Bump

@@Frostbite1090 thanks. Jay didn't provide much details but I believe it was same issue. Ours case was ZOTAC GAMING GeForce RTX 4090 AMP Extreme AIRO on ASRock X670E Steel Legend. For some reason it didn't work but later worked, got it settled within 24 hours and managed to work perfectly for the RTX 4090 launch event.

@@PlayMates_ Thanks.

We hope he sees this!

Corsair just posted a statement

Corsair posted an apology for disrespectful behavior and language but they did not admit fault or give a technical answer.

@@johnhowarth7216 Nope GN is right, they also have the specs right from Nvidia. In the 4x8-Pin Adapter there is an extra IC, that checks EACH 8-Pin, if it is plugged in and then sends the right signal to the sense-pins.

@@johnhowarth7216 nope, If you had watched GN provide the source for their claims (Nvidia) so it looks like Corsair don't know squat.

@@johnhowarth7216 Confused too. But my understanding is that anything less than 4 cables can only draw 600w as where all 4 cables draw 630w which good for overclocking. Also I did an analysis on spikes GN did earlier and the 40% transient spikes on a 450w power source will go over 600w.

if you're in there bending your GPU PSU cable a LOT... you got bigger problems you caused lol...

@@wojtek-33 hes talking about over time reason why most cables have a bend rating

As history has proven again Jay has small knowledge on electronics. 100% that is not a solid core cable, yes he miss spoke again...

We are going to start to need new cable tech soon, which is kinda gross. 60FPS at 4K is fine, stop it!!! but...

@@warpedphreak don’t forget, as a reviewer, Jay is regularly swapping components. Regularly unplugging power cables. Yes, in a personal rig, you shouldn’t have that problem.

My PSU unit does have these kind of cables? Corsair RM850x. so could i power a 4090 with it? it has 3 double cables... im not sure how it really works

Imagine. My PSU only has one 6+2pin and two 6 pin. To use squid adapter I would need four 8 pin connections. #1 is solved immediately. #2: A two-6 pin to 8 pin adapter. #3: Two molex to 6 pin x2 then a two-6 pin to 8 pin. #4: same as #3. That's a total of 8 adapters. 😂

@@MrMirukou You can power it with the RM850x. Tech Yes City did all of his day one 4090 reviews on that powersupply. As for the wiring of the psu, I can't say how he had it wired.

@@MrMirukou Cables with two 8-pin connectors only deliver the same amount of power as a single 8-pin cable, which is 150W, IIRC. I would avoid using too many of those.

@@ShmeeGrim That is simply not true. The PCIe 8 pin standard is essentially implicit communication. It says that if all 8 pins are connected correctly, the device (GPU) can draw 150W. Even if you make a cable and PSU capable of supplying 1.21 jigawatts, the device (GPU) has no way to know that, so will only ever draw upto 150W sustained per 8 pin connector. Corsair's cables can sustain 300W. But that will only be utilised if provided over two 8 pin PCIe connections, so their cables terminate with those two 8 pin PCIe connections. At the other end, there's an 8 pin connection to the PSU. That connector IS NOT an 8 pin PCIe connector. It's a connector bespoke to the PSU manufacturer. It can output up to 300W. It only works correctly on the manufacturer's PSU, as the the pinout is often not the same. (NEVER use a modular cable from a different manufacturer, unless you fancy risking connecting a ground pin on your GPU to a 12V pin on your PSU.) So, each connector on the Corsair PSU absolutely CAN deliver up to 300W, and using the twin 8 pin PCIe connectors at the other end CAN allow 300W to be drawn. The nVidia adaptor needs four 8 pin PCIe connections as each such CONNECTOR only guarantees 150W. You could be attaching for separate 150W PSUs. You could be attaching a nuclear power station over solid copper bars. nVidia can't tell, so they will only ever draw 150W per 8 pin PCIe connector Corsair have made a cable for THEIR PSUs. They wire the 12+4 pin connector to tell the GPU that 600W is available. They make the gauge of the cabling capable of delivering that. They make the PSU end of the cable connect to TWO of their 300W PSU outputs. Thus, their single cable CAN sustain 600W from their PSUs. Note that if you plugged in only One connection at the PSU end, only one of the two sense wires would be grounded (the other would be left "open"), and the GPU would be able to tell. Thus, the GPU would only be "allowed" to draw 300W from that connector. An 850W Corsair PSU absolutely CAN deliver 600W over either two of corsair's twin headed PCIe cables, or one of their 12+4 pin HPWR cables. As that leaves only 250W for everything else, including transients, I'm not sure I'd want to. I'd rather ensure the GPU be limited to 450W to leave enough capacity for your other components.

No, it'd be fine. The 16 pin cable is essentially just two 8 pin cables combined.

The original Corsair post was incorrect, but it wasn't incorrect about their own product it was incorrect about nvidia's product. It was simply a misunderstanding and they have apologized. It had nothing to do with whether or not the Corsair product is technically good. There is no difference in power between using the Nvidia adapter and corsairs, other than nvidia's adapter will produce a messy bunch of cables which might cause other issues. The IC on nvidia's adapter is designed to count how many cables are connected to it. Corsair's cable does not need to count how many cables are connected to it because there is only one configuration option and that is the plug both cables into your power supply. No need for an IC when the pins will always both be connected to ground.

@@metaleggman18 an eight pin cable has three lanes of 9 amps each, for a max power of around 324 watts, however the spec limits it to 150 watt (this difference is why you see pigtails). The 16 pin cable has 6 lanes of 8.5 amps each, for 612 watts rated power, or limited to 600w by the spec. So, yes, it is exactly like two 8 pin connectors, although it has more 12v wires than two 8 pins, and runs much closer to the spec of the underlying components, in theory.

You can push all the frames at 4k you want on a 1080p 60hz monitor and you probably won’t notice a difference between that and 1080p 60fps. So if you have a lower end monitor your GPU won’t need to work as hard to run the resolution and frames that are optimal for you. That’s why you should always match your GPU to the monitor you have or plan to have in the near future. It doesn’t make sense to run a 40 series card, or a 70 series card or a 6800xt/6900xt for 1080p gaming because you aren’t utilizing the performance you paid for. As soon as you step up to 1440p or 4k and high refresh rate (120+ hz) it starts to make sense to go with a higher end GPU, but honestly no one needs a 4090, even for 4k gaming. It sits in a weird space where it’s too expensive and overkill for general consumers, and not powerful enough for professional use where Quattro’s dominate the space.

@@abnormallynormal8823 "It doesn’t make sense to run a 40 series card, or a 70 series card or a 6800xt/6900xt for 1080p gaming because you aren’t utilizing the performance you paid for." What? You can't just default assume you aren't utilizing the performance. It depends on the game, and settings. Lower refresh rate and resolution are always an opportunity to increase graphics settings. Now, if you've already maxed them out and still aren't anywhere near 100% GPU usage (assuming appropriately powerful CPU) then yes, your card's potential is kinda wasting. But unless that's the case in all games you play or might wanna play, you can't really say you've overpaid for the GPU. That's obviously not touching the possibility that you might also need/want the card's performance for professional use (like rendering, AI and other compute stuff) where your monitor doesn't matter. But that's another story

Can't wait to see pictures of people molex>6pin>8pin>12 pin. And having two speaker wires coming out from the side band, grounding into the case with techscrews (ground IS ground ¯\_(ツ)_/¯ ) ^not unlike shi**y audio setups in cars :))

@@IcecalGamer as long as they include adapter cables with the cards, I don't think we're going to see much of that. I hope I'm right. Just for the sake of people's homes and their neighbors.

To be fair, Jay isn't always right, no harm in double checking what he says. Literally last video he said these are PCIE 5.0 cards when they're 4.0. At best he meant it figuratively, but he didn't present it as such.

@@blarghmcblarghson1903 he did? Weird. It's an issue for me. I use the additional slot for a mellanox (I won't call them Nvidia) infiniband card for my storage network, so being able to use the GPU at 8x without a performance hit is a feature I want.

A 4to1 adapter cable (and 2to1 too) will still need an IC to drive the two sense pins. As it needs to count how many cables are connected on the ATX 2.0 end, as any three out of four should produce the same sense signal because you cannot rely on users populating then in the order prescribed by the engineer. I didn't see an IC on the Corsair cable and because it's got two inputs I half expect it to incorrectly report the higher mode if one one cable is connected to the wrong input.

@@morganlimes cool

Did same thing for my 3080 FE, definitely an awesome perk, and a very well made cable to boot. My only thing is did you notice that the 12 pin connector doesn't seem to look completely seated?

Can I get this cable with the 2 8-pina for the 4090? Or do I need a custom cable that has 4?

I'm sure Dawid will have video of himself doing this unintentionally before the month is out.

@@Eric_Fate Oh god, here we go!

I'm looking forward to someone using molex to 8 pin to 12 pin. More adapters is more better, right? Right!!

Few weeks and ebay will have molex to 12VHPWR with these two ground wires installed.

I'm not sure you would. The issue is the connectors, not the wires. Three pairs of 18 AWG wire won't melt at 450 watts, but the connectors might.

Long cabels with a lot of connectors are usually way worse than shorter cabels without them.

Fortunately these products have specs that are available online, and have actually been tested for their power rating. Microfit connections from molex are almost as good in terms of power delivery as mini fit Junior (with a rating of 8.6Amp versus 9 on the larger connector). When you consider that the standard would normally use pigtails on 8 pin connectors, four 8 pin connectors would use 6 positive wires and 6 ground for 600 watt, and a single 16 pin connector would use 6 and 6 as well.

AWG 18 (0.75mm²) cable is the most common across power supplies and can easy carry 12 amps (1440 watts @ 120V). In Jayz video it looks that AWG 16 (1mm²) may now be the standard being moved to, easily carrying 15 amps (1800 watts @ 120V). So these cards risking igniting their "own" cords is not a problem.

@@hexdator2934 good point. the reason I didn't bother to talk about wire gauge is that the limiting factor is the pins in the connector at the lengths used in a PC.

@@edwardallenthree You went to an even greater level of detail......👍I was replying to OP..

450

and that Corsair said Steve was full of shit lol, which he promptly proved them wrong.

Can you link that video?

yeah I wanted to see Jay try to pull 600 with that setup

Ya but 300watts will give you 90-95 percent of your performance. Using the full power on 4090s isn't worth the marginal performance gain

I'm waiting for the new AMD RX7000 series... Display port 2.1 confirmed...

The mid range cards are laughable, better off skipping this gen or going Amd

i wouldn't rush to buy midrange yet there are some other cards coming that 1. might have display port 2.0, 2. actually support PCIe 5.0 and 3. not need 450 watts for this level of performance.

Why not buy the bow cheaper to get used/maybe new 3090 or 6950xt since they are around 1000 now lol

Why do you need DP2.0? Is 8K 60Hz/4K 120Hz not enough for you?

They issued an apology already. Apparently the comment was made independently by one of their employees.

typical back peddling when found out.

Isnt it always the case when an employee fucks up but its the whole company when an employee does something extraordinarily good? 😏

well no surprise there. 30 series behave the same way :p And AMD too actually. They don't show the total board power so they appear to be more efficient, but they also benefit from lower power limits in the same way with a really minimal hit in performance. those last FPS are a b**** to get for the benchmarks.

Yeah most psu can do 1 8 pin psu to 2 x 8pin pcie pigtail

The reason for 4 8-pin adaptor is simply because each PCIE 8-pin is rated at 150W (it is the standard), so you need 4 of those to get up to 600W. You don't design 2 8-pin adaptor and rated it for 600W because it will be a fire hazard. The adaptor itself can sense how many cables are attached to the adaptor, so if you only attach 3, it will tell the GPU that the max power is 450W. If you use Corsair PSU using the adaptor, you still need to connect to all 4 to get 600W max. One of the potential problem in the future is that if people ended up breaking or losing their adaptor (maybe buy a 2nd hand 4090 card and it doesn't came with the adaptor), they might think to simply trying to purchase the cheapest adaptor and those adaptor is not a smart one, it could end up with the GPU trying to pull 600W from 1 8-pin.

@@RurouTube While the PCIe spec may say 150W per 8-pin ATX, in reality the three positive wires and Molex Mini-Fit Jr. pins are capable of much more than that if properly spec'd. Roughly 108w per pin, or 300W+ per 8-pin connector. Since Corsair specs the cable and the power supply, one must assume they know what their pins and wires are rated for and thus this is a 100% safe and compliant use case at 600w.

@@bradley3549 What I wrote is not about whether Corsair can do 600W safely from a single 8pin but more about the reasoning why Nvidia included this 4x8pin adaptor. It is not about single rail or multi rails, it is simply because of the spec. The spec for 8pin is 150W. You can't expect every single PSU on earth to safely do what Corsair PSU or its cable can. Edit: this is just from safety issue. There is also from function stand point where while PSU at this category should be able to supply more than 150W from a single 8pin, there might be edge cases where it can't. Also just having 2x8pin might ended up making people have a false sense of security thinking that their PSU with 2x8pin should be able to handle 4090 when in reality it can't.

@@RurouTube spot on.. and some PSUs really put the bare minimum gauge to get 150W. through a PCIE cable. The cable needs to follow the specifications anyway. you don't deviate from rules just because "it should be alriiiight" ^^

Those 90's ads gives me nostalgic

I miss the good ole days

Good old Lew unboxing stuff for us on 4 hours of sleep 😴

This is false lol.. do the same test he is doing and you can see the wattage being supplied. I have a 1000 Corsair and this cable and I’ve had my strix card up to 527 watts. So it is definitely over 450.. maybe that’s changed I guess but as of now it isn’t true

@@klipschorny yes it worked fine. I have a RM850X

Wait what? This cable will only draw 600w if you have Rmx1200w supply or above. Anything less, it defaults to 450w. But people are ignorant, so they deserve to get scammed.😂🤣😂🤣

@@csguak why the fuck do you need 600 watts of juice to power a graphics card? Are you building a delorean or sum? 😂

this^

yes they did, but when you see how they built their own extension you can see why they thought what they thought, why they were wrong, and why their product is still perfectly okay. these cables are fine. I just read the spec, and essentially I think the Corsair person was just confused and didn't realize that Nvidia built their adapter differently than they built their adapter, but both will work fine for a 4090 or any other GPU with ATX 3 that has ever been produced.

The Corsair one just uses 2 ground wires, the Nvidia adapter uses 4 ground wires and an IC to check them.

@@gucky4717 exactly. And let's be clear when we say "IC" we think of some complicated logic but it's really not doing that complicated logic. It's just counting the number of sense pins (old style) on the connectors and converting that to a two digit binary number.

That only applies to Nvidia's cable adapter. That's what Steve from gamersnexus was talking about when calling out Corsair. Not Corsairs own cable. The way this cable works is completely different.

did you manage to solve the issue, having similar problem.

Yeah... im pretty sure i remember this as well. Jays 4 to 1 was also connected only using 3 plus the breakout on one... not a good idea for OC.

Two plugs at the power supply side is enough, it's different with the adapter, but with the dedicated cable you can pull 600w no problem.

power doesn't affect the longevity of cards, voltage does, which may I add Nvidia doesn't even let you increase it this time around

Good point and I hope Nvidia hasn't done anything to effectively lock performance and constrain people into using their squid cables...

There is literally no difference in the power provider by corsair's cable and nvidia's cable when nvidia's cable has four PCIE 8pin cables connected from the perspective of the graphics card. As jay, and gamers Nexus have shown, the card determines its power limit based on what it senses from the cables. Both Jay and gamers Nexus perform the same experiment, a little bit differently, and got the same result. The new standard, in my humble opinion, is simple, easy to implement, and far superior to the hodgepodge of old power standards and pigtailed six pin and eight pin connections.

@@misterio10gre unsure of this reasoning. Power is just V*I. If currents constant and voltage goes up power increases. Heat in devices is mostly from resistance to current.

@@enntense card runs at around 1.045 stock voltage, my 3090 does like 1.2 at max voltage headroom Also you are outright incorrect, heat is directly proportional to voltage but inversely proportional to current

Because some people don't have modular PSUs, different modular PSU manufacturers can have different pinouts on the PSU-end, which is why it's advisable to never mix cables from different modular PSUs. Making a single cable to deal with all that mess isn't worth it, it's cheaper to make a short one, if you design it to go all the way to the PSU, there will always be people complaining it's too short/long... While it sucks for the consumer, it would be a silly business decision for Nvidia to do it any other way. You MIGHT however be able to get replacement cables from your PSU manufacturer to address this properly however.

Because by spec, you only need two 8 pin outputs. Pice 8 pins are 3 power, 3 ground, a sense a, and a sense b. The new 12 pin connector (which is actually a 16 pin, 12 + 4 sense) is essentially just two 8 pins in a new form factor that is designed to work with both older "dumb" PSUs and new "smart" atx 3.0 PSUs. The same type of connector and cabling is used in the CPU 12v power cables for stuff like the 12900K, and that sucker can draw almost 250W safely from one cable.

There are no problems, he literally bent the cable back and forth and nothing happened

no idea why they still use wires so small

I think that's for using the nvidia adapter. the coarsair one is for their power supply. Their power supply should be able to handle the wattage over that cable/connector from their power supply. Think about pcie power cables from power supplies. some have more than one 8 pin on a cable. It should be because the power supply can supply that ammount of wattage for those connectors. But if you're using the nvidia adapter, it only sees power from each connector. coming from your power supply, you're probably stll only using 2 separate feeds from the power supply even if it's 4 8 pin pcie connectors.

Yes. It's because the cable Nvidia provides with their FE cards has an IC in the cable itself, at least according to the GN video. The 16 pin connector is essentially just two 8-pin pcie cables connected together, at least when used on an ATX 2.0 PSU.

Which cable did you choose? I’m not sure which one to pick, I don’t see a 3 8 pin option

@@cnigs008 there's a 3x8 pin to 12VHPWR cable. I just ordered the new one a week ago.
