switching-PSUs: why can't you usually exceed the 50% of declared power?

It's not LTT. As of information, it's good enough for general public. When Corsair gets mentioned every time, what did you expect in their own video, duh.

Actually it's kinda sad.

What's sad? It's video on Corsair youtube channel :palm:. What did you expect?

I was talking about him and his channel, in general. As well as all the other tech youtubers who have given up and cater to those who have the attention span of a mosquito and only want to be entertained.
But I get it, you're just looking for mud to throw.

You watch infomercial on youtube channel of company that sells PSUs. Then make some dumb comment about it. WTF do you expect from infomercial?

And those reasons would be?

Let me put it another way. Some people may end up buying high efficiency power supplies because they want a particular power supply for other reasons, such as overall quality or features, and in the process end up with a high efficiency PSU. I can only speak definitively for myself, so the two times I can remember offhand that I went for a high-efficiency unit, what I was really after was quiet and cool, for HTPC applications. In one, I used a 600W semi-fanless (no fan until half power) unit with very high efficiency (don't remember the number) in an application that maxes out a bit over 200W. It also lightens the load a bit on the UPS I suppose, but that's a minor consideration. I don't care about the power bill.
I think most high-quality units today will also be relatively high efficiency, although perhaps not the other way around. Can you think of a counter-example, a high-quality low-efficiency PSU? I can't.
