No, because it seems that you're talking about a dumb Linear Transformer.
Meaning AC goes in, AC goes out. And its nothing more than a big piece of metal with some wire wrapped around it. 
The only silicon device might be a diode or a FULLBRIDGE-RECTIFIER..
That also means that YOU were talking about an unregulated transformer!
That is however not how PSU work as they are very material intensive and bulky.
Needless to say that nobody does that anymore, besides specialized, very expensive Equipment. And even there they move more and more away from old Linear Transformers.
 
What you're missing is that ATX PSU are so called switch mode power supply. 
And to make it worse (for your agument); a regulated switch mode power supply.
They work by switching the input frequency. Because of that, the transformator can be way smaller and is just a part in the PSU but not the most important part, because you ignore the boost converter before the Transformer, the rectification behind it, the switching between Boost Converter and Transformer.
 
Because technology improved, efficiency rose and the "shitty" PSU are up to 88% efficient (in 230VAC). We call that bad these days!
The top ones are in the mid 90s.(Gold/Platinum PSU up to 94% or so)
 
 
Because we're talking about a regulated PSU, the difference between low load (0,1-1A) and 100% can be pretty small and top PSU are sub 1% Load Regulation and the not so good ones under 3% or around 3%....
Needless to say that the filter is also its own thing, meaning that it depends on the whole unit and, as said, has NOTHING to do with Efficiency levels.
We have lower efficiency units like the ANtec Signature from 10 Years ago, that have rather low Ripple& Noise, we have rather high, borderline spec, Ripple in 80plus Titanium PSU.
 
So the buttom line is:
IF you know your stuff, you explain it. 
Simple as that.

Efficiency is about loss. But it is important for keeping voltage at a stable level even at high loads.
 
Let me strongly disagree with that. I have personal experience with XFX 550W Bronze and it has good protection and it is fairly quite even at 75% load. Also the Gold one is good and stable as I heard from a friend's experience.

With some basic knowledge on electronics field and how circuits work you can easily find out the relevance between those things. Also by insisting so much that everything else is just shit and asking people "WHere did you get that shit?!" doesn't mean you are right especially when you don't know what knowledge and experience the person you are arguing with has in that field. I agree that it is old, but it is still better than many of "new" PSUs out there. Of course there are may options out there and perhaps better VFM but I can't talk about something that I have not personally tested or seen in action. Anyone can disagree, but that doesn't mean I am wrong and they are right.
I have tested with some modern components and it did a great job. So you doubt because you haven't tried. And that is ok.

I will not argue more with you because that sentence gives a clue that you don't have a clear view on how things work. I will just give the following definitions in simple words.
 
Efficiency: The transformer efficiency is defined as the ratio of output power (primary voltage) to input power (from socket). Efficiency is varying based on load.
 
Voltage Regulation: The voltage regulation of transformer is defined as the change in secondary terminal voltage (V2) from no-load to full load at constant primary voltage and temperature.
 
So by combining those two definitions you can see how things work.

That's a bold Statement. If you could prove it, you'd have told us why that is...
 
As higher efficiency only means lower losses. Doesn't mean better voltage regulation, better ripple suppression, better reliability. It means nothing except for less power converted to less desirable forms of energy. Efficiency and Voltage Regulation or Quality have no correlation!
 
Are you seriously claiming that this PSU:
https://www.hardwaresecrets.com/antec-signature-650-power-supply-review/2/
 
Because of efficiency is worse than that one:
https://www.hardwareinsights.com/antec-earthwatts-platinum-550-w-the-cheapest-platinum-unit/4/
 
The latter one has higher efficiency but is group regulated and made to be cheaply.
The former one is made to be awesome (and based on a server/workstation design).
 
Sorry, but the claim that Efficiency is important, is total nonsense.
 
No, but you not explaining why I'm wrong does.
If you knew what you claim you did, you'd told me where I was wrong.
But you didn't do that. 

Your claim that Efficiency is important is just not true. It just means that there are higher losses, meaning we need bigger heatsinks and eventually higher airflow.
Everything else is not dependant on the Efficiency. It is dependant on the design and what is wanted.

The only correct claim would be that there are no good quality 80plus Bronze PSU these days.
But that is not because there is a correlation between efficiency and quality.
It is because 80plus Gold has gotten so cheap that its impossible to make a good quality Bronze unit as they are more expensive than entry/mid range 80plus Gold units.
And people probably wouldn't buy a 550W Bronze unit for 70-100€ when they can get an 80plus gold unit for that money.
 
If you'd know what you'd claim, you wouldn't have said that Efficiency is important, when its not. And you'd told me where I was wrong. You did not.
 
And even Electronics Engineer like Dave Jones don't necessarily know much about Power Electronics or Power Supplys...
In one of his last Videos he didn't know what/who Teapo was, has gotten a rather crappy IIRC Thermaltake PSU for his new PC and calls 80% efficiency "reasonably high efficiency".

By todays standards thats a shitty efficiency and reasonably high is at least 85%...
 
Any proof of that?
YOu know that the Transients increased by a couple of orders of magnitudes. And that I expect the Seasonic S12G Versions I have to switch off.
 
And that's not desirable.
 
Look at Corsair TXM and Bitfenix Formula. Both are better and especially the Bitfenix less loud.
 
Yes it does, as your claim about Efficiency is not correct...
Seasonic already has Problems with their more modern Designs with modern components and released a press release for that.

Why do you think older models from like 6,5 Years ago would fare better than more modern designs??
 
As said, I'm planning on getting a VEGA 64 Card and will test the Antec Truepower Classic with that (wich is the same as yours as Seasonic does NOT allow many changes to their designs. Either you take it or you don't).

Once you figured it out it works alright. I mean you don’t really use it beyond setting the colours etc. for monitoring I use HWmonitor 

Oh sorrry, my memory had a brain fart haha!
As you can tell of my signature, OC's fine and temps are beautiful

And also note that I have the 240mm rad, you're getting the 360mm rad if you were buying the X62, so larger radiator, as well as a extra fan, so cooling should even be better.
 
Do note I have my 2700x Oc'd at 4.1GhZ running @ 1.36v
 
Also running aida64Extreme for an hour CPU temps dont go above 70c~ with some cores spiking to 76c
