So we will need this with 7000 series AMD?

We have to wait until early November to see what AMD offers with RDNA3 discrete graphics. Speculate now if you want but in the end it depends on AMD’s actual announcement.

AMD has made hazy claims of improved performance per watt metrics versus RDNA2 but this doesn’t automatically determine final board power.

That said, I doubt it. If AMD releases power-hungry cards with a 12 pin or 12+4 pin connector, they will likely include a small pigtail adapter just like NVIDIA did with their high-end Founders Edition cards from the Ampere generation. There's also the possibility that AMD AIB partners will use the legacy 8-pin PCIe power connectors on their custom PCB designs.

Currently building a new PC and was looking forward the 1000W G from them. unfortunately mid-december seems a bit too late... I was kind of hoping it would be available before that timeframe. Might have to go with MSI A-G 1000 PCI 5.0... Any opinion on MSI PSU? Seems they are OEM from CWT not too sure if that's a good sign or not?

Titanium spec PSUs don’t seem to be released anymore. Have makers decided the difference with platinum efficiency isn’t worth it?

Your best course of action would be to wait for detailed analyses from competent third party PSU reviewers. The average tech forum participant (here at TPU and elsewhere) has zero hands on experience with these newly announced products.

And most of us don’t test multiple units side by side anyhow. The only thing that we can really say is that a PSU works reliably (or it doesn‘t).

It would appear so, though perhaps Titanium is harder to hit with the transient spikes in ATX 3.0? It certainly seems an evolution of 80+ is in order now that "greater than 100%" is a baked in function of power supplies.

Titanium spec PSUs are a very niche category, more of interest for servers and industrial uses than mixed use consumer deployments.

It’s not like a Titanium PSU will give more fps or help your Excel spreadsheet. I'm not seeing it and I own one. The primary benefits of Titanium spec PSUs are efficiency at the extremes of the load curve (idle load and full load near PSU maximum capacity).

I doubt it. All GPU's still use 12v DC power. The 1 "new" feature of these PSU's compared to other Seasonic lines is:

• Added 12VHPWR cable to comply with the new graphic cards

The Nvidia adapter of the 4xxx series is just a 4x8 pin to 12VHPWR adapter. If any AMD cards do use the 12VHPWR, I'd expect them to also include an adapter.

If you use this PSU you just won't need to use the included PCIe adapter.

Come on dude....

ATX3.0 brings quite a few things to PSUs. Is it needed, maybe not to run new GPUs, but nonetheless its coming and will become the new standard. The new cable isnt the only thing:

• Up to 3x GPU Power Excursion
• New 12VHPWR connector to up to 600W
• 12V rail can ramp to 12.2V allowing for lower voltage drops
• 2.5 - 5x times higher slew rates for transient loads on the +12V rail (the rate at which the output voltage and output current changes)
• PSU signals power capabilities to PCIe to enable power limitations on components such as GPUs and SSDs
• Minimum of 175,200 power cycles
• Greater than 60% efficiency for 10W load (or 2% of max-rated capacity and above 70% efficiency).
• Rated for up to 200% of rated power for 100μs (with a 10% duty cycle).
• Faster system wake up & Power On signal
• ALPM to replace ASM

Hopefully it's much better than their focus platform......................I didn't have much luck with it.

He probably didn't bother to read the spec/change log.

ATX 3.0.............................it's about time. Only thing is there is a few 'optional' features. Only thorough reviews will probably catch. It would be nice if manufacturer's would be honest and transparent about all the parts (including optional) ones they are complying with.

You are correct. Not saying you're wrong, but wanted to clarify some things....

1. 3x power excursion is PCIe 5.0. Not ATX 3.0.
2. The 12VHPWR connector is optional. That's PCIe 5.0. Not ATX 3.0.
3. This is good as it allows manufacturers to make PSUs that are less robust than better PSUs already on the market.
4. Most decent PSUs already support this slew rate. They're just making it better defined.
5. Except for that's not how Nvidia actually implemented it. Again, this was defined by PCI-SIG after consortium members got their hands on the connector Nvidia wanted to use. The CARD_PWR_STABLE and CARD_CBL_PRES# are not used and the two sense wires are simply shorted to ground. This part of the spec was largely ignored by Nvidia and PSU manufacturers because proper implementation would require an IC, which would add to cost. And development time that would stretch out well beyond 9 months.
8. This is for support of Modern Standby Mode (I know.. ALPM... It's was called MSM in development and since I was working with Intel on it, that term sort of stuck in my head. Like calling FedEx stores "Kinko's" and the place where the Lightning play "The Ice Palace") and most better PSUs already support this.
7. This was defined way back in ATX DG 1.4 in order to put a specification in writing to support the CEC efficiency requirements for S.I.s shipping into certain states and most better PSUs already support this (utilization of LLC controller that supports a burst mode). On that subject.. WTH with Intel's document numbering? ATX12V up to 2.53. Then that's replaced with ATX 1.3, 1.41 then 1.42, then they go to 3.0. LOL!
8. This is the difficult part and a reason why a lot of those PSUs you see today that literally just slapped a 12VHPWR connector on the PSU housing have failed testing... because they didn't bother to test for the 2x power excursion.
9. This was defined way back in ATX DG 1.4 and most better PSUs already support this (updated supervisor IC).
10. This was defined way back in ATX DG 1.4 and most better PSUs already support this (updated supervisor IC)

If you use this PSU you just won't need to use the included PCIe adapter.

The reason this is taking Seasonic until December to launch is because of the one aspect of ATX 3.0 that's especially difficult to address: The 2x power excursion.

Intel decided to base power excursion requirements not on hardware, but on the PSU itself. It has expectations that a PSU can support 2x it's capability for 100μs (which is easier than the lower excursions because it's so fast and as the excursion reaches the PSU's actual rated output capability, the time increases). That means a 1200W PSU needs to support up to a 2400W power excursion. That's not an easy task and why every one of those PSUs that popped up with a 12VHPWR connector slapped on it the week after that ATX 3.0 spec came out completely fails testing if you test it to that aspect of the spec.

That said... that aspect of the spec is complete horse shit. Intel saw it like this: "Ok. If you bought a 1200W power supply, that must mean you have a 600W GPU, a 300W CPU and a 300W rest of system... there fore, your power excursion calculation is 2400W."

That's why, for time to market sake, when Seasonic launched the TX-1600 as "ATX 3.0 ready"... they were already mostly ATX 3.0 ready because of the pre-existing DG 1.4 document. The only thing they were missing was the 2x power excursions. So, to address that, they put a footnote on the box that states that the PSU is "only ATX 3.0 ready up to 1000W." By stating this, they only have to commit to a 2000W power excursion, which is pretty reasonable for a 1600W PSU.

Sure, my reply was mostly to point out that the new GPU's & CPU/Motherboards, without a doubt will not be requiring it (they can still use 'out of spec' 12VHPWR connectors, like Nvidia cards do already). Maybe we see some adaption next gen, but I wouldn't be surprised if we don't see ATX 3.0 widely adapted until the 9xxx AMD, 6xxx Nvidia & 15xxx Intel platforms.

I hope AIBs will just use the old connectors for 4070s and below.

It is the time for me to replace my 2014 Seasonic X series with this one.

thermaltake GF3 and now seasonic vertex dont include 650w in their initial lineup. is it because its harder to make or no plan for now to make ATX 3.0-capable 650w ?
not really want to spend 150$ to buy another overspecc PSU.

Hey if possible can you make a list of available atx 3.0 and pcie 5.0 power psus that are available now there seems to be a lot of these in the pipeline, but who buys a psu months after their gpu? A powerless gpu .

Probably because they couldn't see someone using a 650W PSU with a Lovelace card.

Why make something that almost nobody will buy?

I wished these companies had a retrofit service for previous generation psu instead of contributing to more e-waste.

I hope thay will offer type 4 cables for the 12 pin from vga psu output.

gold is pointless price for plat are virtually same in all but useless 1200w version lol

Just re-read that pic........................fully compatible with ATX 3.0 and PCIe 5.0.

To me that does not mean meets or exceeds all mandatory and all optional requirements of the ATX 3.0 specification.

No to actually have the smart features module so that the old psus can communicate with the gpu not just retrofit the cable the whole psu. Or at least have a recycle program where they eat the cost of the shipping to mitigate ewaste. The current news with those retrofit cables pose a burn risk and or ware out after 30 plug in cycles. Can all atx 2.0 PSU handle 450 to 600 watts from one rail? To Corsairs credit they do guarantee compatibility with their 1000 to 1600 watt psus.
