Should boot Winsows just from a USB to check right, no need for installation?
Is a 750w power supply enough for this processor (i9 9900K)? checked on this
power supply calculator site and it recommends using min 400w so with 750w think it has plenty of headroom.
For the cooler think will go with the NH-U12S.
For the MOBO, still undecided between Gigabyte z390 UD V2 or Gigabyte z390 M, the latest has 2x m2/nvme slots and its cheaper, but cant seem to find that many hacks using it so im leaning towards the first one..
