Don't know if the power supply is big enough?

Here is my current build plan.

Board: ASUS Z170-A LGA 1151
CPU: Intel Core i7-6700 8M Skylake Quad-Core 3.4 GHz
Graphics card: GIGABYTE GeForce GTX 970
Ram:G.SKILL Ripjaws V Series 16GB (2 x 8GB) DDR4 2133
Power supply: EVGA SuperNOVA GS 650w fully modular ATX power
SSD: ADATA Premier Pro SP900 M.2 256GB SATA 6Gb
HHD: WD Blue 1TB Desktop Hard Disk Drive - 7200 RPM SATA 6 Gb/s

Is this big enough?

yes

The Supernova GS is made by Seasonic and is very high quality. Your system can run with a 500-550 watt unit so with 650 watts you have headroom to overclock the GPU and add more hardware upgrades if you want.

I typically recommend a minimum of a 500W PSU with any system that has a dedicated GPU. Your 650 is just fine. But if you plan to some day SLI or maybe even do some heavy overclocking. You may want to consider something bigger.
