Yes, they are essentially same, since they all are PSUs and designed to power the PC. Just like e.g Corsair TXm and RMx series are essentially the same, since they all are PSUs.
Ridiculous argument. There's a difference between different PSUs being PSUs 'same' because they're well, PSUs, and literally the same units being sold either without fan at all with lower rated wattage (Fanless), with 2 more useless fan modes (Airtouch), or just white casing (SnowSilent). More different models is not a bad thing, people want white PSUs, and some may like more fan modes to tinker with, but this is not 14 models, it's 5. But again, not that it matters, junk budget offerings are still there.
When it's good, what's wrong on keeping it in production and selling it?
There's a crucial difference between selling the same thing for several years, and selling the same thing under different names with minor changes and vastly different asking price.
There are 4 different PSUs bearing Corsair TX-750 label, produced by 3 different OEMs and using 4 different platforms.
You mean, over the course of 14 years ? Yes, that's true.
How on hell should end user know which of the 4 he is getting when buying TX-750?
You can't buy any of that today, so you don't have to. Only two different versions of TX-m you can buy today are 2017 and 2021 revisions, which look completely different outside.
Especially since Corsair loves to mix up their PSU lines, without letting consumers know that the platform or even OEM has been completely changed
Like, they should make an announcement when they're switching from outdated Seasonic S12II platform to better CWT one when making a different model ? They do not bear the same model number, and there are differences outside. Besides, it's a common practice to not tell the end user what's the OEM for your product, otherwise you'd get armchair engineers arguing over the internet that one product is clearly better than the other because it's made by superior Seasonic, and the other by clearly inferior, 'Chinese' CWT or Great Wall.
There is no telling if you get Great Wall or CWT unit, if you buy one
And that matters why ?
That being said, i rather buy a PSU who's platform is tried, tested and proven to be reliable, without shady dealings changing the PSU internals without a word.
Trust me, all platforms Corsair uses they've tried, tested and made sure that it's reliable. I didn't want to turn this thread into Seasonic vs Corsair, but at least while Jon is with Corsair i certainly have more faith in Corsair PSUs than in the majority of other brands, including Seasonic.
No, they are not. PRIME series are using different platform to Focus series and unless you provide credible review, stating otherwise, it's your word against mine and until then, it also remains so.
Lol, here you go :
https://nl.hardware.info/artikel/89...dingen-review-maakt-een-dure-voeding-verschil
Just two reviews, i wonder why, maybe Seasonic doesn't want people to know that they're selling Focus under Prime brand ? Also, if you go to Seasonic site, you'll see that there's a clear difference between sub 850W Prime Gold/Platinums and higher wattage ones - casing depth, which indicates that it's a Focus platform, because Prime is longer (and well, you see that it's actually Focus in those reviews above). So in the end, the only difference between lower wattage Prime GX/PX and Focus GX/PX is in the cables, Prime cables are single ended, and there are more of them. Thing is, for the price difference between them (80-100$) you can buy a full kit of custom cables of whatever shape and form you want ...
When there are no reviews of PSU, how can you rank it, in your PSU tier list, that you copy/pasted from LTT forums?
Seasonic Core series are snug in the B tier, which are "recommended for midrange systems".
That's a difficult topic, on the one hand there are no reviews, but on the other hand people are constantly asking where's the Seasonic Core position, and there's some expectation on quality of these because they look like somewhat downgraded Focus, so we put it in that position. Although that it's in normal priority is a mistake, it would be moved to low priority, because there are not enough reviews to paint a full picture about it. Same thing can be said about a lot of units there in low priority subtiers really, not all companies value reviews, some tend to completely ignore sending reviews samples out (like EVGA), we still need to somehow tier those because people are asking about them. But if you look at up-to-date version (LTT and THW versions are unlikely to be updated anymore), we've made some changes to lengthen the gap between units there are zero concrete information. For example, tier A and D units without reviews are moved one tier down, i plan to do the same for tier B and C units too. Seasonic Core likely would still be in the tier B LP tho, as it's again, assumed to be a Focus costdown, not something completely new.
Btw, there is one review of Core GC-500 and Core GC-600.
Three actually, but what i mean, there are no or close to no proper reviews, because i can hardly call those proper. But in total i think that's already enough to put it in tier B, it's a budget tier afterall.
That's you and your beliefs. I, in the other hand, can not trust a company who changes PSU internals without changing the model number, where i have 0 clue which of the many revisions of that PSU i'd be getting (looking towards Corsair and Gigabyte).
I feel like you know something about Corsair lineup i don't. Because again, all aforementioned TX/TX-m series PSUs are clearly different outside, they have three different 80+ ratings and
model numbers are clearly different too.
For example: Seasonic was the 1st who made 80+ (White) efficiency PSU. They were also the 1st who made 80+ Gold efficiency PSU. Given their small size and limited resources, that's impressive feat.
No doubt, they did have some good stuff on their hands back then, i'm not against Seasonic as a company, i'm against what they're doing today.
CWT, Great Wall, HEC - all are bigger than Seasonic, yet, they refuse to innovate.
Excuse me ? What kind of innovation do you expect exactly ? Removing the DC-DC from the main PSU casing and putting it in the appendix which they call CONNECT ? That's the thing only Seasonic could've came up with because clearly no one else can do that /s And they didn't even make it compatible with 12VO while at it, i would've understood if that was the actual intent of this useless 'innovation' ...
At this point, any 'innovations' you could make in PSUs market would only be those kinds of gimmicks, we don't need that, we just need cheaper and better designs. Seasonic might have had some lead in the industry years ago, but now anything they can offer has either a cheaper or better-for-the-price alternative from other OEMs/brands, having the same if not higher QA level.
Instead, they do the same age old thing over and over. Surely, they have the money and resources to innovate but they don't have the will.
These three OEMs have minimum about 30 different platforms on their hands total, that's without stuff we don't see on the DIY market, because CWT and Great Wall also do a lot of SI and server PSUs. But that's not a metric of the overall quality of their PSUs or some specific PSUs in question, you misunderstood me if you think that i judge brands/OEM by the amount of designs they have. I just meant to say that CWT and Great Wall have more resources and they can come up with whatever their clients want, in contrast with Seasonic. And that's why Seasonic only makes slight variations of Focus and Prime (not a bad thing necessarily) and outsources budget stuff to random unknown OEMs (bad thing, at least until reviews prove on the contrary). And on the other hand CWT and Great Wall which people usually regard as 'junk Chinese OEM' have a lot of very good designs (reference or custom), some of which even considered, not only by me, but by actual professional reviewers to be if not better but at least on par with Seasonic offerings (most of which happen to be under Corsair brand but that's just a result of Jon knowing what he wants and making sure that they receive what they want). I would repeat again, it's not about the OEM or the brand, it's about the each resulting design.
Either don't let GPU draw as much as it wants or have beefier wattage PSU, so that the GPU doesn't trip PSU's 12V rail safeguard (and shutting down the PC).
If you actually read what Jon says, it's not about OCP, it's a flaw in the design of protection circuit that inadvertently shuts down the PSU when GPU feeds more than usual noise back through v-sense. It's not strictly Seasonic's fault (even though other OEMs are seemingly aware of such possibility, some even specifically put a ferrite bead on this wire inside the PSU) but nevertheless that's the state of their current offerings. And absolute majority of PSUs from other brands/OEM don't have such problem. Besides, it's also about how Seasonic treats this issue, or rather how they don't. When they had the same problem with Focus they've at least released a statement - that's a good thing, now they're in complete silence. If you would want to draw parallels with other brands - just like Gigabyte were silent with their P-GM fiasco until GN covered it, or contrary to how Corsair covered problems with their PSUs, namely failure of thermal pads on some batches of SF and TX-m and cracked MLCCs on modular board leading to problems with PG signal on some HX/HX-i, releasing statements, providing the range of affected units and offering advanced RMA.
