Wow. You're getting your news in all the wrong places if you believe anything you just wrote.

GodrillaNo 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.

The GPUs do not "communicate" with the PSU. The sense pins are terminated to ground (as they were with the 8-pin PCIe). The other two pins, CARD_PWR_STABLE and CARD_CBL_PRES#, are not implemented by Nvidia, nor were they asked for by Nvidia. Members of the consortium ask to add them.

GodrillaThe current news with those retrofit cables pose a burn risk and or ware out after 30 plug in cycles.

Now you're mixing two different news "stories". First: there is no "news" about 'retrofit cables" posing a burn risk. Wccftech made up the story and then Jayz ran with it. The connectors that were burning were the 12VHPWR connectors on the PSU.

Jayz's whole video is hilarious to me. He "reports" what he read on wccftech's website, then shows parts of Steve's (GamersNexus) video that shows a slide showing a burnt 12VHPWR connector on a PSU, but doesn't even realize he's showing a picture of a burnt 12VHPWR connector on a PSU!!!!!

Read this: cultists.network/8815/melting-12vhpwr-connectors/

Second, THE 12VHPWR connector is the one being reported with 30 insertion/removal cycles!!!! Nobody said anything about the same being the case for the 8-pin (although regular mini-fit jr. connectors are also 30 cycles, an HCS connector is good for 100 cycles.)

GodrillaCan all atx 2.0 PSU handle 450 to 600 watts from one rail?

Not if it doesn't have at least 450 to 600W available on the +12V rail! LOL!

GodrillaTo Corsairs credit they do guarantee compatibility with their 1000 to 1600 watt psus.

They're not "guaranteeing compatibility with 1000 to 1600 watt PSUs." They're making suggestions on what wattage to use given you plan to use a particular TDP card.

I don't understand why people can't do real research, pull up data sheets available to the public, ask actual experts... you know... REAL journalism. Instead, they get leaks of partial material and then fill in the gaps with complete bullshit that causes a bunch of drama.

I am curious about this whole thing; say, my new GPU breaks and I want to slot in an older one, will these PSUs still be able to use the old 8-pin connectors for said old GPU? :confused:

Yes. These PSUs have both 12VHPWR connectors and 8-pin connectors on them. Just fewer of the latter.

jonnyGURUYes. These PSUs have both 12VHPWR connectors and 8-pin connectors on them. Just fewer of the latter.

Thank you for the information. ^_^

Lol thank you.

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


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!

Yes you're correct, it is a bit convoluted. I had to ref the wiki and the ATX 3.0 change log to wrap my head around it.

en.wikipedia.org/wiki/ATX#ATX12V_v2.4

[SIZE=4]ATX12V v2.3[/SIZE]

Effective March 2007. Recommended efficiency was increased to 80% (with at least 70% required) and the 12 V minimum load requirement was lowered. Higher efficiency generally results in less power consumption (and less waste heat) and the 80% recommendation brings supplies in line with new Energy Star 4.0 mandates.[25] The reduced load requirement allows compatibility with processors that draw very little power during startup.[26] The absolute over-current limit of 240 VA per rail was removed, allowing 12 V lines to provide more than 20 A per rail.[citation needed]

[SIZE=4]ATX12V v2.31[/SIZE]

This revision became effective in February 2008. It added a maximum allowed ripple/noise specification of 400 millivolts to the PWR_ON and PWR_OK signals, requires that the DC power must hold for more than 1 millisecond after the PWR_OK signal drops, clarified country-specific input line harmonic content and electromagnetic compatibility requirements, added a section about Climate Savers, updated recommended power supply configuration charts, and updated the cross-regulation graphs.

[SIZE=4]ATX12V v2.32[/SIZE]

This the unofficial name given to the later revisions of the v2.31 spec.[27]

[SIZE=4]ATX12V v2.4[/SIZE]

The ATX12V 2.4 specifications were published in April 2013. It is specified in Revision 1.31 of the 'Design Guide for Desktop Platform Form Factors', which names this as ATX12V version 2.4.[28]

[SIZE=4]ATX12V v2.51[/SIZE]

The specifications for ATXV12 2.51 were released in October 2017 and introduced support for Alternative Sleep Mode (ASM) which supersedes the traditional S3 power state. Windows 10 implements this functionality as Modern Standby.[3]

[SIZE=4]ATX12V v2.52 (assuming rev. 1.42 in atx 3.0 changelog??)[/SIZE]

The specifications for ATXV12 2.52 were released in May 2018 introduces minor changes to the standard, most notably it requires power supply manufacturers to ensure power supplies with Alternative Sleep Mode (ASM) support are able to withstand power cycles every 180 seconds (480 times per day or 175,200 per year). Power supply fans are also recommended to turn on with at least a two second delay for an improved user experience.[29]

[SIZE=4]ATX12V v2.53 (actually rev 1.43.01 in atx 3.0 changelog?!?!)[/SIZE]

The specifications for ATXV12 2.53 were released in May 2020 and constitute another minor update to the ATX standard. ATXV12 2.53 makes further recommendations on efficiency and references the Energy Star Computers Specification Version 8.0 which was finalized in April 2020.[3][30]

[SIZE=4]ATX 3.0 (actually rev. 2.0 in atx 3.0 changelog)[/SIZE]

The specifications for ATX 3.0 were released in February 2022. It includes the new 16-pin 12VHPWR connector that can deliver up to 600 W to graphics cards. These incorporate data lines for components to negotiate power capabilities with the PSU so they do not draw more power than the PSU is capable of delivering. The specification also has more strict requirements for handling spikes.

there is revisions and version and doc numbers, but like you said its weird.

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

You can order a 3 x 8-pin to 12-pin cable from CableMods. It's what I did with my build over the summer.

mechtechJust 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.

What optional parts of ATX 3.0 are worth worrying about?

Some bro that's more into selling people new PSUs than trying to reduce e-waste is leaking all of this PCIe 5.0 and ATX 3.0 bullshit. I guarantee it.

no doubt
I got a v2.52 atx a couple months ago, price was right, probably use it 10 years or until it dies.

It was kind of a rhetorical but always nice to see it confirmed by the resident business cat.

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

The Loki range are Asus's first ATX3 power supplies, and their press release states they are 80+ Titanium.
So, it leaves me wondering if they are Seasonic made just as the Asus Rog Thor PSUs were, and if so are Seasonic just tied up producing those and will have their own brand TX model a little later, or is there some exclusivity contract for a while perhaps?

The Titanium Asus ROG Thor are made by Wentai. Not Seasonic.

Ok, I hadn't looked at the Titanium variant for that model, only www.tomshardware.com/reviews/asus-rog-thor-1200w-psu,5984.html
