4th GPU - Extra Molex Power to motherboard or not? That is the question

I decided after some suggestions from the community and because i could get one cheap, to buy a 4th GPU (GTX 1060).

I have As rock BTC H81 R2.0. I am wondering what peoples thoughts are on installing the 4th GPU (it will draw 75 to 85 watts) without plugging the extra PCI-E lane molex power connectors into the motherboard? It will be a powered riser (USB with 4 pin molex onboard).

This has been debated before and is a hotly debated topic on the internet with some saying it is dangerous to do that and some saying it is dangerous to not do it. My instinct is that is that it will probably be ok since I already have 2 1070s and a 1060 which are limited on their power draw (i.e. my cards are not power hungry) as well as the fact that the risers are powered and the card has an extra PCI-E connector (as all cards usually used for mining do).
