I currently have 2 RTX 3090s in the PCI-E lanes 2 + 4

I want to buy a PCI-E x 1 GPU Riser Cable Extender Adapter to put a 3rd RTX 3090 into my PC
Something like this: https://www.amazon.com/FebSmart-Litecoin-Extension-Ethereum-Extender/dp/B08HHSPPBD/ref=asc_df_B08HHSPPBD/?tag=hyprod-20&linkCode=df0&hvadid=475692076734&hvpos=&hvnetw=g&hvrand=18198048097816753973&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9004364&hvtargid=pla-1090674342638&psc=1

Can someone who is knowledgeable shop for the BEST PCI-Ex1 riser cable that is compatible with my motherboard?
I hear that some bad riser cables can get their capacitors burned so I want to buy the highest quality one.

Remember: This motherboard is only a PCI-E 3.0 board. The point of 3 RTX 3090s is for mining.

What is the model number/brand for the one you said was the best. Links to website purchase would also help!

eEbay it. White seems good to me from this guy.
Faster option.

Is GPU mining still anywhere close to being profitable?
To answer your question, any riser that has aux 12v power will do. I would put all of them on riser cables to protect the motherboard +12V PEX lines.
The Top Left of those is the better option, suppllying all power levels with dedicated voltage regulators.
