Question How hot do power cables get? (Damage/Fire Hazard)

[FlowersForMegatron]

I'm trying to hide some cables (Ps4, chromecast, TV and power strip cable) and was thinking of using pipe insulation.

Here's a pic:

I Bing'd it but didn't find much. Is my attempt a bad idea?
If so, please call me stupid quickly since I don't wanna damage components or burn my apartment down.
Thanks!

Given the correct gauge, not hot enough to worry about.

There are many, many premade cable runs.
Just as an example, not an endorsement of this company:

How hot wires get depends on how many amps are flowing through it, and they'll only get worryingly hot if they're exceeding their rated limit. If it's from a reputable company, the cable will be more than capable of handling the current the device is expected to draw.
