Need help with fan adapters

[Flak]

So I have a corsair spec 1 case (which comes with a 120mm corsair fan.) I would like to put 4 more fans into the case, 2 140mm intake, 2 120mm exhaust, but my motherboard only has 2 fan connectors. I have selected two fan adapters that would allow me to use all of my fans. I was wondering if my specific motherboard (ASRock AB350m Pro4) can support that power draw from one port. I can't find the max power from one fan connector in the manual, so I need some help to figure this out.  Thanks!

 

TL;DR: I don't want my mobo to explode from excessive power draw.

 

Here is a list of my case, the fans, and adapters.

Depends on what you are looking for. If you are fine all case fans running at same speed, you should get powered PWM splitter/hub and connect all to PWM chassis fan header. Or use 3-way for CPU header and 2-way for chassis header. Seems like mobo has limited support for controlling 2nd chassis header.
