I said that this PSU is one of the cheaper lines that Coolermaster has released and we can see that already on the box. Since it’s inexpensive will it performing well? On the box you will find a picture of the PSU and the box comes in white and purple which are the familiar Coolermaster colors.

On the back of the box you can read about the various features and specifications.
