To get max performance from this unit I recommend using the gpu and cpu at the same time.
This unit needs external cooling, so you can either add some fans, or put it in a case.
It uses only (1) 8 pin wire.
Free fast shipping.
And you also need to add an operating system. This can either be on a usb stick, or a nvme drive.
