That is a dangerously low wattage on your psu. Your computer may or may not explode at any time.
I know I'm late on these comments, but I would recommend you upgrading your RAM to 16gb of ddr4. I know that 8gb is good for games nowadays, I would seriously recommend upgrading to 16gb like I said, especially for the future. Other than that the build looks good! Congrats
