Splitting one of the pcie 8 pin cables on the Core X Chroma? (evga ftw3 3090 + razer core x chroma)
@olyvers26, Yes I am using that one (EVGA RTX 3080 FTW3 Ultra), and I got it to work. I used the method of splitting one cord into the 1st and 3rd slots and putting the second cord into the 2nd slot. It seems to be working without issue so far (both in terms of gaming and crypto mining). The only odd thing is that when I turn my laptop off or if it hibernates, the fans on the card kick to max until I unplug the thunderbolt cord or turn off the eGPU. This doesn't seem to be the case with everyone but it has been for me (using a Dell XPS 15 9570 and Razer Core X Chroma). Nonetheless it isn't a huge deal and it isn't damaging the card.
Thank you for your enlightenment.
One question still. You said you use a Core X Chroma. Mine is a Core X (Older). Some comments above say that the PSU must be a single 12 volt rail in order for it to work. Could you attach me a pic of the PSU inside the Chroma. I'll attach you a pic of my core x. I don't know how do I tell the difference, if this is single 12 volt rail or not.
Thank you for your help.
@olyvers26, I’m not great at understanding single vs multi rail either but you can compare your PSU sticker to mine here https://imgur.com/a/CvvUgqJ (the site kept crashing every time I tried to embed the image).
I believe the number of rails refers to the fact that there are two different rails for the wattage. The 650W line has the 12V labels. I believe the 100W line is separate and refers to the thunderbolt supply.
Yep, I think t same. The PSU is almost identical to core X, except 1.5A higher on 12vc and 12d on yours.
It should theoretically work.
I might just give it a try for this Evga GPU.
Thank you very much for your help.
@olyvers26, I believe the only difference between the Chroma and the standard Core is that the Chroma is about 50W more powerful. I’ve only seen the card hit up to roughly 380W under full strain so even if the standard Core can only supply 400-450W (even though the Chroma says 650W, I’ve read it supplies at most 500W to the card), it should be doable.
