The power supply shouldn't be an issue. It's 400W, and allows for a max of 324W combined on the 12V rails. The RX550 only demands 50W, and the i5-750 requires 95W.

That leaves over 150W remaining for everything else. You've definitely got plenty of power for your system's needs, assuming you're not doing anything like running 3 or 4 hard drives, etc.

The only thing I can't say is whether that's a high-quality power supply or not, as I'm not familiar with many power supplies.
