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.

May i know where u get the official spec? I searched the internet but could not find it. However i have seen people upgrading the elite 8300 sff with a gtx 1030 or gtx 750 ti

It used to be published by HP. This model EOL already though, I only manage to find this. However this is the official spec list.

Someone in youtube managed to use a 1050 ti Low Profile which consumes 75 watt in the hp compaq elite 8300 sff

So safe to assume i can go up to 75 watt gpu

Longevity is definitely not guaranteed though

Also, the problem is budget - if you end up spending over RM1K for all this you might just as well get a Sandy Bridge or even a used first gen Ryzen build

How much that HP SFF costs though
