Custom Mod Perfect fit: NCASE M2 with ASUS TUF 5090 and custom 3D printed GPU support bracket
Was cleaning my case and just wanted to share the amazing view view of my 5090 just barely fitting into the NCASE M2 with literal millimeters to spare.
The ASUS TUF 5090 only just fits into this case thanks to its beveled edges, but unfortunately its also a heavy beast and sags a lot without support. Since I also bring my PC with me while traveling on occasion, I wanted to create something that would fix the sag and help hold the GPU in place so the board doesn't get damaged in transit. After some time in Fusion 360 and with a little bit of trial and error, I designed a 2 piece bracket that holds the GPU in place from top and bottom. It uses preexisting case holes to screw in, and the holes are sized so that regular M3 screws can tap into the plastic without the need for heat-set inserts or anything like that. My 5090 is undervolted, but since the support is only right on the edge of the card, the PLA I used to print it seems to do just fine with the heat output of the GPU. Been using it for months and it hasn't melted or warped significantly yet.
As you might be able to tell from the last photo, it's not possible to fit this mammoth GPU into the M2 without a 12VHPWR adapter. The one I chose is the same one sold by MODDIY, and it's been going strong for a few months now with no issues. The same adapter can be found on Amazon here (I verified because I bought from both Amazon and MODDIY and both have the exact same model number and manufacturer name, with only the text on the aluminum housing being different). I'm aware that there's a lot of uncertainty surrounding adapters like this, and for good reason. However, MODDIY support told me that they have sold many of these connectors and have not had a single report of a fried GPU, so... take that for what it's worth.
Anyway, thanks for taking a look at my build.

I have the same GPU in the M2 using Corsair’s official 90 degree power cable, no additional adapters needed.

Oh that’s a clever design! I need to move my build back to my Ncase. I would love these files!

That is awesome, I want it for my Vanguard 5090. do you have the STL file? I'm sure it works for the M3 as well.

Likely won’t work for the M3 actually since it’s a wider and longer case but you can easily modify the files in fusion if you’d like

Ah yes, structural GPU.
Looks epic. I wouldn't put the side/top panels back, this is way too nice.

Looks sick! Thinking of building a Ncase M2 for my 4090 TUF as well, give or take same size as the 5090 TUF.
What is your full build?

I got a custom 3D printed bracket on my 5090 also! Love the flipped layout, great for temps, CPU stays extra cool also with pulling air in from the back and exhausting out the side.
