PCLe cables connection

Hello everyone! 

I have a following question to people who know difference between connection of PCLe cables. 

The question is following:

I have Sapphire NITRO+ Radeon RX 7900 XT Vapor-X AMD 20 GB GDDR6 which has 3 x 8-pin stromsteckers, but my PSU has only 2 x 8-pin stromsteckers. So, could I connect 1 PCLe cable from PSU directly to graphic card, but 2 PCLe cable will be splitted from PSU to two 8-pin stromsteckers?

Example attached below.

Thank you for your reply in advance.

You can use a splitter to create 2 PCIe GPU Power cables but it isn't really recommended.

The trouble with using a splitter is many times the PSU can't handle the needed power to 2 GPU power connectors from one PSU connection.

You could just purchase a Molex or SATA to PCIe cable adapter instead and connect all 3 GPU directly from the PSU to the GPU card like these from Amazon: https://www.amazon.com/Cable-Matters-2-Pack-8-Pin-Inches/dp/B01DV1Z428/ref=sr_1_5?keywords=gpu+power...
