Power Supply 0.75sq (0.75mm2) fiberglass braided cable can be used to make custom cable for PSU 750W?

[topsecret]

I bought this type of cable to make a custom cable for my SF750 power supply, with a length of around 30cm or less. However, I'm not very familiar with the cable size conversion chart, so I ended up buying the 0.75sq type. Based on what I found, it's approximately 19AWG.

This cable is rated at 600V and can withstand temperatures up to 300 degrees.

I'm wondering if it's safe to use for making custom cables? If not, should I get a different size, like 1sq or 18AWG?

Thank you for the advice.

Are those aluminium strands ? You might want to reconsider making cables out of that, it has a much higher resistance than copper meaning you need about 2/3rd bigger gauge.
