as julienruc said, the CXM 550 is better than that cooler master.
Reason why shall be listed with reasons why the Cooler Master you were looking at is bad.
It is only 80+ rated. This is bare bones and very basic and not very reliable. An 80+ Bronze is better, and Gold is even better than that.
The order goes like this from low end to high end.
80+
80+ Bronze
80+ Silver (not relevant anymore, Gold replaced this standard. Can still get them but not recommended as price and performance are worse than any Gold you can find.)
80+ Gold
80+ Platinum
80+ Titanium
Bronze is pretty much the lowest recommended with Gold being that defacto sweet spot.
It's not well built either, and costs more than a better supply with better quality like the CXM 550.
It'a also non modular and again, for the price that is not gonna fly.
However, while I've personally never had an issue with a CXM power supply, myself and many others are aware that they aren't super great and do have a tendency to fail from time to time and if you unlucky it will fail while using it, and will take out a key component in your system with it.
So if you want something a little better and are willing to pay a few bucks more than what it would've cost for that cooler master I recommend to you the new Seasonic FOCUS series.
This is the Seasonic FOCUS Gold 550W Semi Modular PSU.
It's 80+ Gold rated, 550W, Semi-Modular and has fantastic build quality and reliability.

For the about $2 less though, you can go fully modular with a slightly older model PSU from Seasonic that is the same wattage but 80+ Bronze rated.
The key difference though is that it is fully modular instead of semi modular but still has fantastic build quality and reliability.

In the end, it's your choice.
