I was starting from nothing though and I am trying to limit the next time I need to change parts, I say this as someone about to buy a new AMD 3D cpu but tbf that was always my plan, I just built the PC in Nov as it suited me.
Yeah the 16 (12VHPWR) into the GPU, off that is an adapter with 3 or 4 PCI-E x8 male connections. It is really unwieldy so many opt to get a nice braided cable from cablemods.
Hmm would have to check my PSU it's knocking on a bit now, old EVGA G2 850, sure it would have enough mind, only got 2 years left of warranty..
