There is a pretty neat way to mount ATX PSUs in the CoolerMaster NR200P:
The traditional way of mounting the ATX or SFX PSU in the NR200P is either on the backside or parallel to the front.
With a quick modification, it is possible to mount the PSU to the front of the case. This opens enough space between PSU and backpannel that a fan can be installed.
There is one more thing: Larger PSUs can be installed.
This is a Corsair RM850x shift with a length of 160mm which wouldn't fit with the first-party ATX-mounting bracket. Technically a RM1000x shift with 180mm would also fit as the cables are shifted to the edge of the PSU. A 182mm long LianLi Edge might also fit this case. With a traditional PSU cable location, I wouldn't go larger than 160mm (still 20mm more than the CoolerMaster solution).
How?

- You will lose all of the 2.5" mounting points and the pump location and void the warranty.
- On purpose or accidentally CoolerMaster designed the 2.5" mounting hole distance is exactly the ATX-PSU mounting hole pattern and with the perfect distance from the tempered glass side pannel (PSU is close to the TG-side pannel with enough distance for the cooling fan to still have access to air). This is so lucky coincidence that one might believe that it was designed on purpose like this by CoolerMaster with this mod in mind but never.
- To open up space for the PSU exhaust and powerplug create a cutout in the front panel. I used the pump mounting holes as guidance/corners and slightly extended it near the power plug.
- 3D-print a jig or stencil to help with drilling two new mounting holes at the top.
- Install the stencil with the 7mm pins to align it (there will might be minor wiggle room depending on print tolerances as the pin is 6.5mm and the hole it indexes of is 7mm).
- Drill the 3mm pilot hole and widen it to 7mm holes.
- Move two of the rubber parts there and enjoy a decoupled ATX-PSU mount.
- You will need longer UNC 6-32 screws. Without the rubber bumper, the normal screws can be used.
- Enjoy your Corsair RM850x shift in the CoolerMaster NR200P.
- (you can hide the extra length of the original PSU cables behind the PSU for clean aesthetics).
