Should be just fine.

Yes should be fine. If you are not sure you can use the Be Quite PSU-Calculator.

The warning message occurs when there's no fan rpm detected. You can turn this setting off in the bios. 

I was about to post the same question. I am on the same boat. I have a z97 mobo as well. o recently bought a deepcool captain 240 ex rgb and rgb fans. putting them in a fractal r6. would love for specific hardware needed to make rgb work on z97. not sure if I'm hijacking you post, but we both need the same advice. I didn't want to dupe topics.

If you are going to OC, I'm using a R7 2700X and can reach 4.2 GHz at 1.35V. Just remember not all CPU'S can do this. But for a R5 2600X, you should easily hit 4 GHz at 1.35V and 4.2 GHz at the same voltage if you won the silicon lottery. 

It should be perfectly fine but maybe put a slight overclock on the ryzen (4.0-4.2) and put an xmp profile maybe around the 3000mhz. if you want to go all out slightly overclock the gpu too.
 

it all depends on what games you gonna play,i have both 1700x(4.0) and 8600k(4.8) ryzen will bottleneck (<60fps)(at 1440p on a rx580!) on many games like PUBG(its better than it used to be tho,Stellaris,any mmo except warframe. any Total war game and others... 

im not saying intel wont bottleneck caus my intel is bottlenecking on No mans sky @50-60fps ....but if you want to make sure you got the best machine to combat bad optimized games you gotta go Intel and Nvidia... especially if you are looking to play  sandbox games ,or games that are beta/alpha etc from steam i.e. Unreal engine games.
