I strongly recommend you to get a higherr wattage PSU than extremely high quality one. Don't worry about XFX's quality, its good enough. EVGA 650G is very high quality too.
PS: XFX is made by SeaSonic.
The PSU is extremely high quality, but the GPU with other hardware will really be pushing it to its limits, upgrade recommended. The system has 42A on 12V recommended but the demand is too high for safe and sound long term usage. Have you considered the 150W TDP and more powerful GTX 970?
Fair enough, as said, even though it'd be pushing it, you should be fine for atleast sometime, but do upgrade the PSU as soon as you have the resources
