LinX and IBT are not examples of this, being LINPACK based benchmarks/stress tests that are based on a library developed in the 70s. I don't know much about the internal workings of Prime95 or SuperPI, but I doubt they qualify either. If you think that Intel doesn't take into account some of the most common stress testing tools out there, then I'm afraid you're beyond my help.



Not all of the current is consumed. Some current used in the base charge is not dissipated as heat. I don't know the details, CPU architecture and design not being my specialty, so I'm a little out of my comfort zone there.

You could think of it like this- If you have a sprinkler system that is super efficent. The plants will take what they need (heat) and the rest that isn't used is returned for something else via the ground for singling and whatnot.

Out of my comfort zone but I think that is a simplified, simplifed version from what I understand (which isn't much).

I don't know the key words to put into google, but if I knew, I would be reading about it right now. This kind of stuff interests me like candy to a fat kid.

Look unless a degreed EE wants to weigh in on whatever I might be wrong compared to what your wrong about, I'm done.

You should know that peak and maximum mean the same thing. And peak draws do count as electrical requirements.

You could talk about it with zero actual knowledge, lol.

This is where you show the most lack of knowledge. The cpu needs 70w for 1ms but the PS gives only say 60w, what happens then? Well, 1ms is thousands of thousands of CPU cycles... See we measure cpu in Gigahertz now. Even 1 microsecond is thousands of cpu cycles.


While the OP has long been bored to death you and tatertot theory that you should/or can run a 65w tdp processor and ~30-40w of computer of a 60w power brick is silly beyond compare.

^ this.

Hey, I don't know what's up with Tator talking about a 60W power brick for this. I said so much earlier. I'm not talking about that.


You have no understanding of how power circuitry works and I doubt you'd know a buck converter from a flyback without it being labeled in 72pt font. Any well designed power supply can handle brief peak loads above its rated continuous output power. It's not a concern, unless the peaks are of a large magnitude, or high frequency.

This system would be fine with a 120W PicoPSU+power brick.
(again, don't know why Tator said a 60W power brick)
post #37 of 40
PicoPSU's come with a 60w power brick, but the 60w means nothing, they can do the 120w once all is said and done.

Without going into a long argument of it; why not just email Mini Box and ask them why they include a 60w adapter with a 120w PicoPSU. They'll be glad to explain it as they design the things.

Either way, 60w brick works fine; otherwise they wouldn't include int.

Ha,

So basically your admitting that a CPU with TDP of 65w should be allotted 65w and the brick is over rated by 2x (sustained of course).

If that's not what your saying please do clarify.

Fine, suppose I don't believe the same intel spec sheet that says intel processors can consume over their TDP specs in peak and sustained wattage.

I need you to tell me exactly how much, a 2500k 95w TDP, can draw. You stated that its commonly accepted industry knowledge, apparently I'm not privy to.

It's even better if you back it up, because hey your just a guy on the internet and intel is well they are smarter than you.


We are assuming the cpu is stock everything and in the to 5% of power consumption for that model. To make your life even easier lets only consider sustained power draw.

Where did I say anything that like?

I'm saying that if you want the electrical explanation as to why a 60w brick can power a 120w PicoPSU to email Mini Box for it.

With that said, this conversation just goes back and forth.
