12VHPWR has a higher number of failures in a single gen than 6/8 pin does in 17 years

[evernessince]

The gold nugget of this video though is this chart illustrating the total number of people who experiences issues with 6/8 pin vs 12VHPWR:

I'm surprised GN didn't do more to illustrate why it's extremely bad that 12VHPWR already has a higher total number of failure instances. 6 / 8 pin has been around for 17 years while 12VHPWR has only been around for 1 GPU generation and yet the number of failures already exceeds that of 6/8-pin. If one were to extrapolate this data into a failure rate, 12VHPWR would be several magnitudes worse.

That's before you even consider that the question is narrowly enough worded so as to exclude 12V2X6 issues. Even if we assume that they reduce the failure rate of the connector by ensuring it has to be properly mated, the failure rate is still not nearly as good as the 6/8-pin due to the lower safety tolerances and the 25cm straight cable requirement of the specs.

IMO this kind of increase in failure rate due to a power connector is absolutely unacceptable. More than 17 years worth of failures now happen in a single year thanks to this new connector. IMO GN did not go nearly far enough in pushing from improvements or replacements to the connector.

I'm sure it happens, but I've never seen a case of catastrophic failure for either connector that wasn't related to user error in some way.

For sure there are user failures in both instances but the fact would remain that one connector is vastly more resistant to user error while the other is not. I still see a lot of people complaining about the lack of clicking in their 12VHPWR / 12V2X6 connector and the mating force required to correctly install the new connector, which has just been an issue since day one and is bad design.

 

[DirtyDingusMcgee]

Personally, I'd like to see pigtails on the cards themselves, and use big fat conductors and connectors. Something like this

but I doubt that is going to happen. A lot of us use power supplies you could weld with, and tiny wires for the conductors (ever seen welding leads....they aren't tiny).

It is bound to cause problems at some point. You are probably right to seek a better design.

I see you are referring to the exhaustive study and 1 hr 12 minute video from Gamer’s Nexus?

The majority of problems stemmed from angled connectors, and of those the highest number were from 2 brands. I think also the problems were nearly all from aftermarket connectors, not ones that actually came with ATX-compliant PSU’s.

It’s not so much a big deal.

The video was done in collaboration with industry experts and sources and it was also fact checked by experts as well. I'm saying this because you appear to be sarcastic.

Well yes "you think", because nothing of the sort is stated in the video. Seems rather hypocritical to rebut the lengths GN goes to provide objective information but then having nothing to counter it except personal opinion and then coming to a conclusion that it isn't an issue based merely on that.

You seem to have a difficult time understanding percentages. Maybe read it again slower this time.

It really is not that hard to click it into place.. you just push until you hear the click, not until you hear your PCB snap. Maybe it is an issue with the cable itself? Maybe A-Brand PSU maker has a better cable than B brand?

Just grasping at straws here.

Not gonna lie, it is nicer to deal and route 1 cable instead of 2 or 3.

in terms of same power draw specs, its 1 cable vs 4. I wonder what failure rate of 2x6 pin if you pulled 300watts through each to match that 12pin.

A connector that does not actually feel smaller than a PCIe 8-pin would have made that easier. I remember being shocked by how little it is, for something supposed to carry 12V/600W, hanging off a beefy cable.

It is not as if people don't still have to deal with huge legacy connectors elsewhere, despite attempts like ATX12VO.

Indeed..

But as long as it is clicked into place it should be fine. Running my card all out and the cable and connector are fine temperature wise.

I don't know.. maybe I am just good with my hands? Even my first try plugging it in was not a problem at all, heard the click and I was set. Once its in, you can pull on it, do whatever.. within reason.

Or just buy sub 300W GPU, cable will never melt, problem solved.

But then there would be nothing to rage about

You can see on the Nvidia reddit quite a few people are pointing out that they don't get any click at all. One of the complaints were that people weren't getting the clicking. Combine that with some cards obscuring the card side connector and it was not a good recipie.

Maybe it is an issue with the cable itself? Maybe A-Brand PSU maker has a better cable than B brand?

Lack of safety tolerances and lack of an actual enforcement mechanism to ensure connectors meet the standard are two factors cited in the video.

If the cable were the issue, I'd assume it would have manifested by now. After all you had people professionally testing to see if they can reproduce this issue and the cable was one of the variables controlled. They tried different adapters, PSU, insertion methods, ect and the only thing that made the issue reproducible was not fully slotting the connector and bending the wires to the side (as if you had your PC side panel on).

Just grasping at straws here.

It could help airflow too. IMO though not worth additional failures. I'd much prefer something like what ASUS showed with the power connector on the mobo. Zero cables in that instance.

cable will never melt

It'll still be both fugly and unnecessary because SURPRISE, a single 8-pin is more than fine for sub-300 W GPUs. Of course if we're talking quality plugs and quality PSUs in general.

Cotton candy is a better engineer than those invented 12VHPWR.

Where are those 300W GPU with single 8pin? do you know what you are talking about?

You assume that which does not exist. I’m not being sarcastic at all. You seem to be worked up. You ok?

Nothing of the sort, huh? The primary focus of rhe video was with angled connectors that aren’t OEM. You seem worked up. I’ll ask again…you ok? Is this personal for you?

Most of the problem was the CableMod cables.
