Proposed new Power Connector

[AusWolf]

One compact plug instead of two huge plugs is a progress and I like progress. If this compact plug used robust tabs instead of tiny pins, if would be great.

It's not progress if it burns up.

I do not follow the names either, I just call it Nvidia 12 pin.

But they are different standards as far as I know, so you have to follow the names.

If you use damaged or badly made connector and push a lot of power through it.

The second version just does not tolerate being partially unplugged, the underlying tech is still the same.

Have you assessed that the reports came from users of damaged or badly made connectors? What is a "badly made connector"?

I recommend this thread, and this post specifically:

Unofficial 12V-2x6V Power Connector Melts NVIDIA GeForce RTX 5090

They uses 110V/220V, that's different. 5090 runs on 12V 50A, and the working temperature >60C. So 1x 6AWG, or 2x 10AWG Give it some safe room and the solution could be just scale up the original 6 pin design with 10 AWG wires and connectors Or maybe we shouldn't have 600 W GPUs? I know...

I still can't be asked to follow up on it. Sorry. I'm happy with my 8-pins, leave me be. "If it's not broken, don't fix it" is my motto.

I'm actually all for solid connectors that you have to attach some type of pigtail to like a terminal block.

If you smoke it, you screwed up.

There is nobody who has really given me a real reason why we ever had to abandon pcie 8 pin.

The supposed reason was... eurhm... power increases? It 'didn't look nice' to have 4x 8 pin next to each other? (Makes you wonder what magic happens in people's heads when there are instead 3 of those plugs... which has been the case for years and still is)

There is no size constraint on GPUs to not just have a 4th plug on them. Heck, get creative, stack two on top of each other and side by side, you'll still not exceed GPU height and you'll be using what, 2cm width over 12x6?

Its a complete clusterfuck that gets us nowhere, except into buying new equipment, adapters, and applying workarounds to make sure said new equipment keeps working properly. Do anything wrong? User error!

Keep it Stupid Simple.

A massive 4 slot cooler that is near the limit of length, and they use a daft flimsy little 12 pin connector.

True, there is enough space on the large cards for four 8 pin connectors and in most PC cases enough space to run a forearm thick bundle of wires to the heater.

Apart from the tiny pins, manufacturers refusing to make high quality components and users refusing not to abuse the cables, everything would be fine and people could use one or two elegant small connectors to power their heater cards.

What does it matter if there is a thick cable in your rig to power your near 1kw GPU, it doesn't. If you want your rig to look elegant inside, don't buy a near 1kw GPU, simple.

I am not sure that two 8-pin connectors won't be sufficient to withstand up to 1000W power draw?
Are there tests which actually have shown that there was a need for a new connector?

If so, there are two options:
1. Set an upper TDP limit of 250W - I'm looking at you greedy black leather
2. Design a new connector with very thick pins, in order to be able to carry that current.

I think we should stick to 375 W max on a single GPU. 75 W from the slot, plus 2x 150 W from two 8-pins is more than adequate. There's no need to reinvent the wheel.

375W is already a lot. An old-style soldering iron for electronics is 30 W. This is enough power to melt solder and plastic. If anything, the comfort you have in the trusty 150W 8-pin connector proves that high-power, high-current connectors and cables can work very well if properly engineered.

Interesting ideas but do some believe nv even pays attention to these ideas?

honestly, no sane company would. The internet is known to be full of people who present as engineers but should never be trusted to act as one.
