I read about fried Asrock Pro BTC boards when people used them with powered risers but also heard claims that without powered risers only 2-3 cards would work.
I'm planning on building a rig with an Asrock Pro BTC mobo in mind with 5 cards, but with 2-3 types of video cards, with different power consumptions. So what would be the safest route to take?
Always use powered risers and if you don't understand what I just wrote, let me put it a different way..............................
ALWAYS FREAKING USE POWERED RISERS!
There!
Get it?
Got it?
Good!
My $.02.

hmmmm........and for what reason?
I got a rig running without power (Molex) to the motherboard (Asrock H81 pro BTC) without powered risers with 5 R9 280X.
