List of most outdated PSU 2022 regarding Intel ATX compliance

[kiriakost]

Generally speaking at the current calendar and day, INTEL ATX 2.4 this is now old standard, and any PSU still based to it, this is ancient electronic design.

I did spot so far:
ZALMAN branded PSU all ATX 2.4 ( Korea this buying from China)
SilverStone branded PSU all ATX 2.4 (Taiwan this buying from China)
Seasonic (2020~2022) ATX 2.4 ? (ODM)


If you have similar finds ? Then help the list to grow

 

[SL2]

Here are 1487 models, of which 161 are ATX 2.5 or newer.

89 % of all models are ATX 2.4 or older (models with unknown standard included).

4 Corsair models are ATX 2.5, the rest (71) are older.
You can add Seasonic to the list, they're all ATX 2.4 or older.

I haven't checked any of their sites.

I have personally checked Seasonic, they seem to be gently unclear about it, I did direct question at Facebook, they have ignore it so far.
In the past 10 days I am trying to connect with their marketing manager, unsuccessfully so far, but the team called as Media (web site and Facebook management) this is alive.

It's not a big deal though, as it applies to sleep modes mostly. And older PSUs might still work in practice as long as DC-DC based.

I am fighting here old workarounds posted at 2014 = disable all your C ( Intel) power states from Bios, so to solve the problem.
Well, I prefer instead to ditch the dead standard and go with the new = 2.53 and fresher.

Exactly what's this issue all about? I have a couple of ATX v2.4 PSU's (Corsair and Seasonic) and neither have had any problems at all with Intel sleep states on both old and newer CPU's and under both W7, W10 and Linux Mint. They sleep and resume just fine without disabling any C-states / Speedstep.

Edit: Reading this, the only 2.4 vs 2.5 difference appears to be "Alternative Sleep Mode" (aka what Microsoft call "Modern /Connected Standby" under W10) and that's the first thing I always disable purely because I don't want my PC to be "always online, always connected" when it's supposed to be powered off. That's not a "feature" to be "upgraded" to, it's yet another security threat vector on the back of Microsoft's deluded belief that my desktop PC is some phone-less Windows Phone with a 32" screen...

I don't think anyone has the time to go searching for the links for, then downloading and reading a +100 page spec design document vs simply explaining what problems you are experiencing with standby vs 99% of PSU's on the market. Have you tried disabling "Connected Standby" and just using the normal S3? There's even a pre-made .reg file here (merge, then reboot):-

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]

"CsEnabled"=dword:00000000

Has that solved whatever issue you are having?

 

[kiriakost]

I don't think anyone has the time

Nice, you are free to move on.

Top tear brands at 650 ~ 850W these are very few.
I did succeed opening the door of Seasonic for getting further explanations.
Seasonic Marketing manager responded, but clarifications will come from the headquarters, and there is some sort of Asian holiday.

 

[BSim500]

Nice, you are free to move on.

As has everyone else because after 5 posts of you refusing to explain what the actual problem is, literally no-one's going to spend hours studying +100 page PSU design documentation then playing random guessing games on a Friday night. I genuinely hope you do fix whatever problem you are having, because my v2.4 ATX PSU's sleep & resume just fine on multiple OS's without needing to disable any C states in the BIOS.

There is not any problem that software level solutions could solve, when a hardware level device (as is the PSU), this is a programmable device due the factory which make it.
Now, Read five times the Post No1, it might help you to understand of how to spot by your self, newborn electronic designs = future proof compatibility with most INTEL platforms.

I'm responding more to your 3rd post (post #5):-

I am fighting here old workarounds posted at 2014 = disable all your C ( Intel) power states from Bios, so to solve the problem.

The only problem I've ever had with C-states vs suspend / resume was on an old Ivy Bridge motherboard (Intel 3xxx series) which resumed locked in to the highest C-state (ie, SpeedStep stopped working after a suspend-resume cycle). And that problem was due to the motherboard not the PSU, changing PSU didn't fix it, but the problem magically vanished when I changed motherboard but kept the same PSU. So PSU version numbers by themselves don't mean a single thing as far as being a magical fix for troubleshooting ongoing problems you were complaining about. Now if many people's ATX v2.4 PSU's work perfectly well but it's only yours that doesn't, then perhaps you should consider that everyone else's ATX PSU's aren't broken at all, and perhaps at least try testing your PSU on more than one motherboard?

If you want to compile a list of ATX v2.5 PSU's for "future proofing" fine, but the point is you could buy a new ATX v2.5 PSU tomorrow and still experience the same glitchy C-states you were complaining about if that problem is caused by your motherboard (which is what actually controls the C-States)...

This called as change of subject in my village.
Now I will give you a Golden tip, never ever try to start a conversation with me in public, by criticizing posted facts, or by using your own imagination.
It will never work.

Consumers should learn to deliver their hard earned money, only at the brands (with specific product models) them able to deliver today innovation at reasonable pricing.
End of the story.

^Cool story bro.

Never had a Problem from Seasonic, idgaf about what atx *.* version they are.

Never had a Problem from Seasonic, idgaf about what atx *.* version they are.

It honestly doesn't matter much, or, at all. Maybe the low-power sleep feature for the >10 year old designs that don't have the Haswell deep-sleep compatibility (and most PSU designs starting 2014-2015 support this), but even then it's only a thing if you use that anyway.

My 5950X desktop is running on a 1300 G2 that I acquired new in box around 2019 and it only began being used around late 2020 when I bought my RTX 3090. This power supply was reviewed here on TPU in August 2013, so it is probably a few revisions of the spec behind (ATX 2.31/EPS 2.92), which given this unit's design and age, was probably around the first models to be Haswell-ready.
Paraphrasing Aris back then, it can still start a truck, and it does so beautifully

 

[chrcoluk]

Well they wont throw away old stock, so in these situations sadly new products get sold which are not ideal to buy.

Probably should be discounted from a moral point of view, but from their point of view, if they sell with demand they have no reason to drop the price.

 

[kiriakost]

ATX 2.2 , ATX 2.31 , ATX 2.4 , all are related to electrical measurements, all are related to minimum required load so the PSU this to be able to recover when the motherboard is at sleep state.
Most PSU comes from brands, which are the middle man, and they have no awareness about delivering proper electrical specifications.

Here is one interesting story, personal fresh experience, two identical PSU these sold under a different logo.
Both well build ATX 2.2 (successful electronic design) , the Thermaltake one it does mention minimum load conditions, actual electrical values.
The HIPER brand, skipped to do the same.
I did succeed to confirm, thanks to Thermaltake offered information's, that with minimum load in use, the freshly refurbished HIPER by my own hands, this is now good as new.

Hiper PSU's were a bit iffy weren't they?

 

[ExcuseMeWtf]

Not any more iffy than that Thermaltake... or, say, older Corsair using exact same platform

 

[R-T-B]

I mean there are very few PSUs that support Alternative Sleep / ATX 2.53 right now. I believe @crmaris tests for it. Haven't seen any pass yet but I could have missed one. I know the common SuperFlower Leadex and Seasonic Prime platforms fail, despite being very solid platforms. No one seriously cares.

 

[kiriakost]

Hiper PSU's were a bit iffy weren't they?

The one at the right it was.
But Hiper did the unexpected, replaced any PSU which failed within warranty period, with their 780W fresh batch.
Hiper it did when away from the market, but did not leave behind unhappy customers.

 

[Ruru]

I guess my Seasonic FX-750 is as well, but how that does even matter? Do we all need to go and get a new PSU when we upgrade our systems in few years?

Hi,
I've never used sleep in anyway so I sure don't care about it.
