First build in a long time...

[Ricko0]

I just bought a Cooler Master masterbox-mb530p, and an Asrock Taichi X470 Board. Hopefully BIOS 3.4.0 will support a Ryzen 5 3600 out of the box like Asrock's website says it will, but that's another story... My question is this.. Aside from the RGB and USB cables, the only I/O is Power SW and HDD LED. Are the ground pins on the board header no longer needed? There is (0) Zero documentation that came with the case, and I haven't been able to find anything helpful on Youtube. Any help would be appreciated.

x470 boards will support new Ryzen without issues.

 

I suggest flipping through your Mobo manual until you find the page regarding the front IO connections, every manual has one. Just follow the instructions there and plug the connectors into whichever pin it tells you to.

 

p.s. since front IO connectors are usually 1 pin, or 1x2 etc, it doesnt matter which way they are facing, as long as they connect to the right pins (but if you're not a maniac you'll make all the words face up.)

haha.. I wish it were that easy. I've been working on computers for a while, and I know how things normally work. For instance,on this rig, all the connectors are there from the I/O on the case. That's why this has me so befuddled. The Asrock board has a 9 pin header (PLED +/-, Pwrbutton,ground, HD LED +/-, Ground, Reset, Ground) and as I said in the OP, the Cooler Master case has 1 connector for Power SW, and 1 for HD LED. There's a SATA power connector, but I'm assuming that is just for the RGB controller
