News Seasonic unveils 600W 12V-2X6 GPU power cable upgrade — company's earlier ATX 3.0 PSUs came with older 12VHPWR cables

[Admin]

Seasonic announced a new 12V-2X6 cable that can be bought as an upgrade for its outgoing ATX 3.0 PSUs. The cable is designed to replace its older 12VHPWR cables that were susceptible to meltdowns.

This cable makes no sense. The cable's connectors are the same whether you have the 12V-2x6 or 12VHPWR connector. The part of the connector on the gpu, not the cable's ends, are what's different with the 12V-2x6 connector as compared to the 12VHPWR connector.

The early cables had longer sense pins and shorter power pins. By making the sense pins shorter and the power pins longer in 12V-2X6, it's easier to detect if the cable isn't fully inserted — and less likely to have a situation where you get arcing and a meltdown.

So yes, this cable does make sense, as it incorporates the necessary changes on the connector that plugs into the graphics card.

I say we skip the whole thing and use AMD or Intel GPUs (or ≤75W cards like the RTX 3050 6GB) until a sane connector arrives in another 5 years.

Does this cable solve the issue with not having enough space between the card and side of the case so you have a crazy bend in it? No? Then nothing is solved.

The shorter sense pins and longer power pins are on the connector on the gpu, not the power supply cable end.

True. I guess the question is whether or not there were any potential problems with the original cables that Seasonic shipped. If this is just a marketing stunt, that's a problem, but hopefully it's more than that. Maybe they improved the materials used on the connectors. I guess the only way to know for sure would be to get the new cables and the original cables and then do something like what Igor is doing with AIO coolers. LOL

That does point out something interesting.

Every time there was melting, it was always the GPU melting. Did we ever see melting on the PSU side of the cable?

I mean, the manufacturers always blamed the users.(at least for a significant amount of the time at the beginning) How come the users got it right 100% of the time on the PSU side? Are we to assume that 100% of cable melts always happened on non-modular PSUs?

That all seems a little convenient right?

Great! Now the consumer who already paid for your product can fork out more money to fix YOUR mistake. How about you replace the original cable for free if it's a problem or replace the gpu? Otherwise, consumers should file a massive class action suit against the psu and gpu industry as a whole.

you skip it alone 😛 I will be enjoying my RTX 4090 in the meanwhile.

I'll skip this and the next generation by economic reasons, thanks.
PS5 Pro supposed to have the 7700XT graphical level, is the only sensible choice to have future proof gaming for the next 5 years. also FSR, RT and whatnot, I'll wait for a price drop.

I saw a little while ago that the old cable was available on newegg, but you had to order it from their partner in china and have it shipped from there.

Actually, a be quiet 90 degree cable is more readily available but some of their psu included cables are a little shorter than most others.

Does nvidia disfavor 90 degree cables?

Sounds boring...

Great, looks like this cable won't fit my Seasonic Prime TX-850 or hardly used Prime TX-1000 !!. No idea if they are ATX2 or 3 as nothing is stated on the box.

The ATX 3.0 Seasonic PSUs are newer models and clearly labeled as such on the box if i recall correctly.

As are the latest games.
