Hi, I have tried getting in touch with EVGA support but no answer!!! So can anyone tell me if my EVGA 220P21000XR SuperNOVA 1000 P2 Power Supply 1000W 80Plus Pl, would work with my ZOTAC GAMING GeForce RTX 4090 AMP Extreme AIRO GPU ?? 
If so what power connector would be best to use with it??
Thanks

I see you have been lurking for a few years.  Congrats on your first Thread & Post
 
YES, it should work
 
That PSU have Qt6 - 8-pin PCIe outputs ..... so that is plenty of cables.  Use individual cables for each connection to your GPU (in other words, do not use the second connection on any of the PCIe cables) &
 
 
The - Requires (4) cables / connections to the adapter
 
Recommended Power Supply of 1000W
 
 
 
 

Hi Cool GTX, thanks for the response. I understand the need for 4 separate power cables but I believe I would need then to use the 4to1 adaptor  that came with the GPU. I have heard that using inline adaptors can cause issues, do you know of anyone that provides a direct 4 to 1 (PSU to GPU ) type cable for connecting the GPU to the PSU?  Cheers

Yes, the adapter is Required & was mentioned in my reply, I made it bold font in the above quote for clarity.
 
The root issue is with the 12-pin design not being robust enough for typical use; you must limit stress & disconnect/ reconnect cycle on the 12-pin connector
 
 
I have several GPU that use the 12-pin connection (though different brand than your 40 series) - no issues over a year later
 
1) I leave my 12-pin adapters connected to my GPUs & like that I can disconnect the 8-pin cables from adapter when I need to organize cables or move the GPU
 
2) Do not force a bend in the adapter near the connection (stresses the connection) & keep the bend large as possible
 
3) I support the PCIe cables by using zip tying the cables in position to reduce/ remove stress from the 12-pin connection
 
This is what you need to understand Connect/ disconnect cycles 8-pin PCIe to ATX 12VHPWR Adapter Included with RTX 40

NO, I do not know of a 4 x 8-pin to 12-pin cables, offhand. 
 
Check with custom cable Mfgs.  Most seem to only offer 2x 8-pin to 12-pin cables
