I intend to buy a pcie riser but i see there are 2 types. One is pcie x1 to x16 and another one is x16 to x16 basically just an extender. Which riser should i be using? Are there any difference? I will be using it on a hp compaq elite 8300 sff where the pcie x16 is around 80 watt max
X1 to X16 is usually bought by cryptocurrency miners to plug their mining GPU to the motherboard. They don't care about the PCI-E bandwidth. So the GPU only getting X1 PCI-E speed. No problem for such application.X16 to X16 is an extension cable. Sometimes people want to reposition their GPU to show off their GPU and lighting in certain casings, means the GPU fan face the side rather than the usual face bottom. You get full X16 PCI-E speed.
From what I know for your particular 8300 SFF, the PCI-E x16 slot official spec from HP only can provide 35W max to the slot. Only the CMT version can output a full 75W, not the SFF.
