[SOLVED] Installing a new operating system onto an old SSD with an OS already on it

[Kirky-No-Werky]

I'm doing a new build and wish to use my current SSD for my clean installation of Windows 10; currently the SSD is already running Windows 8.1.

As the SSD is already running my old operating system, will I need to wipe it? And if so will I need specialised software to do so safely?
If not, do I need to run an OS through another storage medium to delete the partition on the SSD housing the OS?
Or would I need to install Windows 10 onto a separate clean storage device and move it later?

Note: my new build will involve a new motherboard and CPU but NOT a new GPU, incase that has any bearing on how to do this. Also, I will be installing Windows 10 via USB with a downloaded copy.

TL;DR - Can someone give me an idiot-proof step by step for installing windows 10 onto my SSD, which is my primary storage device already running Windows 8.1.
