TLRD; Is ATX3.1, PCIe5.1, has a 12V 2x6 pin cable.
Okay so I'm guessing that a lot of people did what I did. I read the online description that says ATX3.1 and PCIe 5.1 with a 12V 2x6 cable. Then when you get the thing it says 3.0, 5.0 and the older (yet the same) 12VHPWR cable on the box and you thought you get ripped off. Well I started a return, thinking maybe I got older supply, and ordered the same one from Best Buy thinking well they will give me the right one. Nope exact same box and everything. So I got online; did alot of reading and contacted Corsair and this is what I found out. After cable melting issues started cropping up the older 12VHPWR cable was slightly redesigned with shorter sense pins and longer conductor terminals, but the same cable. The way to tell is to look for the H+(older) or H++(Newer) on the side of the connector that goes into the GPU . The PSU has been rated at ATX 3.1 and PCIe5.1 prior to the new standards but the packaging was never updated to reflect that. It's all confusing and made more so by the packaging. So this cable is H++ Corsair explained the standards not being updated on the packaging. So I cancelled the return and my 5090 is running great.TLRD; ATX3.1, PCIe5.1, has a 12V 2x6 pin cable.

Not for MSI Ventus GeForce RTX 5070 Ti
This PSU won't generate enough power for my MSI Ventus GeForce RTX 5070 Ti. Very strange.

CORSAIR RM1200e (2023) with 12V-2x6 Cable
Muy buena PSU, a pesar de ser ATX 3.0, te trae el adaptador para los nuevos conectores de 12V adoptados por algunas gráficas actuales. En las fotos podrás ver que ciertos conectores les faltan pines, esto me asustó al proincipio, llegué a pensar que estaban dañados pero escribí directamente a Corsair, los cuales me dijeron que era completamente normal, que han hecho ciertas revisiones, prescindiendo de los mismos. Al terminar mi armado de PC, todo funcionó de forma adecuada, sin problemas hasta el día de hoy.

Power Supply.
Great modular cable with plenty of power. Fits in the case easily and has an included 12 pin graphics card cable which was great for my card. Plenty of left over cables.

ATX 3.0 la versión de 2023 aun asi funciona perfecto
La verdad estaba muy desconfiado por este modelo por el relajo que traen con la certificación 3.0 y 3.1 sobre todo en el contexto denuna rtx 5090 y sus conectores fundidos. Este Fuente que me llegó NO es 3.1 es ATX 30 con el conector PWR y las salidas de la fuente PCiE y aun así funciona sin ningún problema. Funcionando con una RTX 5090 sin ruidos raros, muy silenciosa y con el conector que traía en la caja. NO usé el conector de nvidia (el pulpo). Compren con confianza puro marketing el tema del ATX 3.1.
