?

Yes - That would be fine

Yes - When in doubt just double everything to solve problems

No - Just give me more 8-pin connections

No - That's just double trouble

Don't care, I'm done with high power GPU's (less is more)

Don't care, I'm done with Nvidia

What is electricity?
