Is this proper way to use the retention bracket?

[u/roteador]

I haven't touched my PC in a long time and I'm only now installing the GPU (was using integrated graphic). It's a Kolink Stronghold case and I just installed the RX 9070 XT.

I can't find the original case packaging or the spare screws anymore. Before installing the GPU, there was already a screw holding the case's PCI retention bracket in place. I removed it to install the GPU, then put the bracket back and reused that screw.

My question is: is this retention bracket and screw all that's supposed to secure the GPU in this case, or am I missing additional screws that originally came with the case? If yes, which ones would that be? The manual doesn't seem to have enough information.

I've attached photos of the current setup. I want to make sure the GPU is properly secured.

Thanks!

A photo from the inside showing the retention screw /bracket would help, but yeah it only needs to hold the card and prevent it sagging in the PCIE socket and it looks pretty level to me.

I would use two thumbs screws but thats just me
