Re: Would this all fit?
The motherboard will fit in an ATX standard case, but make sure your case has enough room for the card, it's a gigantic 10.5" long.
The PSU has two 6+2 pin connectors, so you could run the card fine with no adaptors required.
The standoffs for the motherboard should come with the case. Your motherboard will come with the required screws as will the PSU.
