Zotac's RTX 50 series will feature a new "Safety Light" to prevent 16-pin power connector meltdowns.

We could be reading too much into this, but Zotac may use the older 16-pin standard for its RTX 50 series.

Don't buy Zotac GPUs, got it.

Zotac or palit...
The palit here with 3 months making bad noise from fan to change it need to dismantle the graphics.

For the uninitiated, Nvidia was the first and still the only one to use the 16-pin power connector on a mainstream graphics card to supply more power over a single connector instead of multiple smaller ones, up to 600W.

Also for the uninitiated: the 12VHPWR connector was selected by the PCI-SIG, and uses a specifically keyed version of the Molex Micro-Fit connector (just as the existing PCIe power, EPS 12C, and 'ATX' 20-pin and 24-pin connectors are Molex Mini-Fit Jr) which have been in use for several decades and are rated for 10A (at 12V, that's 120W) per pin continuous operation.

Interestingly, their blurb mentions "12VHPWR Enhancements", not 12V-2x6. We could be reading too much into this, but Zotac may use the older 16-pin standard for its RTX 50 series.

The fact we can’t tell feels like such a colossal failure of the whole branding and communication around these connectors.

“12 volt high power” rolls off the tongue in a way that “12-volt two by six” doesn’t, and it had already started to embed itself in the PC community vocab. I guess it was disruptive and would be seen as an admission of fault to issue a revision and declare that everyone needed to switch to the new version by some deadline to remain compliant, so the standards body created a new standard with a new name and allowed them to coexist. They’re physically and electrically intercompatible and not outwardly indistinguishable (without markings), so companies keep using the old one where they see it as low risk and are disincentivized to disambiguate, because it just confuses non-technical shoppers and makes them look bad.

Now we can’t tell if “12VHPWR” means the actual old connector, or marketing just trying to not get into the weeds/admit fault.

LED looks like a really good solution to me.

I purchased the Seasonic 12V-2x6 cable last month just in case vendors shipping old cables.

On the video card side they're somewhat limited as to what they can do regarding the connector so this makes sense. Recessed power connectors would inherently help or installing them at the end of the card. Cable wise MSI's solution of brightly colored connector was a good move as well.

While the 12V-2x6 changes are good I still think the entire problem never would have happened if the retention mechanism gave better tactile feedback and was more secure.

Customer service in the GPU sector is dead. So pick your poison.

Lets face it... Since the fall of EVGA, none of the current vendor GPU choices are great... name one like ASUS or Gigabyte and you will find poor customer support for these products. And the only one to blame here is NVIDIA who leaves no room on the table for their board partners to make any profit, so they must do all they can to prevent RMAs from being redeemed. NVIDIA Shares are through the roof because of their monopolistic behavior and I can't wait till the Federal Gov brings them down a notch.

There is no difference between between the 12VHPWR and 12V-2X6 specifcations in terms cables/plugs. The changes were limited to the header (the receptacle on the video card, and on the power supply if you have a modular PSU).

So do you recommend those who have atx 3.0 psu to upgrade to 3.1 psus?

If you have a good quality ATX 3.0 PSU that's working fine, I see no reason to replace it. Just make sure the 12VHPWR connectors is fully inserted and latched (on both ends, if your PSU is modular).

I have the Vertex Seasonic 1000 watts atx 3.0 psu and am using TPU'S gpuz 12v sensor to check for variance since my 4090 launched and app update. Nice Thank you.
