RTX 4090 Adapter

[luckeYpublic]

Hi,

 

I have an ASUS TUF 4090 graphics card, and I saw the concerning pictures about the 12VHPWR adapter's melting. I would like to buy a new, more reliable adapter for the card, but I would like to ask 2 things about that:

1. What brand are you suggesting for the adapter, that is usually delievers quality products?
2. Most of the adapters have 2x8 PIN to 12 PIN. As far as I know it should deliever 600 Watts, but a single 8 pin PCIE's maximum consumption is 150 Watts. So how can those adapters deliever up to 600 Watts with mathematically 300 Watts?

Right now I have 4 different 8 PINs connected to my Corsair HX1000i that goes into the provided adapter.

 

Any suggestions and answers are appreciated, and sorry for my English.

If you want a pretty much guaranteed to work, get a new ATX 3.0/PCIE 5(w/e they want to brand it) PSU with the connector included with it and you should not have an issue. The current main suspect is the adapter itself, so if you can avoid it by just buying a PSU that comes with the plug on its own, no adapter needed

Yeah that would be great, but it looks like to me that it's impossible to get my hands on an ATX 3.0 PSU in Europe at the moment.

I fear its the same with the cables, I signed up for Corsair to let me know when their cable comes in stock even though I don't have a card yet.

 

Personally if I manage to get a 4090 before a cable, I will just drop its TDP.  It loses barely any performance at 80% and most of the time I can probably get away with 50%.  That should at least reduce the chances of problems in the short term.

Cablemod is a bit more expensive, but has the "protector" to keep you from putting too tight of a bend radius on the cables coming out of the connector.

Jay talks a bit about them here.

Just note that the cable he is using with the metal protector is not on that list. You'd have to get it through the configurator.

Does the 8-pin directly go into the psu like the Corsair 12VHPWR cable? It's because EPS/PCIe is same on the PSU side and EPS can deliver 300W+

 

I would wait and get a Seasonic Vertex, because you can never go wrong with Seasonic.

Cablemod is backordered I ordered mine on Oct 1st, it just shipped yesterday (from China).

Hi it is more safe to use seasonic prime px 1600w psu this psu include new 12VHPWR cable instead of this nvidia adapter? 
 

i dont want to melt everything so i’m worried please let me know soon idont know what to do

As long as each power pin has its own cable, that seems to be the issue with the Nvidia adapter.  Sharing the cable with multiple pins on a delicate easy to break bridge.

The adapter is fine as long as you don't put hard bends on it.

That is a depends.  There are variances on them and different manufacturers apparently.  The one Igor had tested was very easy to break.  Jay did everything he could, and it didn't have issues.  Seems some use a method other than soldering that is way more robust (I believe I heard punch down).

Cablemod 3x8 pin to 16pin cable for that specific power supply

Thank you! Can you tell me why the 3x8 pin instead of the 4x8 pin?

4x8 pin is completely redundant, and it's sold out for a long time. The 3x8 pin will be wayyyyy more than enough and easily provide the full 600 watts

I see. I already ordered a couple hours ago a 4x8-pin to 16-pin CableMod cable. Do you think should I cancel it or it will be fine?

No it's fine I just think they are backordered a few weeks

Get the Corsair cable direct from them. It's the best bet for your PSU and your GPU.

It took my 3x8pin 26 says to make and ship (not custom) it will probably be 1-2 more weeks as it's coming from China.

When I ordered they didn't have the 4x8pin available yet.  Cablemod has stated even for the 4090 more than two is redundant.  I just feel a little bit better with 3.
