Finally a review of a GAMDIAS Power Supply, it has killer performance

[dirtyferret]

Yes, the RGB performance of the Kratos M1-750W is killer. The PSU of a more than decade old platform is completely mediocre at best but good for Andyson getting some more business as I haven't seen to many raidmaxx PSU and was worried about them.

GAMDIAS Kratos M1-750W PSU Review

Offers flashy RGB lighting and bold aesthetics but falls short in performance and efficiency

It's still a group regulated design.... so basically not really recommended for any modern platform.
I have no issue with a PSU that uses older regulation methods for the rails (i.e. independent regulation (e.g. https://www.techpowerup.com/review/ocz-zs-650w/4.html) and not DC-DC) but this is far from that.

For the money there are better options - I'd avoid this. And I'm sure Andyson as an OEM can do better - I do still wonder why some of these OEMs still make lower end platforms... I guess business is business but that can harm your reputation down the line.

DC - DC on the 12v, group on the others but still an older platform

The vast majority of people looking for a PSU have never heard of Anydson, Chicony, Great Wall, etc., but they have heard of Aerocool, Cooler Master and Corsair so I don't think they are worried about their reputation taking a hit on a junky unit.

Your title mention of "killer performance" is contradicted by your own statement that it is "completely mediocre at best" and the article you link that summarizes it as "falling short in performance and efficiency".

It kind of has to be - 80+ bronze with a purely passive regulated design would be harder to do.
The irony is the article links it to a 10+ year old Antec HCG PSU as using the same platform, but that the newer one has been improved modernised... but the older Antec PSU had independent regulation of the rails and better output characteristics - from what I can find out that was actually a Delta OEM PSU. Other/older Antec HCG PSUs which were group regulated were Seasonic OEM.
Looking at the two, there are similarities (input / APFC stages) - maybe the design is part shared or copied but definitely inferior end result.

Also I don't get this:

On the secondary side, we can see the four power transistors that generate the DC rails, three forming the 12V/5V lines and an independent circuitry for the 3.3V line. This is the first unit in several years that we have seen without DC-to-DC circuitry on the secondary side. The 3.3V and 5V lines are generated via a group regulation scheme, with the controller monitoring the 12V and 5V lines as one.

How do you group regulate 3.3V&5V if the 5V&12V rails share their output stage...?

The vast majority of people looking for a PSU have never heard of Anydson, Chicony, Great Wall, etc., but they have heard of Aerocool, Cooler Master and Corsair so I don't think they are worried about their reputation taking a hit on a junky unit.

That is true, and they will also start their purchase by sorting the list by price low>high - can't be helped.

Anyway, staying on point, unless you need RGB, there are better options... maybe even with RGB...

I said

not that the platform performance is killer

How do you group regulate 3.3V&5V

He says "The 3.3V and 5V lines are generated via a group regulation scheme" which probably means 3.3V rail is regulated by a magnetic-amplifier post regulator from 5V hence the "Cross-loading the unit also causes the minor lines to fluctuate heavily, a distinct feature of all group-regulated platforms"

Sometimes making a joke around here is harder than it's worth.
