Why presume when I literally said they both are supposed to have the exact same internals?

Because they're not, it's you presuming things out of thin air. Corsair RMi uses same platform as HXi, the difference is only in the components that make up for efficiency level. And even if RMi did have the same internals as RMx, only to have multi-rail also which is sole requirement for tier A+, then it would therefore qualify for it.

Edit: old 2015 RMx are indeed used simplified HXi platform, without multirail. Can't find the quote but HXi uses custom designed platform and despite simplifications it's still were too expensive to manufacture so Corsair adopted more mass-produced platform for 2018 RMx. Reviews showed that it's still very good unit and Aris actually thinks that it's better than old one, although JG begs to differ (Corsair RnD head strangely enough).

Edit: found it :

and if the rmx would be a multirail, i would've placed it in tier a+

Hello everyone,

 

I want to buy a psu gold and then my choice is between super flower leadex III 550w and thermaltake toughpower gf1 650w. I was gonna buy it online and the delivery cost really expensive for super flower but i have discount for thermaltake delivery cost so the total price is same between this product. question is what you guys will choose if you in my condition?

 

Sorry for bad english

[Danny Proud]

What about Silver Green of Super Flower is it bad? can it run a i7 3rd gen wth rx 580?

Aris says they both perform about the same in every other aspect except noise and features  , where the v2 has the advantage in noise levels (due to having a a PIC microcontroller that allows for a slower rotational speed for the fans) and the 2 EPS connectors is now available in the v2 750w variant and not just exclusive to 850w variant as it was with the V1

 Johnny says the build quality of the first version is better  but also said that it wont make a difference  to the end user , from which i can presume that what he meant is that the older platform had better build quality because it was initially designed to accommodate for more components  for higher tiered PSU's with platinum efficiency and well configured multirail. but not really beneficial to the user because that high build quality is not really needed  for a unit like the RMX

Why is the seasonic gold fx focus plus so bad?

Old revisions (2017-2018) will shut off on some GPUs (970, 1080 ti, vega 64, 2080 ti). it'll will trigger the overpower protection, and will shut down immediately.

 

New revisions (2018-2019) have a bigger headroom, but aren't built for it and start to ripple at the loads where the PSU would shut down at with the older revision.

 

it's mostly due to the last revision it came out so low

does the gigabyte P650H exist? or is an error and should say P650B?

Your opinion is based on several negative opinions of early revisions of Focus plus. Several negative opinions out of tens of thousands satisfied with this power supply and hundreds of good reviews doesn't mean it's a bad unit. I myself have this psu connected with 8700K 1080ti both oc and in future with 2080ti or 3080ti and i don't see any problems, also reccomended it to many other people. If you go this way of thinking, you can find negative reviews about each power supply and say that they are dangerous. 

This list is strange, starting with favoritizing multirail and ending with putting very good units in the last tiers.

Oh, so you're clairvoyant ?

Neither it means that it's a good unit. Search at least on this forum alone and you'll find several threads with people complaining about GPU instability with Seasonic Focus, even with upgraded shielded cables. Even Seasonic themselves acknowledged the issue.

Yeah, because it's better to have more protection, right ? Or nah ? Or Seasonic PSUs should be in the top tier regardless of anything just because they're Seasonic ?

Everything are tiered according to methodology. Units that have ended up in tier D+ have some flaws, see sources on them for more info. With otherwise plenty of options there are no reason to buy PSUs that may even potentially give you problems, just buy some other PSU besides your precious Seasonic\EVGA (or get Seasonic Prime which is good).

Nope.  Wrong.  It's called reviews of the Focus plus not just by avg joe-end-user having issues now, but also pros who reviewed it and found that Seasonic failed to completely fix the inherent design issues with that series of Focus.  Seasonic tried to fix the issues and they just turned "shuts off on high GPU pull" into "ripples out of control" which is not a smart thing to let a PSU do.

 

There are so many many other fish in the sea that the consumer is not HARMED by avoiding this problem-prone line of PSU.  They are better off getting a Corsair CX or RM or any other number of PSU that don't have faults  ... the end?

no, it's based off testing on good tools, not just some system and hwinfo or something

that's why i only factor in ones from professionals

what's wrong with multirail? it used to even be part of atx specification. prove me that a well implemented multirail has downsides, because no-one, including seasonic themselves have been able to prove me so

because i have reasons that have put the g3 and focus in tier d+? because i rate bombs tier e?

technically only the first revision, the second hasn't been officially, but they did fix it in the 2019 revisions as far as testing has shown so far

interesting, but my wallet says hell no

 

though for a 600 dollar tester... not bad

You could get an oscilloscope and multimeter for that price... That could potentially be easier and more accurate. Just add some cables to the end of the PCIe/EPS connectors for 12V, and you're pretty set. Of course, you won't get the fancy timing stuffs, though.

Where you can put Corsair TX 750 non modular

which one ? the V1 or the V2 , both are a decade old design 

[Velcade]

Where do the Prime Ultra Platinum stack up on the list? I don't see them.

 

Thanks!

They're in Tier A, because they're single rail.

From what I remember the V1 is a old group reg design: Tier C/D.

 

V2 is M12II EVO rebrand: ~Tier B.

corsair txm doesn't seem to have ocp on 12v

https://www.tomshardware.com/reviews/corsair-tx750m-psu,5062-6.html

so maybe b+? or you mean ocp on the minor rails only?

Quote

Over Current Protection (OCP): The single +12V rail PSUs usually don’t have OCP on this rail, but they should have OCP on the minor rails, including 5VSB

the importance of OCP for 12V  in single rail PSU is diminished by other protections (OPP and UVP), but when we are talking about multirail its a different story as they protect against other scenarios that won't trigger other protections
