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!

Not for the asrock H81 Pro BTC motherboard.  It provides supplemental molex power to the PCIe ports already, so powered risers would be redundant and likely to cause a short circuit as described in threads in the past.

What?

No, just no. Powered risers will never cause a short with the pci-e lane, no mater if the bus has supplemental power or not. 12V is 12V. 

I'd go a step further and say never use ribbon riser cables, but if I were to use those pieces they would certainly be powered. LostDuchman knows what he is talking about, use the powered ones no matter what mobo you use.
