The 6 shunt resistors is actually a decent brute force solution to the 12VHPWR issues.
6 fuses on per-pin basis that prevent them going over rated max current.
That one will be even more BRUTE force.
I also saw DerBauer video, and holy shit there is card with light warning when connection is bad, but it is so easy to get even if you set cable properly, just by slightly moving straight cord.
@@DimkaTsv the whole 12vhpwr connector thing has been a disaster. Everything should be recalled. I can’t close my case without aggressively bending the 12vhpwr cable because cablemod recalled all their adapters…I just hope my card won’t catch on fire before a solution is found.
@@geesehoward7261 not a solution
@@geesehoward7261 I have a 4090 strix. Buying an even bigger case is not an option.
@@PowellCat745 You could get the 90 degree cable from Cablemod or some other manufacturer.
To answer the question about how the sense pins warn if the power is connected: they were shortened so they can only physically connect AFTER the power has physically connected. Pins of differing lengths is an obvious design because other connectors (including USB and SATA) did this decades ago, but I guess somebody was asleep at the wheel on 12VHPWR. They also failed to design a good latching system -- remember when PATA cables would also slip out randomly, and we were so happy when we got SATA with good latches?
Derbaur just made a video about the 12vhp connector. Basically saying that good quality power supplies come with 8 pin cables capable of delivering 200+ watts. Meaning you could use 3 8 pins with a good power supply and be perfectly safe even overclocked.
Corsair PSUs deliver 300W over 1x8-pin by design. I use their 12vhpwr adapter which has only 2x8-pin connectors for the Corsair PSU.
Yes, Boost Master software exists for this card but as far as I know, Splave is the only one that’s publicly cited in an article to have used such software, breaking a record with that rather than using something like a EVC2. I imagine it’s restricted to internal engineers and a select handful or less of NDA LN2 overclockers.
Until someone based and redpilled enough that doesn't give a fuck about NDAs leaks it :^)
Always look forward to these pcb tear downs
So basically you're paying 1000usd for a water block and radiator on a strix....
That isn't even that good either, the RAM gets hotter on this compared to the Strix lol
missed these videos!
Thanks for this video. Regarding the new safety features for the 12+4 pin disaster with shunts resistors I mean Galax did the same with the 4090 HOF cards. If some know more about it then correct me if I'm wrong. Again... Nice video :)
Is the 3rd chip for current measuring needed for the PCIE connection to get the full powerdraw of the card? Usually the 40 series cards have a shunt there to.
Can you possibly post a download link to the new version of memtweakit for z790? I can't find a working download at all. You have a link on an old video and it don't work for me either. It would be much appreciated. Thanks in advance
That workaround with the connector and shunt-resistor is so typical for todays mentality: We just put things out there, release them and then look if it is any good. And people on the front line (in this case ASUS) need to find a way to not have their product go up in (literally) flames.
Compare that to 20 years ago: We test things, make them as good as possible and put in a big margin for error/safety.
No 4090 has caught fire. They just melt sometimes if the contact is wrong.
Never heard of this card till now. Curiosity made me look it up.
It costs $6299 Australian Dollars. For comparison the normal Strix is ~$3400ish and the Strix OC is just under $4000.
Not sure if I should laugh or cry...
In Canada this card seems to be sold at only two retailers for $4299 or $4399, absolute madness. The cheapest price for the normal Strix is $2499 and the cheapest OC Strix is $2649. The Founders Edition is $2099.
Card prices these days are ridiculous either way.
Long shot away from EVGAs once similar priced kinpin editions. Those cards offered at least serious bios options, like running the card without any kind of limit and thermal protection.
Asus enthusiast card just exists for the looks and Richie Richs out there
Silk screen labels is nice
And public datasheets
Its not like people wouldnt figure them out if they werent open about it, and its just nice. Generates goodwill, at no real cost
Are you going to be doing Ryzen 8700G testing?

Can you do an overclock video on 2x24GB (3gb M-die) with Intel?
Has coil whine become better/less prominent with more recently produced 4090 Strix units compared to the early ones?
I have the EVA-02 4090 and the coil whine is there and can be heard through the case. But it is much better compared to the 1 year old white 4090 Strix and TUF 4090.
@@DavidRain007 i have the 4090 TUF OC and no coil whine. Am i lucky ?
Yes@@snake802002 , You definitely are lucky with TUF with no coil whine. TUFs are more prone to that because of only 18 phases compared to the 24 on the Strix.
@@DavidRain007 consider that i pay It 1500 euro with a 1050w PSU Cooler Master UNIT, and that was 2 months ago when prices were still High. In my opinion this might be the real price, of course with out coil whine 😂
Hi Buildzoid. Wondering what your thoughts are on the 12HPWR connector is as far as longevity, I've seriously been considering selling my Aorus 4090 Master because I don't think the connector is worth the trouble and I wonder if it will last as long a my 1080TI did with the 8 Pin connectors.
I posted detailed benchmarks on my channel comparing the Matrix Platinum to a TUF Gaming with AIO at multiple resolutions last week … the price premium is insane given the small increase in performance. Beautiful card though.
🥳🎉Happy New Year Buildzoid,
Just wondering if you saw Roman's new video about the 12pin Power Plug ?
Looking forward to more Rambling & learning lots more from you in 2024
I think it's not on other cards because... all the manufacturers claim user error and take your money. But somehow with the Matrix, someone thought it would be embarrassing if a good number of them burned down. (As highly probably these cards will experience a lot more power draw with their OC heavy marketing. You'd be very weird to buy it and run it stock.)
You might not realise, most 4090 models were designed/made BEFORE the 12vhpwr problems were known.
How does this differ from the TUF?
It does differ quite a lot compared to a tuf. Not so much a Strix tho
Great breakdown.
I'm so new to he channel and I'm not sure if what I'm about to ask for is available or not.
I'm also new to the hardcore stuff that are out here and recently, I found out that these stuff are actually so fun to do
It started with my 3770k & Asus Maximus V Extreme, I used to do so much things with them and thankfully, I was careful with them so I didn't break any of my system.
But the thing is that I was doing it while I'm completely ignorant, I didn't know what I was doing mostly.
So, is there any specific video where you explain how you do the overclocking stuff?
and if not, could you please do?
I would appreciate that so much
If this would overwhelm you, then please just explain where I can learn these stuff so I can do a research myself.
I know this comes with experience, but I think a little bit of information about it would help.
The main feature that made him do this video is orange square around gpu chip.
nice
Asus cards usually have a LED near the back of the connector that lights up if you try to boot the card without the power cable attached, and in this version, that LED also lights up when it detects a bad contact on one of the pins
I heard you have a b650e tachyon, no chance they sent you 2 and I could buy one from you? I’ve desperately searched for 1 1/2 years for one and still haven’t had no luck anywhere even searching different countries
PCB is good, but why is the bracket bent like that!?
The photos came from ASUS, only they would know.
Z790 nova please
Do the HOF please!
I’d call you an engineer. 0:29
Interesting but too expensive, it needs a longer warranty and to ship with a compatible air cooler
That third INE 3221 may be used to monitor +12V from the PCIe slot? Just a WAG, though.
The funny thing is, just the other day I was making a guess regarding how ATX3.x PSUs handle 12VHPWR output, and whether each pin there gets monitored separately - and if it maybe was the combination of several pins into one power plane on the CableMod adapter that ultimately causes connectors to melt.
no reason to do that AFAIK. The US5650 already does that.
guys what is the best rx 7900 xtx pcb ?
ASRock Aqua.
@@Wasmachineman it is far too expensive 900-1200 € is ok
I checked your channel never see ryzen 7800x3d oc 😊
Putting x amount of ICs + some passive components because of trashy connector, from electronic engineer perspective, is absolutely insane.
Presumably you meant 5 amps going through the six pins/shunts, one fails, so, to pick up the 5A slack, the remaining 5 pins now need to carry 6A
5A x6 = 30A which is a bit low for a 4090. Considering the cards pull 450W +
@@ActuallyHardcoreOverclocking You were talking about the shunts on the 6 (pairs?) of power pins, and making a hypothetical example to show that when one pin fails that creates additional load on the remaining pins which could push them beyond what they're rated for.

Not a fan of changes without a change in the part number. Imagine for some reason there is something really wrong with this revision of the board. How is a buyer supposed to be able to know looking at an ebay listing if that card is revision 1, 2 or whatever if there is no change at all in the part name or part number?
Also - Nvidia definitely would block a quad 8-pin card and frankly that's unlawful and harming to the consumer.
They don’t care
About the basic Problem with the 12VHP connector Roman aka der 8auer made recently 01.01.2024 a good Video. Basically comes down to a massive Drop in safetyfactor from the 8 pin to 12 pin.
Ps I'm not sure whether others would enjoy it but all this talk over the last few years about PCIe Power has me wondering if an 6/8/12 Pin Plug Spec Explanation video would be worth doing 🤷♂?
Eplaining things like why when 6pin & 8pin PCIe both have 3x 12v pins 2x 6pin does not = 2x 8pin or either not = 1x 12pin, or with all components = do they?
Plus considering people are saying space is an issue why couldn't 6pin & 8pin Plugs be made smaller using the same Wire Gauge & Pins so you could use 2x taking up a similar amount of space to 12pin?
3000€+ and no gpu bin.... LOL
Now do the Galax HoF!
all of those shunts to solve a problem caused by solution to a problem that not already didn't exist, but was already solved by 2x eps12v in terms of power and footprint. this is software engineering in hardware form.
Seems worthless considering you can get HoF instead and put your own waterblock on it. All for fraction of the price.
If I remember correctly, DerBauer did a cooling test with the Martix and it did worse than Strix in some regards 🤦
Asus Matrix - $3000
Showing it off to your friends who can't afford it - priceless.

Neat. Partner innovation compensating for shoddy rushed corrupt industry standards 👌
RTX 4090 24GB = around 80 % of them are melting their own 12-pin connectors = around 50 % have to RMA-d due to melting death of the PWR circuitry
RTX 4080 16GB = around 50 % of them are melting their own 12-pin connectors = around 25 % have to RMA-d due to melting death of the PWR circuitry

I asked this same question on Romans video and nobody has answered it so here goes.
The great 12 pin debate: EVGA 3090 Ti’s have the exact same connector and they came out in early 2022. They draw the same or more current yet those connectors don’t have problems.
Is it the 4000 series that’s flawed or is it more likely there are more of them out there so this so called problem got blown out of proportion?
What nobody talks about is if the card requires a 1000 watt power supply and someone is using a 650 watt that current limitation will cause serious heat issues in the wiring and the plug, combine that with the connector not being pushed in all the way and you will get a burned plug.
I’d say 99% of the people commenting are just regurgitating some nonsense they heard from other people. A simple hair dryer is about 1500 watts yet the wires are at best 18 gauge with it drawing 10 amps @120v AC.
12v DC @ say 10 amps is a totally different beast all together and these are simple electrical principles that have been around for 150 years.
That being said, where are all the 3090 Ti’s with burned up power plugs then? Unless there is an actual design flaw with the 4000 series then the great connector debate is just overblown internet gossip.
You have a good point about 3090 Tis. But this issue is not overblown. RUclips channels such as Northbridge is fixing 100 4090s a month apparently. That’s not overblown. It wouldn’t be overblown if they fixed 100 4090s a year.
For the hair dryer, the wires are soldered or crimped to the switch, these connections can easily handle 10A (probably at least 40, though I have seen crimp connectors inside a UPS handle more), and the wire itself will heat up inside the insulation, but the (electrical) insulation is a lot thicker than for a PC PSU wire, so it will not melt. The PSU wires have much thinner insulation around them and the weak point is the connector, which has a lot more contact resistance than the wire itself. The density is also an issue: the hair dryer has 2 wires which are pretty far from eachother, the 12V has 6 wires that are all really close, so the heat can't dissipate that well. You can see the old mini-fit connectors have power limits with adjacently loaded wires, but if you spread them out then you can push more power through it. I have not looked at the 12V high power datasheet, but I'm sure it's the same. So the connector is the weak point in the GPU system and not with a hair dryer.
This is a good point with the 3090 ti vs 4090, the power draw isn't all that much different (According to techpowerup's review of the matrix) so if it were a power issue alone then we would see a similar amount of 3090ti failures. The only thing that's obvious to me that is different is the 4090 will temporarily burst to a much higher power, but it's for such a short time that I don't see it affecting the heat much. Maybe the temporary high power will degrade the connector very slightly each time via electromigration or oxidization of the coating?
