For some reason I thought I heard the card comes with the 8pin x3 cable. I go to install the card today but there isn’t one included.my PSU didn’t come with one either. I only have 8 pin x 2. I don’t even see that kind of cable on Amazon. Was I supposed to get one with the card?

If both your 8 pins are independent cables you can split one of them into two 8 pins 

^^be careful not to use the split cable

What do I need to be careful of? According to the picture you shared under the 3pcie slot, it says it has a check mark showing it should be fine?!

4+4 is meant for CPU and normally won't fit into a GPU. The plugs are shaped differently

That is not true?

There is no adapter that can solve your problem. You are going to need a PSU with 3 separate PCIe cables. See my above post.

Hello!

I see these new cards have 3 of the 8 pin connectors, but my psu has only 2 cables. However, those 2 cables are split into 4+4 and 6+2 each. Would I be able to power this card with 1 cable connected to 1 connector and daisy chain the 2 other connectors with the other cable?

P.S. I have a Corsair HX750

No you need a new PSU as well. See above post.

Jacob has said multiple times that it is okay to use a Daisy chain for the 3rd 8 pin. 
 
if the 8 pin, or 6+2, has a daisy chain on it then the wiring is heavy enough to handle that kind of current and the power supply is spec'ed to support that on the port.  if the power supply did not come with daisy chain cables then do not add one to expand it as the port on the power supply was not made for it.

yea sorry, my point was specifically about daisy chain being only ok for the 3rd port. you cannot daisy chain 2x8pin into a single PSU port

Thanks for clarifying. Yes, the HX750 comes with 2 daisy chains. I was going to do what the picture does. I will only plug 1 cable to the 8 pin closest to the back ports and daisy chain the last 2 8 pins farthest from the back ports.

Thanks everyone, i used the 3 separate cables. The cables themselves are daisy chained, but i used the main (first) plns and let the other three hang there. 
 
For some reason i imagined one single cable with three things at the end. As you can see, i'm a bit of a noob. 
 
Got it installed and it seems to be working great. I'll keep an eye on things with the hardware monitor. 
 
Thanks again!

To clear this up, these are the preferred solutions:
 
1.  3 separate PCIe cables -> 3 PCIe 8pin or 6+2 connectors (any additional connectors will be unused)
2.  2 separate PCIe cables -> 3 PCIe 8pin or 6+2 connectors (any additional connectors will be unused)
 
In other words, if your power supply, from the manufacturer, only has 2 PCIe cables, and one of those cables splits to a second PCIe 6+2 connector, it's fine.  No need to run out and get a new power supply if you have one that supports option 2, above.
 
It may be a different matter if your power supply, from the manufacturer, only supports 2 PCIe cables with a single PCIe 8pin or 6+2 connector on them, for a total of 2 connectors available.  We would not recommend that you try to purchase a cable that would add additional connectors that your power supply doesn't officially support.  In other words, if your modular power supply only supports 2 PCIe connectors, don't try to buy a modular cable that would give you 3 or 4 total PCIe connectors.

I'm surprised you guys are okay with solution number 2. Especially with a 3090 FTW3 card. That would mean there would be a possibility of up to 300w going through a single PCIe cable. Personally I would want 3 separate cables. But I have always been against daisy-chained power cables personally for cards of any gen.

My AX850 has a single 12 pin in the PSU to dual cables (8pin) the entire length. Much like this pic. Would that be fine for a dual 8 pin 3080?

I'm using the CPU port with an extension braided cable adapter and it fit and is working with my 3080, but I'm not sure if this is good to do, and I will be upgrading my psu soon. But I've not had any problems.

This is incorrect.

Always use one connection per GPU power cable.

Actually it will work, not the best solution, but MOST PSUs under 850W don't have enough PCIe cable to run 3X separate 8 Pin from the PSU end to the GPU.

Don't risk it people, use a good PSU and 3 separate pcie cables. Daisy chains even if allowed put a lot of load into just one cable in the end you won't get away with it if something ever goes wrong. Better be safe than sorry. Don't put yourself at ease because RMA is good shipping the card for RMA costs a ton of money that could be better used elsewhere.

Agreed... but also think EVGA needs to get on the same page. You have a couple EVGA reps making the statement that its ok to daisy chain and another condemning it. I for one think this whole daisy chain argument is getting blown way out of proportion.
