Are there any negatives to using a PCIE to M.2 adapter?

[CxRizzle]

I have an Asus IX Formula motherboard and it has room for 2 M.2 drives, but, one of them is on the bottom of the board, facing up. So it forces your drive to stick up in the air and it looks awful. Also feels like I'm going to smack it if I'm working with the insides of my case. It's just badly placed and awkward. To remedy this, I was gonna pick up one of those PCIE to M.2 adapters like this

Maybe a dumb question but are there any cons to doing this? Like does it share bandwidth with the GPU (I thought I read this somewhere) or anything like that?

can't attest to the quality of that adapter. I'd suggest looking around some more and doing some research to find one that won't be a piece of crap.

However, seems like you missed out on using Google to search for an answer to if using an adapter has any negative effects.
I found this as one of the top results in Google and I didn't even search for the question. I actually initially searched for PCIe M.2 adapter and it was the fourth link down.

But to answer in short, no. There's no negative, since a good M.2 drive uses PCIe lanes instead of taking up SATA lanes to do it's thing and using PCIe lanes instead of SATA lanes is faster all around.

Anything plugged into PCIe slots share whatever available lanes the CPU itself supports.

So if a CPU supports 24 lanes of PCIe, then a GPU (while it can use up to 16 lanes) typically uses 8 lanes. Then something like the PCIe M.2 adapter uses up to 4 lanes. So even if the GPU used 16 lanes and the adapter used 4 lanes, there's still 4 lanes left on that CPU.

Refer to the specs sheet for your CPU to find out how many lanes it supports. But generally no, it won't take away from your GPU performance, and your GPU won't take away from the M.2 performance.

Here is the ASUS card.

Here is a discussion on how the # of lanes vary by processor . Intel now totals those from the processor with the lanes connecting through the chipset to give what it calls" # of platform lanes" in its processor specs.
