[SOLVED] Can random psu extension cables be dangerous for components?

I saw that cheap psu extension kit on amazon and I'm wondering if it could harm my computer...

Is it a good idea to buy off brand cables like this?
What are the risks?

It is not a good idea to buy off brand cables like those shown.

If there is some misconnection or faulty connection within the cable or plug a short could occur or the wrong voltage applied to a component .

Risks = smoke, sparks, fire, burned components...

That can happen even with brand cables.

However brand cables are more likely to have more rigid manufacturing requirements, adhere to product standards, and quality assurance measures in place.

There is still some risk but much less overall.

LOL!

18g wire isn't very good for a PCIe or EPS12V cable... never mind an extension. And connector pins can be of varying quality. And I'm sure I don't have to tell you about the impact on voltages due to resistance created by the additional wire length and cheap pins.

So then why are everyone recommending extension cables for PCs if it costs 45$ or more?

Even rgb strips cost less...

Why do you think you need extension cables?
Normally the supplied lengths of cables for a psu are adequate.
On occasion, a 8 pin cpu eps socket is a bit distant, and the only good solution is a short extension, but best to avoid even that if you could, even at the expense of a non neat bit of cable management.

Who is "everyone" and WHY are they recommending them?

Need some context here.
