Seasonic Launches the New PRIME PX-2200 Power Supply

[evernessince]

I had a bad power supply. To determine a power supply issue I bought another power supply unit from another brand to crosstest
For some reason some cables went loose while doing the cable management from the new power supply unit.
I crosstested with the cables from the bad power supply to see if the retention force was similar.

It's not always the user fault when new cables from the power supply unit are not in specifications.
In my case they did not had the retention force. Visually I could not see any differences. I do have the old and the new replacement cable set.

Therefore I knew the retention force was obvious defective and made a quality email claim to the psu manufacturer. I instantly got a new cable set for free.

This happened around 1.5 years ago with a brand with 5 years guarantee on psu.

It's just a matter of cables.

There are government regulations here which determines the cable type, wall socket type and so on.

I'll wait and see if AMD is smart enough to use existing cables or go with the NVIDIA plug. I would recommend AMD to not go with the NVIDIA GPU PSU Plug. I have one PSU with that plug lying around. I'm not that happy about the physical dimension of that plug

Especially important for the 12VHPWR and 12V2X6 cables given they have tighter manufacturing tolerances. There is a greater chance of manufacturing defects leading to catastrophic failure.

according to the seasonic marketing material

"The Seasonic PRIME PX-2200 is a robust power supply capable of safely powering up to four RTX 4090 graphics cards, thanks to its adherence to ATX 3.1 and PCIe 5.1 specifications. Designed for demanding applications such as artificial intelligence and other high-power workloads, this flagship unit from the PRIME series delivers top-tier performance built on high-quality components."

it's nice Seasonic makes it but it's clearly not made for PC gamers so not sure why some people seem to be up in arms about it

That PCIE 5.0 bullshit makes other marketing stupdity people also. There is no PCI Express BUS as far as i know in power supply units. Feel free to correct me with the datasheet and application notes from a well known power supply unit manufacturer like seasonic and so on. Basically fraud as there is no pci bus in it. I have one such psu, there is no possibility to physically put in my Radeon 7800XT in that psu with the 16 lanes pcie connector.

has more to do with efficiency and reliability which would impact something like a data center more than you. Obviously the bus is not on the PSU but the PSU needs to support that 5.x bus in order to have access to those full features.

I wish Seasonic refreshed their 600-1000W portfolio, since most of those PSUs don't support the newest standards.

they need to sell out that old inventory first otherwise they would be stuck with it, similar to how corsair handled the RMx although I do believe many of Seasonic's lines are now ATX 3.x

I wouldn't buy another Seasonic even if it was the only one available....

 

[msimax]

ill pick one up for my next itx build

may need to mod the case just a bit

most users are unaware of is that the cable remains the same! There is no change to the cable connecting the PSU’s 12+4 pin (or 2x 8pins) to the graphics card’s 12+4 pin header! To provide you with the whole picture, there is one difference: the naming scheme! Instead of 12VHPWR cable, it is now called 12V-2×6 cable! Crazy right? I know! It is super crazy, but it is what it is!
The connectors on the PSU and VGA sides are different, they were 12vhpwr and now they become 12v2x6 and have mechanical differences.

Why is that?

 

[phints]

Why is that?

Wonder why too, Seasonic is excellent, I've used their same 650W platinum rated ATX supply across 3 builds now for many years zero issues.

Regarding this 2.2kW PSU, well zero interest, but I'm a home user. Not running at 240VAC outlet nor would I ever do a build that needed over 500W.

 

[roccale]

Why is that?

It's the only brand I've had major problems with.
They pretend to be big but they are very small. Go to their website https://industrial.seasonic.com/contact-us/ and click on the locations, you can see that only the one in the USA is a real tiny branch.
In any case, i bought a PRIME titanium model, which from the very beginning would fail to turn on every now and then. The problem became more and more frequent, at first I didn't pay attention to it, I blamed the power strip. Then one day it suddenly turned off while surfing the internet, I smelled something burning, not too strong but it was noticeable. I tried to start it several times but I could only hear the relay, tick....tick....and nothing else. Dead.
I replaced it with a Corsair CWT platform, no problems for years.
Then I had other brands, like Antec, Enermax and now I have Super Flower.
I can only speak well of all except Seasonic, which also has a disastrous RMA and support service. I've read about people who received other faulty or defective units as replacements in RMA.
In short, I'll stay away from it as far as I'll have to deal with a PSU in the future.
My personal experience.

that's just a small office to handle distribution, marketing & sales. Not sure how many locations you think they should have in the USA

Antec

Antec has used Seasonic as an OEM in the past

Corsair CWT platform

Corsair & CWT have excellent testing facilities and CWT is huge compared to Seasonic. Also Corsair has used Seasonic as an OEM as well

My personal experience.

That's perfectly fine. I've actually had more issues with Seasonic than with CWT units (mostly coil whine) but that hasn't stopped me from buying Seasonic when the price is right

Yes I knew everything obviously otherwise I wouldn't have expressed myself. Besides that psu seasinc PRIME titanium I haven't had any other psu with seasonic platform.
Lately seasonic is becoming a bit of a meme in many groups, channels...
In any case I reposted an experience that could be useful or not.
To each his own choice.

12VHPWR is the old one. 12V-2x6 is the revised one.

12VHPWR Connector Said to be Replaced by 12V-2x6 Connector

According to Igor's Lab, who has gotten their hands on a PCI-SIG draft engineer change notice, it looks like the not entirely uncontroversial 12VHPWR connector won't be long lived. The PCI-SIG is getting ready to replace it with the 12V-2x6 connector, which will be part of the ATX 3.1 spec and...

Ah! Now that's confusing. Almost as much as USB standards are.

...I think you misunderstand something. The 8-pin end of the connector is going INTO THE PSU. Into two of those CPU/PCIe ports. Not the GPU.

Oh, you mean those cables! But how much power can you get through them? Isn't it (2x) 150 W, like with all the rest of the standard PCI-e cables? If not, and you can actually power 4 4090s with them (1.8 kW) then I get it.

It's fool proofing for people like you, so you can't plug in ALL the cables and overload the rail.

There's no point having that many rails if you can't plug them in all at once, imo.

 

[randomTPUreader]

Just hook that PSU up to one of these and you're good to go!

 

[eidairaman1]

I don't get it. There's 9 CPU/PCI-e outputs, but only 3 CPU and 4 PCI-e cables (a total of 7). Not what I'd expect from a bazillion dollar, jiggawatt PSU from Seasonic.

Excessive, Only if Crossfire worked

 

[Blurpy]

is it impossible for psu manufactures to make a psu with 120v 20amp, i would like to get a 2200w psu and my house is completely wired for 20amp
