Question Help find Cybenetics report for be quiet! Straight Power 12

[Elliah246]

Can't find it. Does it exist? If so please share! Thank you!

See the botton line?
Efficiency With 10W or 2% Load = 68.664%

Cybenetics Test - be quiet! Power Zone 2 1000W

Seems to me that you've already found it (and came back to add it in)

Nope, if you read the title it says straight power 12, but the link i added is for the power zone 2.

If you didn't find it there then it does not exist there. Contact them directly and ask.

Just found it very strange that a PSU with 80 PLUS Titanium/Platinum certification has only 68% efficency under 2% load.
Considering that many times pc users just browse the web like right now, the browser is opened and a forum is being viewed, this is a low load situation. So the efficency in this case would be BELOW 80%, hmm.

The thing is the labels for be quiet PSUs, i mean the naming scheme seems to be different from the names presented on bequiets official website. So the PSU might be in the list but with a different name, for me its very difficult figuring this out. I thought someone here in this literal hardware forum might have a clue.

This is where it behooves you to learn how power supplies work. Efficiency is at its lowest when unloaded or very lightly loaded and goes up with increasing load.

Why does PSU efficiency increase when load increases and decrease when load decreases?
Is it difficult for PSU manufacturers to create PSUs with good efficiency combined with low load or is this an outcome of lazyness?

That's simply how things work in the real world.

Physics.

Just like a car.
"gas mileage" is insanely bad when the car is idling, not moving. 0 mpg.
Start moving, and gas mileage improves.

Time for plumbing analogies:

Imagine I made a water pump designed to push 100L per second, and only asked it to do 2L per second. Would it use more or less power than a pump designed to push 10L per second doing the same job?

I just asked why the situation is what it is not how it is.

I see where you're going. Nice one.

Don't make me regret asking yikes
