@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.

@birrbles

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.

I have something of an update on this thread with longer term lessons learned since it's been what, more than a year?

  • In the last year, I've run into sporadic stability issues with the setup wherein the drivers crash and I lose output until Windows reloads the driver. This has never been resolved with any driver update that's taken place in the last year.
  • However, and this is the interesting part, I started mining using nicehash in the last month, and for as long as Excavator has been running, this setup has never crashed. I'm now a month in without any stability issues at all.

My guess is that there's probably an issue with a low-power or standby-ish state (not Windows, just the hardware itself, possibly with the Core X Chroma) that's causing the crash, and with mining persistently running in the background, it's never had a chance to fall down into any low power states.

For those wondering: I've run Nicehash at Medium consistently without issues. I've yielded almost no benefits running Nicehash at High or Extreme (wattage ticks up from 270 at medium to 280+ or 290+ at high/extreme but I'd almost never actually make more from it, making me wonder if it's being limited by the external overhead). That said, I've also never encountered issues running Nicehash at High or Extreme, but I'm comfortable running it at Medium.

Hope this long term update does some of you a favor.

Recently brought a Razer Core x Chroma and an MSI Radeon RT 6800 XT 16 GB graphics card. The problem is the power supply unit (PSU) in the Razer has only 2 x PCI-E 6 + 2 pin cables. The Radeon RT 6800 Xt requires 3 PCI-E power cables. 

I had considered buying a generic EPS 2 * 8 pin to Gpu 12 pin power cable connector as an easy fix but was worried that the Razer Core X Chroma PSU at 650 watts would burn out. I believe the power consumption of the AMD Radeon RT 6800 XT is about 300 W.  

Has anyone else encountered this issue? If so how did you get over it?  Any found that the Y cable worked or do I have to try and replace the PSU in the Razer Core X Chroma with something like a 850 W PSU? 

Has anyone found a suitable replacement  850 W power supply for the Razer Core x Chroma?  The replacement  must have the same dimensions as the old one (150MM  High x 86MM wide X 140 MM long)

If so what did you end up doing?

Help appreciated!
