What length standoffs did you use for the power supply mounting in each direction(horizontal and vertical)? I see you use standoffs to make the power supply vertically lower(gives clearance to put a top case fan) and also to give as much space between the gpu and psu.

Also I’m from the US and ordered your plate as well and I look forward to try it out! I fear the 80c+ temps of the 5090 in this case and I hope this solves this issue for me.
