You need a better quality PSU than that.
The VS is NOT good.
While the VS series is of questionable quality, that really wasn't the question. The PSU is sufficient to power this rig. If you can afford it, there are much better PSUs available.
The Ryzen 7 1700 and GTX 1070 will perform well together. Don't worry about bottlenecks. Game on.
