Hah, that's an interesting find alright; few power supplies have native 12+4 pin ATX 12VHPWR connectors; early adopters of the GeForce RTX 4090 graphics card will require an adapter cable to convert ... ZOTAC Mentions that ATX 12VHPWR Adapter can Connect-Disconnect 30x only
Yeah Steve mentioned Nvidia did extensive testing of 8 pin to 12 pin adaptors an major fail points was 40 connect/disconnects and excessive bending of the cables, caused the cable to catch fire an burn peaking at 200c + on thermal camera at the failed point.
It is definitely something very serious and would have to be considered. I personally will be far from these adapters in case I buy a GPU with the new 16 pin connector, I would better buy a new ATX 3.0 power supply
These adapters are intrinsically illegal. If you use one of them and you have a house fire... all insurance companies will laugh before your face
its not like the 8 pin microfits have much better. "without context that's not necessarily a useful piece of information. Mini-fit plus connectors (similar to PCIe power) only are rated to 75 cycles on an entry-level connector."
If the pin layout is on top of the gfx card like most are then there's no way you could bend that 4-1 cable tight enough to hide the 4 x 8 pins around the back of the case. This is why i would need a new PSU cause i really don't like the look of that 4-1 cable. 30 cycles should be plenty, in 18 months i've only pulled the gfx card out once and that was a few weeks ago to check if it needed cleaning but only the back plate was dusty. There's no way you could bend that cable near the 1 plug so that means you'd have to bend near the middle and the 4x8 will be seen inside the case.
O_O ok I guess I'll wait one of those new psus with 1200+watts not like I was going to buy a 4090 I wait 7950x more than that as single thread limited games are still a thing
Will until someone gets a house fire before 30 disconnects and the lawsuits start coming in. Bet they'll put a little more thought/money into the adapter design.
If the adapter is so hazardous, it's quite clear it hasn't gone through any inspections, probably not even on the computer screen before manufacturing. Some fake engineer just put it together and everybody said: "This is fine."
lol no. the value is how many insertions before metal fatigue introduces measurable contact issues, and only relevant to forceful application.
Good luck finding one, they're not exactly easy to come by. nVidia could hardly base their sales projections on 4000-series adopters also buying new ATX 3.0 PSUs.
Hard pass for any GPUs that have that connector. its like outfitting a bugatti car with tricycle wheels. (But still charge you the full bugatti car price and more).
