You are 100% correct hahaha, yes the VS450 is a TERRIBLE PSU.

Well, its group regulated...

Is it? 

Do tell.

What experience do you have?

I f you really think it's one of the worst out there, you haven't seen many PSUs in your time. 

Its definately better than some hyped units that use Nippon Caps...

But that's not hard,  about 8 years later after the introduction.

 

Still, in that price segment, here in Europe, it has 2 strong contenders:
Xilence Performance A+

be quiet System Power 9

 

Both are 230VAC only...

And both are DC-DC (400W and up).

230V only saves enough cost to go with DC to DC.

 

Problem is, you cut your volume in half shipping a 230V only product (can't sell in the Americas, Japan, Taiwan, etc.) and typically the customer in the VS market wouldn't know why they need DC to DC.

 

It's a "race to the bottom", as they say.

I got so tired of people shitting all over VS, I asked Aris to certify them on Cybenetics:  https://cybenetics.com/a/bmO/

He has the VS450 too, but hasn't completed the report yet.

great, I'm wating for the rating

people shit about everything

Yes.  Being group regulated does have its issues.  But it's hardly a bomb.

 

not a bomb, but voltages going out of spec isn't nice.

pls decide, group regulation yay or nay?

assuming you save a significant amount of money by going group regulated, "all things being equal"

Depends on how the group regulation is implemented.  Some PSUs actually don't see drastic voltage changes when crossloaded.  Some will actually wake up from a C7 sleep state.  But the general rule of thumb is to stay away from group regulation if you want reliable performance.

Group Regulation is OK if you have a constant, known load on all rails.

Problem is: We don't have that on PC.

Neither is the load constant nor known, so you have to optimize the design for what you think might be the best Compromize for the setup. 

And that is the problem, essentially...

Because if you were wrong about the load distribution, the voltage might go out of spec...

But the thing is voltages with go out of spec only from time to time, whenever that specific crosload occurs isn't it?
