So my ITX PC came today in the mail but when I was setting things up I saw that there was no power cord? Does it not come with the PC? Sorry if that's an obvious question, I'm pretty new to PCs.
They've also included a sheet inside with instructions on how to install windows but their method is to download the windows iso file onto the computer and using some program called "Ventoy"?. I've already made a USB with the windows installation files by watching this YouTube video. Can I just plug that in and boot the PC up?
