Build Advice PC part compatibility check. Any suggestions?

Dec 2, 2019
This is my first time building a PC from scratch. So do review and help me not waste my money! Thank you.

These are the parts I mean to buy:
These are the parts I already have:

I understand 1060 is a bit weak in comparison to Ryzen 5 3600x, and that there's a chance of bottlenecking, but I do not have the budget right now. I can get an RTX 2060 in a month or two though. Would anything drastic happen in these two months? I want the PC mainly for gaming and also a little rendering in Adobe Premiere.

Does this motherboard support these two SSDs? I don't know much about M.2. All I know is that there are two M.2 slots, but there was THIS THREAD which worried me a bit...

is Corsair VENGEANCE LPX 16GB 8GBx2 3200MHz CL16 compatible? Or should I go with 4GB*4?!

Is the power supplier sufficient? Or is 550W too little?

Please help me get this build done right! Thank you.

I would go more along this route. First you get more SSD capacity for less money and you will not notice any difference in performance. Secondly the PSU is far better than the one you are looking at with the CoolerMaster Elite v2. Third $399 for a 1060 6GB is a ripoff.
