Computer Not Starting Up Power Supply Or Motherboard

That's the top motherboard that supports the dual power supply. It has everything I need.

The case itself is fairly sturdy, with space behind the motherboard mounting wall for managing cables, and in the power supply bay if using a standard size power supply (600W EVGA fits great). With two different PSUs, the screw hole for the upper right position (facing the rear of the case) did not line up, so it is held in with only three screws. Even so, it seems quite secure. There are many ports for routing cables, several of which have rubber grommets to keep the holes closed and improve appearance. I installed five PC Cooler Corona fans and an MSI full ATX motherboard with plenty of room to spare. The fans and case lighting system are being managed by the MSI Mystic Light system, so it is all coordinated. The front light bars are better than I expected. Note that the included fan is RGB, but it is not ARGB. It has a beautiful soft glow which runs in a continuous rainbow pattern, but it is not controllable. The only design issue I found is with the cover for the vertical video card installation (which I am not using). Once I mounted a two slot video card in the motherboard, the cover would no longer go back in place correctly. I think this would happen any expansion card you install; they didn't allow for the space that the backplanes take up. I had to use a small wire tie to secure the upper end of the cover to the case, as the original screw hole no longer aligned. I wish it had a reset switch, but I knew it did not before I bought it. I have seen a few complaints that the glass is too dark. It seems about the same as other darkened panels I have seen, so I think it is fine. Case was well packaged in double wall cardboard, which was good because FedEx went through first layer in several places, and through both layers at one location. Fortunately the penetration did not dent the case wall. Overall, I am very pleased with it.

This power supply works well and does the job! The modular connectors for the motherboard are not easy to connect the cable to; instead of 1 above the other, side-by-side would be much better!

I just move all my components (except motherboard and power supply) from an mid-Atx case to the NR200, and I was able to keep the same temps I had in the bigger case. Rtx3090 (from an Alienware PC) Ryzen 9 5900x, 64Gb Ram and 2Tb m.2 ssd drive, 850w SFL Power Supply.

It's a power supply.

The headline says it all. One caveat: if your computer has a noisy power supply the noise will likely turn up in the output.

This motherboard is just what I need for a midrange computer

Great power supply.

is there a power supply included?

Easy to use AND it comes with the power supply when some do not.
