"If you trust your PSU". If PSU is so shit it can't handle more than 75W on a PCIe power connector, then you better not use it entirely because it's so shit it'll most likely blow up by itself.
There are probably more sh!ty PSUs out there than sh!ty new motherboards. I have shown a link for a 600W PSU in one of my posts, that was costing about $20-$25. PSUs based on ancient designs with many ambers at 3.3V and 5V lines. Perfect for systems that still run Athlon XPs. Believe me, plenty of people will buy the best cpu, motherboard, ram, graphics card and when they reach the final part of their system, the PSU, they will start feeling they already spend too much money on their new set up and will go for the cheaper PSU they see available.
I believe that's why AMD chose to pull more power through the PCIe bus than the 6pin. Also as I said before, the same people making motherboards, also make RX 480 graphics cards. I wouldn't believe ASUS, Gigabyte, MSI would be willing to start selling graphics cards that they can kill their own motherboards.
This shows that they are committed to addressing user concerns, and truly care what people think about their products. Doing this driver change costs them money.
And they are paying for it. Every time they come out and say "We hear you, we are fixing it", people add one more example of AMD messing up in their list. On the other hand Nvidia keeps it's mouth SHUT, it reacts like nothing is happening, and only talks about a problem AFTER releasing a fix. If it is something they can't fix, they just don't talk much about it. That way the problems looks like normal bugs, nothing to talk about, keeping Nvidia's reputation about excellent driver support mostly intact.
AMD is like the honest little person panicking when someone is telling him he made a mistake.
Nvidia is like the politician, never admitting there is a problem, or downplaying the significance of that problem.
