This happened - at the time - with my GTX1660. Out of the blue, same conditions as always, no load, simply 'puff'. Fire. The retail said it was my fault somehow after I've sent photos, descriptions and offered to pay to have it sent to a technician of their choice. They basically told me to give up. And that's how I lost a new GTX 1660 after 5 months of upgrading. /rantoff :'(

This connector was supposed to be in the back of the card, so that you don't have to bend it in order to install it in the direction of the card. It should came out from the back of the case directly on the back of the card, and this would be very useful. This idea with 4090 because this card is long and larger than the board, so there was a great opportunity for this idea to be applied because the board will not remain an obstacle. sorry for my bad English.

I wonder how far into the production stage AIBs are for 4070s, 4060s and 4050s. Maybe they can still change the design, or would that be too late? After all they would have to alter the production line as well.

Another thing crossed my mind. Would a 90 adapter solve anything? It really is just moving the problem down stream when you think if it.

Sure, you can now put the side panel on but it does not eliminate this issue. If anything it adds additional points of failure. There are now two pinned connections at the ends of the 90 adapter. Furthermore, once the 90 routes this nvidia adapter down, you need to bend it down and under the gpu. Then you need to bend it sideways again to go around the motherboard.

The 90 adapter technically will shorten the distance of allowance on these bends since the adapter will now snake tighter to the underside of the gpu.

2
level 2

The correct thing to do is use a third party cable from moddiy which can bend better than the stock one nvidia send you. More money yes but the cable is only like $20.

1
level 2

Adapter wouldn't work, you don't want extra connectors between PSU and GPU.

PSU vendors supplying 2 cables, one with angled male connector (with 90 degree pins inside from factory) and one with straight connector would do the trick.

You're going to be fine, no extreme bend on the connector is the key to success and you have got enough space.

Given where the melting is occurring, combined with the fact that this connector is putting up to twice as much power through the same number of slightly smaller pins compared to the 8 pin connectors its replacing, it's more likely to be either a design flaw with the standard for this connector or connectors not manufactured fully up to spec rather than an adapter-specific issue.

Honestly whenever i do plan to upgrade from my 3080(no plan to upgrade anytime soon) I'll probably get a whole new ATX 3.0 PSU to be on the safe side. I mean not sure how widespread this issue really is but it's got me a bit spooked about using the adapters.

I wonder if this can be fixed via a software patch?

If there are sense pins, the card can obviously monitor each leg of the strand, in turn monitoring each pcie connection.

If it can monitor various data points such as voltage and current draw maybe it can detect discrepancies that arise that indicate increased draw. There undoubtedly would indications something was going wrong based on the gpus power consumption curve prior to it melting.

1
level 2

The sense pins are really really dumb. They are constantly either on or off to denote if there is something plugged in. They can't send information.

Unless they can monitor the current through each individual wire, I doubt it. a bad connection only adds a bit of voltage drop that can very well be outside the precision of the conection sensor.

I’m going to wait until ATX 3.0 PSU’s release now before biting the bullet on a 4090, and get a custom 16 to 16 pin connector from here for better flexibility:

I just bought/received my ATX 3.0 MSI MPEG A1000G PCIE-5/ATX 3.0 PSU -- it's great. I still don't understand, though, if I should be concerned since I am not using the included adaptor -- rather just plugged the 16 to 16 pin provided by my PSU to my ASUS TUF OC 4090.

3.0 PSU's are already out for sale? I am personally using Toughpower GF3 1650W Gold.

2
level 1

I don't understand why we didn't move to 24V with new connector standard for GPUs. Half of amps and quarter of power lost on connectors and cables (that would mean that 24V GPU would require quarter of connectors that current 12V one need.).

3
level 2

+24V would be possible with a two or quad rail PSU by just wiring them serially. But most modern PSUs don't use multiple 12V Rails anymore as a single rail can be implemented more efficiently and has better load balancing.

Adding a +24V Rail will not happen because the CPU is +12V and it makes sense for load balancing issues and price/size of PSUs that GPU and CPU share the same voltage. A PSU with just 24V instead of +12V would not be backwards compatible with any hardware, not even Hard drives.

If they drop backwards compatibility, they will go directly to 48V because this is already a standard for a lot of server hardware including CPU VRM, OAM Accelerator GPUs like H100 and Mi-250X as well as network equipment like switches, Nics etc.

But why not stay with +12V for a while? It is not that there are hard connector space constraints in the PCIe Format, considering how big a 4090 actually is and how little area the connector occupies. There is ample space for better connectors, nothing wrong with multiple 8P PCIe Cables and or a possible uprated 12P or 16pin variant for ATX 3.1. It is just important to ditch the stupid Micro Fit 3.0 Crimp contacts and return to the the tried and tested 4.2mm Mini-Fit which offer much higher Current rating and lower heat density than the 3,0 Connectors.

1
level 2

24V brings other issues, and inside the gpu in this case. Higher voltage mosfets have higher RdsON and switch slower so you will have more losses in them. And increasing the input voltage of a buck converter decreases its duty and adds ripple to the inductor current so you now have more losses in the inductor, too.

A higher current just needs more copper and better connections, which are more cost effective and give a better overall performance.

Had this with a 3090 back when I bought it.

The reason IMO was the contacts inside the plug had been to wide (these tubes out of metal) . So there was a small space between some of the pins and the tube in the plug. This cause a spark to appear and the plug and socket melted on the surface.

The card is still working though and never had a problem after that (new cables).

Why are they insisting one using one connector instead of splitting into say 2 cables and spreading the current\load and bending moment of the cables ? as with previous generation cards. When looking at the cable braiding it almost comes across like it's multiple grouped anyways. Medium pcb with large heat-sink

8
level 2

It simplifies the assembly and cuts on the only cost that doesn't really drop with scale; the price of assembling it and testing everything; every extra pin is an extra point of failure, every extra soldering point is another point of failure, every single additional separate component is another step in the assembly.

The better way to put the question is why are they so desperately tying to save cents on a $1600 product that they chose to run at 450 watts stock instead of 320 watts with 92% of the performance preserved and didn't leave worrying about trying to shove space-heater wattage through on AIBs selling souped up versions and overclockers accepting liability.

My dude, have you never cable managed a pc before? Literally one of the first things when cable managing gpu power cables is making a 180° harsh bend backwards to get the cables out of the way and through the chassis holes. Making a power connector that will fail catastrophically in the use case of 90% of pc builders is an epic fail. I lucked out to grab an evga 3070 last year. Normal 8 pin connectors and the last gen of THE best add in partner there ever was. Rip.

7
level 2

Here is the thing though. Cables in DIY PCs are often heavily abused. They should be designed with this in mind.

The old 8 Pins can take crazy bending. PCBs are usually hardened to withstand some level of dropping and smashing unscathed.

This adaptor on the other hand is designed with requiring care in how it's being used. That's just no bueno for the DIY market.

People should send full specifications of their new high end graphics card and ask their home insurance companies how they judge the fire safety of these things. Especially if they have any heat damage at all at the connector. Temperature measurements at the connector would be great if possble.

If you don't want to risk your insurance fee to rise, contact the local fire marshal.

Then include the responses in a class action against Nvidia.

Edit: Some people seem to not understand. If your house burns down and your insurance company finds out that high power electrical installations have not been done by a professional, they will give you the finger and let you suit yourself.

The same applies if you use stuff that has been widely known for constituting a high risk regarding fire safety.

The power cable for the 4090 is marketed as totally safe, which it is not. It is also meant for an appliance which is very much meant to be able to be left running unattended for days. Some renders take days to complete, and the 4090 is one of the most fitting products for these uses performance wise.

Then include the responses in a class action against Nvidia.

At this point there is not much you can do at those power levels.

Probably soldering 1cm thick wires directly on the PCB won't cut it either at those amps.

I think somebody will push for 24V or 30V for graphics so they can reduce the current delivered and make the VRMs work with that.

Those wires and pins are so thin. No way it can handle the wattage. Personally I wouldn't buy any card with that kind of connector until ATX 3.0 PS comes out. But even then I still wouldn't...Just doesn't look good .(Wires are way too thin to handle the wattage, especially if you are going to run it all day and night) a Triple 8 pin or Quad 8 pin would have been much much better. since you are already plugging 4 8 pins to THAT..!!!!

5
level 2

The wires are likely fine - 18AWG can do up to 10A 12V for short runs ~100W.

But when clustered together they heat each other up and any weak points massively increase resistance at those points.

2
level 2

People should collect the exact specs of wire thickness and wattage, preferably get a power draw per pin if they have the equipment to measure it. The send it to the local fire marshal and ask if it's a fire hazard.

Include the responses in a class action against Nvidia.

Also worth noting:

Unlike some other custom designs today, Gigabyte is giving you the whole 600 W maximum power limit adjustment range, the default out of the box power limit is still the same 450 W as on the Founders Edition.Oct 12, 2022

That said, we don't know if the OP cranked it up to 600w. I think 450w (out of the box on all 4090's) should be safe and generate a significantly amount less of heat and obviously current vs max power. Everyone should take a deep breath.

Little sidetracking here, but I do car audio. A 600 watt amplifier requires 8awg power wire. The 4090 recommends something like 850w. How are these pins able to deal with the heat generated? Is this why the plastic has started to melt?

2
level 2

In addition to what everyone else said, it's the connector that melted, not the wire. This connection is meant to handle 600W max across all 12 pins (so ~8A per pair of pins).

The fact that only one row of pins melted suggests to me that the connector was under sideways strain. If the pin and socket aren't making a solid connection with each other, it'll act like a thin wire and heat up.

The worrying thing is that almost all of these connectors will be under side strain in people's PCs, especially with such a massive card

2
level 2

Amps are what really matter not watts. But i think these things run off 12V like a car does so you can compare.

1
level 2
· 14 hr. ago · edited 14 hr. ago

It only requires 8awg because of the distance from the battery, 10awg easily handles 600w at shorter cable runs. With these smaller cables, you have the power split across several, so you need to add up the total cross section area to compare to a single wire. 10awg is around 5.26mm2, 8awg is around 8.37mm2, so for 6 cables to match 10awg they don't need to be more than .87mm2, and to match 8awg they'd each need to be around 1.4mm2. 16awg is 1.3mm2, so 6 pairs of that would handle only slightly less current than 8awg, and 6 pairs of 14awg would handle more. The wire itself is plenty large, and shouldn't heat up with 600w of draw.

The issue here is probably bad connection at the pins, which causes heat to build up. Each pin needs to handle like 8.5a, which isn't a huge amount, but with such small pins they need a really good connection to handle that. Bend things around or even just not fully seat it, and you'll have heat problems.

10
level 2

Because the power is distributed between all the cables. Not each pin needs 850 w. It is likely that they are still under gauged.

They're going to try to replace the card and get the borked one so they can do some analysis and see if they have a big problem on their hands.

This honestly looks like a bad pin connection due to the adapter design. They SHOULD redesign the adapter cable to have more hard material to keep the cables from bending to the point where the barrel and pin don't have a secure connection anymore.

An angled plug would do nicely.

No, you’re insurance company will ask for a list of peripherals within your personal computers and then raise for your rates if you have an RTX 5090. If you don’t disclose, then they will charge you the rate for 1x RTX 5090 for every individual in your house hold. Also, you can install the new Insurance Adjuster browser plugin that automatically forwards any and all purchases to your insurance provider for policy review! You’ll save $100 a year on your premium!

Someone have to make a better connector and cable for power hungry card, looks like those tiny pins cant take the amp

nothing to do with it, there was a contact failure resulting in excessive resistance.

a problem that could and did affect the molex mini fit 8 and 6 pins too.

Why can't they just put 3/4 8pins on the thing and just move on. They like the small pcb too much.

I'm in doubt because the connector is tiny. Not sure it can handle the ampere.

Is this the adapter for connecting to the non-ATX3.0 PSUs? Or does this issue exist with the 12V connector (for ATX3.0 PSU) as well?

6
level 2

Yes the adapter is for PSU's that are not ATX 3.0. The atx 3.0 psu's have the 12vhpwr cables and deliver the 600w of power properly but those cables should not be bent either because they are still liable for causing strain on the connector.

Aparently Nvidia reached out to op, according to a mod.

But what did the nvidia representative say?

Problem: The 12VHPWR cable is allegedly prone to heat issues if bent incorrectly. Cablemod did their own testing while developing their cables and reported that "bending the wires too close to the connector could result in some of the terminals coming loose or misaligning within the connector itself. This may lead to an uneven load across the other wires, increasing the risk of overheating damage. The risk of this is substantially higher if the bend is done horizontally in relation to the connector orientation (left to right)."

If you check their guide on this, they discourage bending the cable at all any closer than 35mm from where the cables meet the jack:

https://cablemod.com/12vhpwr/

So, obviously a power cable MUST be bent to route it from the PSU to the GPU, no matter how you orient your card and no matter where the PSU is located in whatever case you have, but let's focus on just the bend you have to make where the cable meets the GPU when oriented traditionally (horizontal, directly into the motherboard) and how that factors into the clearance that's required of your case when it comes to DEPTH. Case manufacturers will typically publish this dimension as cooler clearance.

Here's the total clearance required for several 4090s on the market when factoring the 35mm of additional cable space required to perform a bend safely without removing your side panel.

Caveat: I'm ignoring the fact that some cards have recessed power terminals. The Cablemod guidance doesn't factor the width of the jack itself, so it's a wash. I have a MSI Gaming Trio 4090, and the end of the jack is flush with the outer edge of the GPU's backplate. Other cards without recessed power terminals will actually have MORE effective depth than I'm listing below.

GPUTotal DepthGPU width
NVIDIA FE172137
MSI GAMING TRIO175140
MSI SUPRIM177142
ASUS STRIX184149
ASUS TUF195160

GIGABYTE WINDFORCE185150
GIGABYTE AORUS198163
ZOTAC AIRO185150
ZOTAC TRINITY200165

The required clearance ranges from 172mm - 201mm.

Now, let's look at some cases

FRACTAL MESHIFY 2185
NZXT H7 FLOW185
FRACTAL DEFINE 7185
PHANTEkS P600S190

So, as you can see, a lot of these cases, even some of the big boys that you'd just assume could easily fit a 4090, actually can't fit many of the AIBs horizontally without bending the 12VHPWR tighter than Cablemod is stating is reliable. I keep seeing posts with people showing off their new 4090s with the 12VHPWR adapters pressed up against the glass, then you see posts about these same cables melting.

I'm sitting here with my MSI Gaming Trio in my Lian Li O11D with the glass off. There are 2 things that can save us: (1) a Right Angle adapter that's compatible with all 4090s, while still not protruding more than about 20mm. The adapter Cablemod is about to release tacks on an additional 23mm, and will not fit on a lot of these 4090s that have their 12VHPWR terminals recessed into the radiator. NVIDIA really should have provided a RA adapter from day 1. (2) Case manufacturers need to start making deeper cases.
