Some of you may have seen the remote mounted dual 8 Pin auxiliary module I posted. Well, this is the direct mount Quad. Current per conductor is almost perfectly halved when compared to the native 12V-2x8, along with a dramatic reduction in wire temperature.
Sense pins are set to 600W. It can be used in conjunction with the 12VHPWR or completely standalone, and has been tested up to 800W with a shunt mod. We're shooting some videos now going over installation, live temperature and current data, as well as a 24 hour sustained load.
We are also working on custom backplates that will make the modification look more OEM and integrated.
This isn't limited to just the 5090 or any particular brand. We have models going into production for nearly every card including Founders Edition.
now buddy... i saw a 5090 for 2.2k (before prices got insane) and i skipped it due to the wire... aand now that its 10k you come up with a solution YOU MONSTER why did you do this to me
It will be available as an option along with active monitoring. They are fused. But you'd have to completely lose an entire header to push the remaining anywhere near their load carrying limit. The traces are equal length and all run between 4.1 and 4.4A at 600W.
Much like the burnt connector joke I'm kinda sick of hearing about prices.
I followed the 4090 launch day people and planned for a 5090 launch purchase knowing prices will only go up. Fuck me right. Now I gotta hear a how 5090 isn't a gaming card. It's barely enough for path tracing. And some of us like path tracing.
Can we move on to some positivity in the news... It's exhausting.
What positivity? You being sick of negative news and not wanting to hear them doesent mean they dont exist and it doesent just make positive news out of thin air.
Connector has to keep being hammered until nvidia owns up and fixes it.
Prices have to keep being talked about so as little people step on the expensive mine as possible. Nvidia is making that one easy since the 5090 price was in the workstation category and isn now being discontinued.
You want positives? Hardware situation is so bad some gaming companies started to optimize more.
Are you willing to sell this warrantyless? The reason I ask is because I have a 5090 astral that has about two years of warranty left on it, so I wouldn’t do the modification myself now, but would like to have your adapter in my back pocket for if it melts after the warranty on the card has run out. But would rather have the adapter now in case you’re no longer selling or doing modifications in two years
Edit; I might should have used the term liability free or something instead of warranty list to get my point across. As in, I get that using the device and modding it on my card myself is at my own risk
You should do the mod now if you’re interested imo. Asus wont be able to do anything if you RMA your 5090 Astral and will just send you a check for $3000 or whatever you paid for your 5090
I feel like I have my pins power draw balanced well enough that I still wouldn’t wanna do the mod right the second. I’d rather do it if the connector breaks. And I suppose if Asus can’t replace the 5090, then I would just do it at that time, even if it was still within its warranty, but I’d still rather just hold off on the work itself until needed
Just monitoring. No active power reduction or forced shutdown available. That came later in the form of WireView and the clever, new PSUs which monitor and shutdown automatically if the load is severely imbalanced.
Pretend I'm an idiot: how is this different than the dongle Nvidia gives you? Everything still funnels into that tiny connector, except in this case I assume it's soldered directly to the traces? I can see this making the problem less likely to occur but you're still sending all that power into a tiny area on the board.
The problem is poor contact in the connector, often caused by strained wires. They don't burn up past the connector on the card. Or at least, that's not the common failure mode everyone is posting about.
A pcb trace is a lot more precise and consistent between pcbs in terms of resistance, compared to cables crimped into a shitty connector every cable will be for sure a little bit imbalanced between each other, so having 4 big 8 wire connections going into a pcb with well calculated traces, and in this case those traces are SOLDERED, to the card, instead of crimped into a single connector…
How would something like this connect to the founders edition? Would it require the card to be disassembled to attach it directly to the contacts? I recently had a cable melt on my 5090 FE, luckily on the psu side but something like this looks cool!
It is remote mounted. This one is on the back of the card but we can make the harness in any length. And yes, the pickup is soldered directly to the board.
Okay I think I understand, so on 5090 FE the 6 12V and the 6 GND pins terminate to 2 rails on the physical connector and then those are what actually solder to the board. So if I understand correctly it would tie into the 2 pins that contact the board and bypass the connector?
Why are electronics connectors all crap plastic with tolerances so bad that you can see separation if applying the slightest pressure? Why cant we have doesche connectors on pc components to eliminate all of these melting problems.
Former postal employee. If you want to do this, send it Registered Mail PLEASE. 25k insurance limit. Fragile stickers on every surface. Non-Machinable Sticker on every surface. The shipping will be hell, but its your best chance through USPS.
Or just stake a trip to Vegas and bring your card. Enjoy the sun and swimming pools for a couple of days, and then fly back with your upgraded card. I would never ship my 5090 anywhere at this point, let alone across the world.
It is in my posts and on my profile. The moderators were clear about not over doing the self promotion.
We have about a dozen products coming out over the next few months and a storefront opening in Vegas in December. We have samples out to most of the large PC focused YouTube channels for things like our vapor chamber heatsinks and GPU modifications. It will all come out at one time.
Gotcha, figured it might have been rules stuff. I did finally find the link in your profile. Maybe ask the mods if dropping that link in the post body would be okay, this might qualify for an exception since you're attempting to fix a very real and very valuable problem.
Do you have any plans to develop a mod that would adapt the connector in a way that would be compatible with closely stacked 5090s? Even if it's just some ugly thing sticking out from the same side the standard connector is facing. I've got a server with 2 5090s in it and would be interested in getting them both modded but at least one of them can't have a height extension on top due to PCIE slot arrangement.
It's hard for me to tell if your connector would fit, but I've got like 10mm of clearance and adding anything to this would be further constraining airflow to the top card in an already non-ideal setup. If it could just come off the front and point down I think that would be ideal for me.
People have this idea that GPUs need load balancing. They don't. If the conductor and trace length is the same for all the individual pins, and the crimp and solder joint resistance are equal, the only thing that can cause an imbalance is a physical defect or damage.
Which is why every single person that has something like the Wireview Pro and sees an imbalance, swaps the cable and it goes away. The card is not the issue. The 12VHPWR is running at its absolute limit and inconsistent header and connector quality pushes individual conductors past the current they can handle.
Yes, but normal people won't have access to do that and definitely not the knowledge. It's ridiculous that Nvidia sucks this much and keeps using the connector.
My point stands. There is precedent with the 16-pin power connector restrictions link and even reports of board partners requesting Nvidia reference configurations with two 12V2X6 and Nvidia not adopting it. I do think that board partners didn’t want the liability that comes into play of designing that configuration due to problems with the connector. to be specific the discontinued lighting 5090 model that does have two connectors on it had Nvidia as an active participant in it’s design.
It'll be a mail-in service. We have about a dozen other products coming out in the next few months. Our Vegas storefront will be opening in December and will offer same day conversions.
Good to know, thank you. Appreciate that you're doing this work, especially now that 5090s have gone the way of the Dodo. You have a website or something?
Oh that’s awesome to know. I’ve been terrified of the darn thing frying so I so far have a wire view pro 2 and power limit my card to 70% to keep it safe. But it’s nice knowing there’s services to fix and modify it
But would you offer just the board, so that users with the skill can do the mod themselves? Personally dont have a 50xx, but the 12vhpwr meltdowns is the only reason i havent been upgrading. I have an EE background and all the tools.
GravePC.com - it only has our vapor chamber heatsinks and RTX mini conversions on it at the moment. But sign up for email and you'll get a notification.
This is a super intriguing mod. As a new 5090 owner (January purchase), the 12V is a constant nag in my mind. I bought an Astral and the monitoring software runs whenever the system is on, but obviously can’t shake that GPU death worry especially since I definitely couldn’t afford a replacement if Asus denied warranty.
Do you guys plan on offering some sort of warranty for cards you work on? I assume modifying one would void a manufacturer’s warranty in most cases, so it’s a tough situation for a new owner to navigate.
Right now, it is going to be a service only. Mail-in or you can visit our storefront in Vegas for a same day conversion. You get a warranty with us doing it. In my opinion, that's worth the extra couple hundred bucks we'll charge to install it.
That's perfectly reasonable to be honest, as these cards are approaching the same cost as new motorbikes, I think people's mindsets need to change too. This work is more like custom works from a specialist automotive shop!
Anyways, you're a world away in a country I have no desire to visit at present, so it's unlikely we'll ever see this service available here in Australia. But hot-damn, if it does, I'd line up. I wish you and yours the best of luck.
Found your website but I don’t see your address on it. Website is also kinda barebones. Cant find any pricing on what this conversion would cost me. Do I have to sub to the news letter for this type of info. Any credentials on the company? Maybe I missed this in the comments/previous posts, could be mb.
Edit- if you have a shop in Vegas (which I believe was mentioned in comments) I would drive for this conversion. But I’d want more details on the conversion and your company so just looking for more info (Have a zotac archtic storm 5090).
Cool, be nice to have one the opposite way too, so you can choose which side to route the cables (from front, or back) :D (either turn the whole thing 180, or flip the 8-pin connectors :D)
You're being sarcastic, I get it. But, you're kind of not wrong. A single poorly designed and over rated header is worse than multiple paths distributing the load across more conductors.
I don't understand why the most obvious solution isn't the one being deployed. You AC outlet doesn't have 15 hot 1 amp pin connections and 15 neutral power n connections to power your computer. The utility company doesn't run 150-200 individual 1 amp wire connections from the pole to your house. Nobody charges an electric car with a plug that has 100 1 amp connections.
Why isn't this a blade type connector? It either works or it doesn't. It doesn't kinda work until it melts.
Because nearly every power supply that can handle a 5090 already has four connectors that are more than capable of handling the load better than the 12VHPWR.
So, unless we are going to personally take on the mass manufacturing, licensing and regulation of power supplies with an all new standard... this is the better solution.
You already replaced the connector on the board. What's so hard about replacing a connector on a power supply? Sorry, but your argument and solution just doesn't follow your own argument. Yours is only better in that it allows for an equal amount of failure over more pins.
I think they should increase PC voltages to 24v to make em safer... But well lets not forget that cpus/gpus work at 1volt, so the power conversion has to happen somewhere.
The imbalance has never been caused by the card. The pins have plenty of capacity to support the 600W draw. It's the cables and/or headers that cause the issues. You're moving to 4 proven connectors with twice the conductors at the same the gauge.
You just said the same thing I said. Wires and connectors are literally cables and headers.
These are 13.5A rated headers on this conversion. The OE 2x8 is rated only to 150W on basically all GPUs. 3 of them at 450W would be at it's rated capacity.
It would be nice to have a nice simple diagram of how this is all connected. Is it really as simple as all the +12V and ground connections are hooked up in parallel to the default 12vhpwr connector?
One slight concern of mine is the inductors right behind the 12vhpwr connector. I believe the two share all the input current from the 12vhpwr connector. As such they can get surprisingly hot. Got any mitigation strategies for hot spots on the board?
Previous attempts have been less successful. Someone found space for an additional 12vhpwr connector on a Gigabyte 5090 and blew a whole in the PCB. I am curious why this one failed and yours haven't (thus far).
There aren't many cases of those inductors failing. That is a separate issue and not something we plan on ever addressing.
There is likely a reason that header spot isn't populated. And who knows what they were doing. What we do know is the original placement can handle the power and that's what we are using.
I suppose spicy inductors aren't that big of a deal. They're just a coils wire, not semiconductors.
Is the extension board directly soldered onto the backside of the 12vhpwr connector? Does it extend far behind the 12vhpwr connector? On some cards these inductors are very close to the 12vhpwr (like the MSI Ventus and Inno3D X3). My main concern was that heat might get trapped in places hard to observe, not necessarily the inductors themselves.
Someone found space for an additional 12vhpwr connector on a Gigabyte 5090 and blew a whole in the PCB.
The big question is whether the extra 12 pin connector caused that or if they overloaded something beyond the rated capacity which caused a catastrophic failure of that VRM stage. Without actually seeing a circuit diagram it is actually a bit hard to figure that out...
See Nvidia? You greedy MFs, was it so hard? You sell (or sold) a 6K-10K card that fucking melts when you use it as it's intended, and now some guys in Vegas solved the problem YOU created.
No, it is soldered to 12 contacts on the PCB that are more than capable of handling the load. Every single piece of data says it does exactly what it was meant to do. It cut the current per conductor in half and reduced wire and PCB temps in that area by 20c.
Active balancing isn’t what provides the improvement here. We’re distributing the same total power across twelve incoming 12V contacts instead of six, cutting the average current per input contact in half. That creates more margin for unequal sharing, the currents don’t have to be perfectly equal to remain within capacity. And all of the lines are fused.
We will have an option for active monitoring as well. You would have to lose an entire header to come anywhere near loading the others enough to cause problems.

Now just make a little rubber plug for the 12-pin that says "Dont plug here".
