I connected about 10 LED lamps (a single one seems to draw about 14W) to a 200W power supply in parallel and the PSU is reaching a temperature of about 53 degree celsius (127 Fahrenheit). The First segment of the Cable before any major splits happen and the most current flows through is reaching about 38 Celsius (100 Fahrenheit). I am using a 0.75mm^2 cable (20-19 AWG) and I am worried that that load could be too much for the cable to handle. I am worried of a cable fire. If anyone can tell me if those numbers are okay I would be glad.

Assuming you're on 12V, pulling 10+A through a 0.75mm2 presumably multicore cable is definitely too much. You can easily google this though.

A chink cheapshit PSU rated at 200W is also probably not really meant to handle 80% load constantly, if I wanted to power 150W of LEDs, I'd buy at least a 300W PSU. 

That aside, your cable temp isn't that terrible, 38C isn't going past any ratings, but it's not good for longevity to be on the edge. I'd use at least 1.5, probably 2.5mm2 cable for 10-15A loads.

Thank you, that was helpful. Next time I should plan things out more.

what are you smoking

depending on mounting 1mm is enough for 10A

consult a table before spouting bullshit

There's a table right in that post that says the same thing you fucking retard.

yet the contents are retarded

2.5mm2 for 10A

crazy

the contents of your post I mean, the table clearly shows that 1.3mm2 is enough for 10A

the table is bad still, because it makes a great difference if the conductor is on a tray (best), mounted on a wall, inside a wall embedded in mortar, or inside a wall in a tube (lowest max alloweable current)

Some advice from experience don’t use the Chinese ones especially not anywhere near they’re load limit, had a few near-house fires. Paying an €10 more for osram htm is worth it here

This is a recommendation for a DIYer that doesn't know shit about electronics and is running the cheapest chinkshit hardware, and the load isn't 10A peak, it's 12A constant. Going above the bare minimum doesn't seem like such a crazy idea.

Total amateur here ... but can you move the parallel wires closer to the PSU?

Start the "splits" earlier or at the PSU itself, so there isn't any length of 20AWG wire carrying all that current?
