StingingVelvet: I'm sure it was overkill but I just wanted to be sure. That's probably why I was like "IT'S NOT POWERRRRR" lol, cause I knew I spent too much making sure it wasn't. I'll look around for that cable since you think it might be different, but I did buy a Corsair replacement. And yeah I used three discrete cables for the three slots.
I'll look into undervolting, I've seen a lot of people mention that on Reddit and such.
Not sure whether the one you bought separately is different from those 2 you had included (iirc not all Corsair cables have inline caps), but they should be marked as pcie/gpu cables + they are pretty stiff and have a black heat-shrink sleeve under which are those capacitors. Sometimes the sleeve has uneven shape or visible bumps because of the caps inside. They are rather useful for high transient gpus because they dampen those short spikes/ripples, which could otherwise lead to crashes.

Undervolting is a simple thing that's around for a long time, but since each gpu is different, it takes some trial and error to find the sweetspot for your sample, your build and your needs. I don't have the same card, but there are probably some baseline clocks/voltages/power targets out there on web/forums, something to give you a headstart at least. With a top of the line card, you probably don't need to touch power target at all and set the clocks at stock value (as a baseline or the advertised oc clocks the card came with), and undervolt from there.
If you want a simple one-click undervolt, try that automatic one, but it's nowhere close to the ideal outcome, but still better than out of the box and note the difference in stock core V vs auto-undervolt V. Sometimes the auto result is pretty underwhelming though, like -10 mV etc. My old Vega was the king of undervolting, -148 mV on the core for max power state, while maintaining the same power target and boost clocks actually went up under full load because it ran cooler.
