A high school text book, that's probably not changed in 20 years, isn't the same as the curriculum you'd be likely to be learning at the collegiate level anyhow, so I'm not sure how that's relevant. High school level students are usually only trying to grasp basic concepts, in most cases, whereas at the college level you're training for a field/career by professors and retired journeyman.
 
True true but some of those professors themselves were taught by other professors who were taught by professors who could have been corrupted possibly by these high school text books.

darkbreeze, I think in this instance, there is no excuse for these textbooks having the information completely wrong. Some of these things are nitpicky, but others such as the electrons moving at the speed of light are just flat-out incorrect. We're talking about high school students here, not kindergartners.

One of my favorite quotes: "It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known, but to question it. " - Jacob Bronowski

My current physics course I'm in glides over the concepts. Explains them in the most mediocre kindergarten way, then it's all just about knowing the stupid equations.
 
Being that I've had to clean this thread up on multiple occasions let's keep the discussion to power supplies please.

Electrical theory ---------> Over here

Power supplies <---------- Over here

Now back to your regularly scheduled programming.

Literally the first sentence aside from the cover and legal fluff:
While a resonant LLC converter has several desired features such as high efficiency, low EMI and high
power density, the design of a resonant converter is an involved task, and requires more effort for
optimization compared to PWM converters.

Next paragraph:
In a simplistic discussion, the switching
bridge generates a square waveform to excite the LLC resonant tank, which will output a resonant sinusoidal
current that gets scaled and rectified by the transformer and rectifier circuit, the output capacitor filters the
rectified ac current and outputs a DC voltage.

It's a way to drive the primary side of a switchmode power supply.

Why shouldn't I expect you to read a few pages?
 


Eh, they just aren't educated on PSUs, so it's tough for them to listen to a bunch of forum users babbling about replacing his PSU, even though he should.
 


how can he stay so stupid , am i getting trolled again?
 
No. Some people are just too obstinate to listen to advice, even when it's accurate and in their best interests. Nothing you can do when that happens. Even if the unit were to blow up, he'd insist it was because WE said it was going to, not because it was garbage to start with.
 
at the moment i got a. 650w gs for my r9 380 and i5 6600 non k on my h170 mobo.
howeverrrr i want the absolute best unit (because i want to) so guys whats the best 500-550w unit.
i think myself the seasonic platinum 520w fanless?

also... i think pascal/polaris gpus will use less power?
 
Yes Seasonic Platinum fanless units are the near the top of the top of the highest quality units in my opinion. Silverstone Nightjar 520W is the unit you want - it's the same thing, but usually cheaper and nicer looking.

Costs a crap ton though. The normal platinum units with the fans are also fantastic.
 
Personally, if I wanted a unit between 550-650w, this would be the unit I'd get.

It scores a 9.8 at the JG, and is an amazingly good unit for the price, or at any price for that matter. FAR better than that GS. This unit has some of the best ripple and voltage regulation results you'll see on any currently made PSU.
 
^_^ I'm a seasonic 1000watts sp platinum user bought last june 25, 2014..... Until now dont have any complain about this psu, works great and worthy with 7 years total warranty (Y).... 90% efficient very useful to me, electricity bill down after i replace my vs650 corsair for this psu,i save around 15% of my total bill... (Y)
 
I'm currently running LC-Power 600W LC420H but someone told me on this forums it is no good at all. Can someone tell me if CoolerMaster 600W B2 B600 is any good? Because I'm getting weird crashes and the same guy said it was the PSU since it isn't good.
 


Look here http://www.jonnyguru.com/forums/showthread.php?t=12284 it's a low end unit. If you are thinking of buying it, don't. If you already own it, the power supply is probably not your problem, since it'd be your second one with persistent freezing.
 
Treat that G750M as a 650W PSU otherwise it may have issues. Your tier-5 LC-Power PSU-shaped object may be good for 350W-400W, so you could probably get a tier 1-2 500W-550W PSU for what the G750M costs and it would be enough.
