Yeah, what would help safeguard against failures is actual (calibrated) thermal probe next to the connector connected to warning LED or buzzer.All these nice little changes fail to address the main issue, it's still a flawed design with too little room for error. I would not be surprised if we see yet another change to the "standard" once the 500W+ GPUs reach the wild.
The good news is everyone with < 400W GPUs is safe using it by now. That's where the rating should have stopped imho, any 400W+ card should carry two connectors.
I don't know about the earlier PCIe 8pin's 80% figure or the 90% claim for 12VHPWR, but surely 600W / 756W is about 80% which is far closer to 90% than 50%.
To this day, I can't see any possible advantage to these new connectors yet Nvidia stubbornly stick to them in some Apple-like "we know best" attitude.
ASrock uses this connector too for the 9070. Nvidia is using the 12V-2x6 port, none of the 50 series will be using 12VHPWRTo this day, I can't see any possible advantage to these new connectors yet Nvidia stubbornly stick to them in some Apple-like "we know best" attitude.
Again, this is simply you being ignorant of that connector ratings mean. Spikes are a complete non issue. The card would need a spike bigger than it would take to melt it's silicon, to harm the connector.
These are standard Microfit 3 connectors, rated for 10.5 Amps x 6 pairs x 12v = 756Watts in 12 pin config.
Plus, again that how much it could handle continuously over long periods
, and that will have it's own safety margin built in
, so it could probably handle more beyond that indefinitely.
Too bad that the "1 will do" part did not turn quite true in practice.The advantage is blatantly obvious. 1 connector and 1 wire set, instead of 4 of each.
I certainly wouldn't want to deal with 4 power cables sets and connectors when 1 will do.
AFAIK they're going with 1 on the 5090, we'll see how it holds up.Too bad that the "1 will do" part did not turn quite true in practice.

That's unfortunate. It shows they haven't learned their lesson.AFAIK they're going with 1 on the 5090, we'll see how it holds up.
No half plugged in connector is safe. Now that the Sense pins will stop that, one will be fine.
No need for "half plugged". 1 mm off is enough to be a potential danger.
Also the sensitivity to any bend in the wires near the connector.
They should increase the PCIe slot's power delivery to 150W minimum or introduce an additional dedicated power connector right next to the PCIe slot to provide power. It's stupid to have a huge cable going to the GPU when power could be routed through a cable connected to the back of the mobo's PCB or next to the ATX connector where the cable wouldn't interfere with much of anything else.The newer 12V-2x6 fudges capacity a bit by mandating that cards that use it allow up to 75W through the PCIe connector on the motherboard, effectively increasing its rating and capacity by 75W.

The discussion is about delivering 150W through the standard PCI-E slot.
It will take some load off of the existing cable at least.Not sure what that would even benefit. When the concern is high GPU power usage, adding 75W to the slot seems to be deck chair rearrangement.
The extra head-room would indeed be just a band-aid for the bigger problem: power budgets in the modern PC are out of control, doubly so on the GPU side.Not sure what that would even benefit. When the concern is high GPU power usage, adding 75W to the slot seems to be deck chair rearrangement.
The amount of people who have a motherboard with that proprietary connector on it, a GPU that uses it, and a GPU that draws large amounts of power is probably too small to draw any conclusions on its safety tbh!Haven't read about any fire issues with mobos like these: https://www.asus.com/me-en/motherboards-components/motherboards/tuf-gaming/tuf-gaming-z790-btf-wifi/

You are neglecting cable size i.e AWG.Actually there is lot of wiggle room for that. Cable/Connector Power ratings are based on long term heating thresholds. It's not about sudden failure based on exceeding a certain value.
It's spec'd to deliver 600 watts endlessly and not heat up too much. A short term spike is not a problem. It's the average over time that cause too much heat.
You could pump 800W through it for minutes in a row, if you let it cool a bit after before resuming load. But if you could make it draw 800W for hours, then you probably would end up causing problems, but you aren't doing that with out power shunt mods, and if something goes wrong you only have yourself to blame.
SE above, 4 cables at a lower gauge will dissipate heat from high amperage than 1 ONE lower gauge wire. PERIOD.The advantage is blatantly obvious. 1 connector and 1 wire set, instead of 4 of each.
I certainly wouldn't want to deal with 4 power cables sets and connectors when 1 will do.
NOPE let be generous and say they they were 16 AWG, it will not be fine. remember normal PSU wires are 18 AWG.No half plugged in connector is safe. Now that the Sense pins will stop that, one will be fine.
You are completely forgetting the OHMS law, in order to supply additional amperage, you MUST increase the wire gauge. IDK if 14 would do it, maybe 12. It is for those companies to figure out. RIGHT?Not really. The sense pins have been shortened, the power pins lengthened. The sense pins now lose contact long before there is an issue with the power pins.
You have to properly seat the cable, or the card wont' run.
You are drastically over-estimate cabling requirements. Do you have small plug in space heater. Go check the cable that plugs into the wall. It's probable several feet long, and I bet it's not larger than 16 gauge (We have three here from different brands and none are). That's something that meant to be left plugged in at full blast (they are pretty much all 1500w/12 amps) indefinitely.You are neglecting cable size i.e AWG.

Space heater and hair dryers are meant to dissipate the heat at their coils. False comparison.You are drastically over-estimate cabling requirements. Do you have small plug in space heater.

That's 12 amps, 24/7 through a power cord longer than anything inside a PC.
For shorter term appliances like hair driers (often rated 1875W 125V@15Amps), they are allowed to pull right up to the standard 15 amps of wall sockets (backed by 15amp breakers) over the same power cords.
As for these GPU connectors:
At 600W/6 pairs, that equals 100W/pair, and 100W/12V = 8.3 Amps.
You think that wire that is used extensively, to supply 12 amps continuously 24/7 at longer lengths for space heaters, is somehow insufficient to supply 8.3 amps in shorter lengths, for a more intermittent load in a PC??
Current capacity of cabling, was figured out before you were born. They aren't under-specifying the cabling.
