sorry if this is a dumb question but I just bought this 4080 Super for my first build and honestly the cables that came with the power supply are just... ugly. They are all stiff and black and have these weird extra bits hanging off them and it looks like a total mess in my case. I saw some pictures on Reddit where people have these really nice colored cables that look like braided rope? I think they are called sleeved cables or something?

But I am really scared because I read somewhere that you cant just mix and match cables from different boxes or your computer will literally catch fire and die. That sounds terrifying and I dont want to ruin my expensive parts. I have about $100 to spend on this and I want something white or maybe light blue to match my theme. My logic was that I could just buy them on Amazon but then I saw some talk about extensions versus replacements and now im totally lost.

So far I have looked at:

• cablemod (everyone says this name but their site is confusing)
• some random ones on amazon that were like 30 bucks
• the ones that came in the box (the ugly ones)

Like if I buy extensions do I still have to hide the ugly ones? Or do they just plug into the card? I'm in Oregon so shipping from US places is better. Does anyone have a brand they like that is safe for a beginner who has no idea what they are doing...
