It should be fine for that graphics card and CPU. The only thing that might change that is if you have an extraordinary number of drives, fans, RGB/ARGB devices and/or were planning to overclock either the CPU or graphics card. If not, while it is definitely not the greatest PSU out there, it should be ok for that configuration. A better QUALITY power supply might not be a terrible idea, but as far as capacity goes, it should be ok and the 2017 model CX units are much better than their older versions. That still doesn't mean they are terrific though.
