The power supply comes with the following cables: 1x 20+4 PIN ATX power connector, 2x 4/8-pin EPS12V (not explicitly stated, but typical for such models), 4x 6+2-pin PCI-Express and 8x SATA as well as 4x Molex. There is no specific information on a floppy connection in your data, but these are often included.
Hello alaino
I also built my PC myself last December.
As I was doing this for the first time, I wanted to make sure that everything fits together.
To find out the compatibility of the components, I did the project with the help of https://pcpartpicker.com/.
I hope I could help you and wish you a nice day.
