System powering on questions

[parker_307]

So I know to turn the pc on motherboards will have buttons on them too power them on. But when I shut my pc down will I have to turn the psu off

No,
The PSU's power switch only needs to be turned off when doing physical maintenance inside your system.
If your replacing, or cleaning something, turn the switch off.
Otherwise, leave it alone

I assume this is the power supply your referring to:
https://www.newegg.com/Product/Product.aspx?Item=N82E16817151093
as far as I can tell it only has one main power switch on it.

As for motherboard and RAM compatibility, the motherboard's specs should tell you the speed of DDR4 memory it can handle (Ex: DDR4 2400) and the rated voltage.
It can be helpful to input your parts into https://pcpartpicker.com/ . As its pretty good at spotting incompatible hardware.
