I had a 1660Ti, and it had a single 6-pin connector

ASUS TUF 3080 has two 8-pin connectors, and I realised that I had daisy-chained the 8-pins together.

The card has 2 plugs and a PCI-E slot, total power delivery is 375W (150+150+75), while the card’s TDP is 320W. If I have daisy-chained cables, will it affect power delivery?

I have a 750W PSU (Corsair RM750), is it ok to run the card with daisy-chained connectors?

I have a 5800X (non-OC), and a lot of fans and drives, so I am worried that the wattage might not be enough for the 3080 in intensive games, when it’s daisy-chained (even though I played MSFS at decently high settings and everything was ok).

Am I overthinking it or should I get seperate cables to power my 3080?

EDIT: redid the cables, just in case
