So i just bought a Ryzen 3 1300x, MSI B350M gaming pro motherboard, Samsung 850 EVO SSD and a 2 TB hard drive. I plan to buy a GTX 1050 ti,16 gb of DDR4 3000 and a NZXT S340 case but the thing that i'm having trouble with is picking an appropriate PSU. I've gathered a fair amount of knowledge on this matter but am concerned about picking the wrong one.I think a 500w PSU would be enough but i dont know. Help would be much appreciated. I also wanted to maybe put in an led strip and/or RGB case fans but don't know if that would influence what PSU I would buy. This is my first PC build by the way so, sorry if my part list looks stupid. I think that covers everything thanks in advance.
