Recommended cable configuration for 3000 series cards

I have been using an 8 pin connector coming from the psu which is daisy-chained to two 8 pin connectors (1 cable) on my 3080 since early November. I have an ASUS TUF 3080 OC which requires 2x8 pin connectors and a Super Flower Leadex III 850W 80+ Gold which is in the A tier LTT tier list. I have had no issues yet but I was watching Linus' video today with him rebuilding a pc with the verge guy and just found out now that a daisy chain is not recommended. I just researched and apparently the daisy chain is definitely not the smartest choice, could be a fire hazard. I have 2 daisy chain cables that came with my psu, could I plug both into the psu and have an 8 pin plugged into each with the other 8 pin dangling on each cable? Would they act like a single 8 pin cable or would I need to order two single 8 pin cables?

You are pulling more than the recommended 150 watts from the cable.

To see what you are using per cable use GPUZ under sensors.

Looks like this. I have the ROG Strix OC 3080 and it can use over 450 watts so it uses 3 cables.

The last time I daisy-chained was with my GTX 980 ti(1 8pin and 1 6pin) SLI setup. One of the cables eventually shorted and took out a video card. Fortunately there was 45 days left on the warranty and to my surprise EVGA replaced it.

Yes that is perfectly fine. I would just tie the lose end, with the other 8pin, to the cable so it looks cleaner and doesn't dangle around. You don't need to get extra cables that don't have the daisy chain ability.
