Building my first dedicated rig, how to not blow up mobo with risers?

[VirosaGITS]

I would like to understand how it works, learn from other's experience.

I got a H81 pro btc. I was told that if i use Ribbons riser, they all need to be on PSU 1, and then i can mix GPUs on PSU 1 and PSU 2. However if i have USB powered riser, i can do mobo + 3x gpu + risers on PSU 1 and 3x gpu + usb riser on PSU.

Is that accurate? Can i mix USB and non usb risers as long as ribbons riser are on same PSU as mobo? Etc?

Does nobody knows or is it wished that i blow up my mobo?

Actually no, but it is better to have the riser in first psu cause when you power up. Everything go up at the same time. Its just better...
