I'm not sure if this is the best place to post, but does anyone know if these bad boys are sold anywhere else?

https://ttstoreusa.com/product/4-pin-molex-connector-for-smart-series/

I have this PSU (https://www.newegg.com/Product/Product.aspx?Item=9SIA0ZX2C39774) and it only came with 2 of these cables that are needed to connect to my PCI risers. I figured out from trial-and-error that I can use 1 cable for 2 GPUs but not more than that or ethOS becomes unstable. So I'm currently maxed out with 4 GPUs and the other 2 are sitting in their boxes :(

Thanks in advance!

I have the 1000watt version of this PSU and can run 5 gpus off of the Pci-e connectors (3 cables with 2 (6+2) connectors each).
You should be able to connect more than 4 using just those (unless you are using cards of varying lengths).

The molex 4 pin cables are better suited for risers (not ideal for gpu's) but I believe you can get connectors like the ones below for your gpu's to run of the molex. each molex connector can deliver upto 75watt so keep that in mind for the card you are running.

Just to confirm, you're actually looking for a modular cable of molex connectors for your PSU, right?

A 6-pin PCIe (female) to 3x 4-pin molex (male) passive adapter would be an unusual item, since all of the molex connectors would be missing the 5V line.


The PSU end of modular power cables are not standardized well, and 6-pin PCIe power connectors are distinct from the 6-pin connections on the side of a modular PSU.

Correct the psu end of the modular cable looks similar to the 6 pin pcie 6 pin cable.

Yes, it's the molex 4 pin cable I need for my final 2 risers :)

I have enough cables to power the GPUs.

The problem is I need LONG cables, like 2 feet, since my final 2 cards are the furthest away from my PSU.

Yes, that's correct. And not only that, I need a LONG cable, approximately 2 feet, since my final 2 GPUs are the furthest away from my PSU.

These cables came with my Thermaltake PSU, except it only included 2 of them and I need 3 of them.

Also I need 6-pin PCI MALE to 4-pin molex FEMALES (opposite of what you mentioned) ;)

I would check the literature and box contents.
There should be 3 cables as that is what was included with my PSU (2 connectors per cable).
If not then contact thermaltake's CS and they will look into it.
Once you do have the cables you'll need to move the gpu's a bit closer to make the 3rd cable reach (as running of the pci-e cable is most ideal instead of messing around with molex connectors to run the gpus-depnding on what you're running).  doesnt make sense to be running a 1200w psu through molex (just my 2 cents)
