I bought a cable from Amazon from a company called Fasgear, it was £23, was very well made and has been faultless. I pulled over 500w from the card during testing and the plug didn't even feel warm.

Uh Oh..... This makes me think about our friend from Northridge Fix.

Sometime, new tech mean step back instead of step ahead... Instead of doing a problematic 600W capable plug they should have tried to have more GPU power with with less W needed... Anyway...

Whats an alternative, would 2x8 pin be enough for 600W?

Because direct cables arn't the problem. The issue here is adding more than two connections, 12VHPWR simply isn't suitabel for that. ANY adapter/extension is unsafe to use, no matter which brand. The Corsair Adapter is unsafe as well, just no reports yet because it looks like dogshit and people arn't using it. If you can't close your case either get a vertical GPU mount or cable with 90 degree bend.

Plug is fine, adding more than 2 connections isn't.

There is no need for an alternative, just don't use any form of adapter/extension and you'll be fine.

Good to know. Personally, I never liked the idea of using an adapter, I prefer using a native cable.

As a sudden realization, screw-on terminals would be best. Those aren't going to slip loose, they ensure good contact, you can modularly add more wires as needed, they're dirt cheap to manufacture, they're easy to sleeve, and it can still be tool-less by having thumb screws. The only downside is you'd have to cap the unused wires.

I went a different route , WireView from Thermal Grizzly , with New PS with own cable. .[youtube=ZJbYSEPhErI]

Too easy to get it wrong

I got my cables from MODDIY https://www.moddiy.com/categories/Cables/12VHPWR-PCIe-5.0-Cables/

No, but the real question is "Do we really need extra 600W for a GPU even if powerfull? " ...

Its not a direct cable, its an adapter

That's the same risky solution as any other adapter/extension. You're driving up the resistance with any extra connection you make in the chain. If you can't plug in the cable either get a direct cable with 90 degree bend or mount the GPU vertical, any other solution is unsafe in the long run.

That one should be fine ,as you're extending from the more robust 8-Pin, just like the official adapter. Not ideal, but should be fine.

They also sell extensions i see, which arn't safe to use. Highly recommend to avoid this for example, as it's no different than an adapter: ATX 3.0 PCIe 5.0 600W 12VHPWR 16 Pin 90 Degree Angled Extension Cable - MODDIY

If they're color coded or perhaps use different shaped terminals, it'd be less error prone than the current "solution".

I was keen to try one of their 90degree but...went reddit, and there was carnage. Almost daily photos of melted cards/connectors. I went straight after buy to official corsair cable. Never used adapter provided with card. So far so good(since FEB). Still checking reddit, still burns, melts, despair. The connector project is fkd. To small for too much amperage and temps. Good my card is 450W only and most of the time I hoover around 230-330W...

Darn it. After hearing that the 1.1 variants of these cable mod adapters had been okay, I finally got a 180° adapter a couple of weeks ago. On both sides, this 180° Adapter's connectors have been sitting tighter than any cable I've had until now (the cable that came with our ASUS Thor Platinum II PSU actually slipped out more and more every day, while this adapter hasn't budged at all), it doesn't budge at all. Hopefully it didn't melt and fuse with the plug or something. Voltages seem to be fine, too, as the adapter+new cablemod PSU cable actually solved my card's low voltage problem that I had previously with all the various cables I tried (from the Nvidia adapter cable that came with the card over an old cablemod adapter cable to the two cables that came with our ASUS Thor PSUs all gave me down to 11.1V under load on the GPU 16-pin HVPWR Voltage depending on the workload, now I get a minimum 12.0-12.1V with the cablemod 180° V1.1 Adapter and the cable). With the recall, I don't know what to do about my cable routing without the 180° adapter, I've set it up around the 180° adapter so the cable can go pretty straight behind the GPU with only a very slight bend after 10cm or so to get into the gromit behind the bottom radiator. Otherwise the cable would have to be twisted and bent violently (which reportedly isn't a good idea with these 12VHPWR cables) to either the side or a little less to the top (if I can even get it through behind the top 420mm radiator and I don't know if the cable is even long enough to reach). Do any fellow gurus have any ideas? Here is my setup: https://cdn.discordapp.com/attachments/1098668169784217642/1187883469334909068/O11EvoXL234536874648_Small.jpg

No. The 8 pin PCIE power connector is rated for 150W. You'd need four of them to get to 600W "safely". Most cables that aren't crappy will actually do more and the connector is also well overspecced, but I guess they decided to play it safe with 150W. One would only wish they would have overspecced the 12VHPWR connector like this as well.

This is why i bought this for my 4090 Premium Individually Sleeved 12+4pin PCIe Gen 5 12VHPWR 600W cable, Type 4, BLACK (corsair.com)

Same here but with new york brand called J&D. Been pulling almost 98%TDP ( 497w ) for my bios modded PNY 4090 GameRock. Running since july / august with no issues or problem with temps or the cable extension itself.
