Regarding XPG CORE REACTOR II 1200 WATT

[MURFING]

So I did buy myself an XPG CORE REACTOR II 1200 WATT and the package says ATX 3.0 12VHPWR yet the website of the local store that I bought from said ATX VERSION: ATX 3.0&3.1 and  ended up confused not knowing if what I had was an old unit or the new one.. Some ppl said that it's just the package is old and hasn't been updated but inside you will find the new updated cables, then I actually did find this on XPG facebook official's page okay so they saying no matter if the psu includes 12vhpwr or 12v-6x2 , still ready to connect and powerup the new 50s series? does it mean that they are aware of such a thing and trynna say that the atx 3.0 12vhpwr will still get the job done perfectly fine as much as the 12v-6x2?

 

Imma be pairing it with a 5090 nd this is why I am really worried and wanna make sure..

Comes with the cable you need in the box. 

 

I'd suggest you stop worrying about what the retailer and twitter say and just use the manufacturers website.

The 12vhpwr cable or cord should power all current nvidia cards.  A link below that explains the changes of atx 3.0 and 3.1

The changes for the 12V-2x6 were made on the graphics card connector. The 12VHPWR/12V-2x6 cable is the same.

Thank you soooo much dude I was hella worried to pair it with my 5090. So actually even if the box says and the package says ATX3.0 12VHPWR, it still has the new cable that I need? I did check the warranty and it says it is under warranty till 2034-11-30 which means the unit I do had been produced like 5 months ago so it is literally new and should have the the all new 12v-6x2 cables right? but I dunno why the box says atx 3.0 12VHPWR, tho..  and what if the PSU still has the 12VHPWR connector and not the 12vh-6x2?

literally without any issues? cuz ppl on reddit been saying that the melted 5090s got melted for using 12VHPWR connector and that atx3.1 12v-6x2 is a must and shit like that lol

and what about the connector of the PSU? what if it says 12VHPWR? I guess I am just confused.. Like I literally can pair this atx3.0 12VHPWR with the 5090 without any issues and will work as perfect as being paired with atx3.1 12v-6x2?

Nvidias connector issue is a shitshow itself. The 5090 has too stupid of a connector and draws so much power (nearly 600w) that it just does what it does

ATX 3.1 while a must it is good to have for safety but not a 1000% necessity

aha I see. if so then what about XPG statement? and what about the 5080? same issue? need atx 3.1 12v-6x2 too?

Not to the same extend but cna happen and it has other issues like missing ROPs where you can lose up to 10-12% performance (or win that much but you have to get lucky)

but I mean atx 3.1 12v-6x2 isn't needed with it, no? like what do you think of XPG statement? their 12VHPWR cable already ready to work perfectly with the 50s gen just as much as the 12vh-6x2?

You worry too much (not necesserally a bad thing) but keep asking questions in a circle ending up nowhere

People on Reddit are wrong.

The 12V-2x6 changed the PCB mounted connector (connector on the GPU) so that the sense pins are slightly shorter (1.5mm) and the power pins are slightly longer (0.25mm). This change was to move the sense pins further back so the connector has to be inserted far enough to reach the sense pins that there will be good contact between the power pins.

The Corsair help article that Silencer12 posted earlier shows it in a pretty simple way.

https://www.corsair.com/us/en/explorer/diy-builder/power-supply-units/atx-30-vs-atx-31-whats-the-difference/

 

 

The 5090 is using the 12V-2x6 connector. The reason there's been melting cables on the 5090 are because of the way the 5090 is designed. There's 6x 12V power wires in 12VHPWR/12V-2x6. On the 5090 they designed it so the connector groups them all in to one big 12V rail on the card. There's no load balancing between those 6x 12V wires. The graphics card can't tell the difference between 600W split evenly over 6 wires or 600W over a single wire. There's not a huge safety margin in 12VHPWR/12V-2x6 cables so if the current isn't properly balanced across the individual wires they can heat up and melt.

 

Ideally you would have the load balanced fairly evenly across all the cables something like:

12V₁: 8A

12V₂: 8.5A

12V₃: 8.5A

12V₄: 8A

12V₅: 8.5A

12V₆: 8.5A

Total: 50A (600W @ 12V)

 

But, with the way Nvidia designed their 50 series cards with it all going to a single 12V plane without any current balancing you could, under certain circumstances, end up with:

12V₁: 9A

12V₂: 16A

12V₃: 6A

12V₄: 5A

12V₅: 6A

12V₆: 8A

Total: 50A (600W @ 12V)

 

That 12V₂ wire is overloaded and is going to overheat and melt. If the system doesn't shut down, then once that first wire melts you're then splitting the 50A over only 5 wires instead of 6 and the others are going to start failing too until the system does shut down...

Same design problem, but it draws less power than the 5090 so is less likely to be an issue.

This was a very very helpful reply.. Thank you so much for real.. So basically what do you think of XPG statement ? like when they say "No matter your XPG PSU includes a 12VHPWR or 12V-2x6 cable, you’re ready to power up and connect directly to the latest RTX 50 GPUs with ease!"

Buddy idk what you want us to say about the statement

It says it has the cables you need to power 50 series GPUs. There isnt anything else to it

like even if it is the 12VHPWR and not the 12v-6x2 still will power up 5090 with no issues huh? sorry for being worried much, but you shoulda said what ppl on reddit been saying .. " if its not an atx3.1 12v-6x2, your 5090 will get melted" so ofc got worried sorry lol

There isn't any difference between a 12VHPWR and 12V-2x6 cable. The power cable is the same. A 12V-2x6 cable is a 12VHPWR cable and vice versa.

There is no difference between a 12VHPWR and a 12V-2x6 cable. The changes in revising the 12VHPWR connector and renaming it to 12V-2x6 were only made to the connectors on the graphics card side.

If the connector melts it'll melt regardless of what connector it is cause Nvidia designed a stupid connector thats bad, doesnt matter the kind of it or if the PSU is atx 3.0 or atx 3.1

Think of it like a car crash, doesnt matter if you are in a ford fiesta from '06 or a ferrari from '25. if you get in a car crash that's deadly you'll.. well deadly describes it

Got you.. So I just plug this atx3.0 12VHPWR in all the way and don't worry about my 5090 getting melted, right?

OMG now it makes more sense like honestly thank you so much.. I do understand now and the pic is clear. Wel,, imma pair this atx3.0 12vhpwr right now and plug it in all the way in and lets hope it won't get melted lol

XPG did reply back to me saying : " it is ATX3.0 ver" so basically some how I got the atx3.0 ver 12vhpwr eventhough I did buy it a month ago and the warranty till 2034-11-30 which means this unit had been produced last December so it supposed to be a new unit yet it's an atx3.0 12vhpwr omg.
