Article is a summary of der8auer’s video. Measurements show 22A/260 watts – nearly half of the card’s power draw – going through a single wire heating it up to 150 °C in an open-air test bench.
It’s just a bad design and a bad standard.
I don’t understand how the ATX standard hasn’t adopted higher voltage rails for GPUs. Higher volts mean fewer amps which means less heat. 44A through an 8 pin connector is going to make a lot of heat. 11A at 48v would be much better.
Apple did something similar, then they put 48V pin next to 3V pin 🤦
That’s…sooooooo Apple…FFS 🤦
Anyone wanna take bets on how long it takes before there’s a lawsuite?
Time for a large busbar connecting the power supply, motherboard, and graphics card?
A 48V rail would make more sense. Just like USB-C did to get 240W power delivery over a small cable.
There wasn’t even anything wrong with the minifit jr 8 pin pcie connectors, the official spec of 150W massively derated. If Nvidia really wanted to cap the number of plugs and not change any specs then the 8 pin EPS connectors are rated at 288W.
If they did that then they likely would end up with melted 8 pin connectors as that derating is a protection against one pin being overused due to small expected differences in resistance on each pin
I’m not saying to ignore the derating, I’m saying use EPS connectors at their derated 288W.
Using custom cables even in that scenario would still lead to cables melting.
It’s from increasing the cable length and therefore the required power draw to draw the required amount to power the device. It already happens with 8pin systems as well, this isn’t unique to the delivery system either.
Using too many extension cords has the exact same affect… it’s like blaming the heater because the cords melted. But no, let’s not blame physics, let’s blame the GPU(heater) -.-
Now you’re really showing how uniformed you are. It’s not an extension cable, it’s 20cm in length total which is significantly shorter than what comes with standard 12Vhpwr native PSUs at 60-70cm.
Did you watch the video?
Sure they did…had their eyes crossed, fingers in ears yelling:
AHHHHHHLALALALALALALALAALLALALAAALLALALALAIIIIIIIIIIMNOTLIIIIIIISTENINNNNNG!
Case is ground, and one big +12V pipe through the middle. Or, alternatively, the other way around for theft protection.
This comment section looks exactly like the one he called out in the video.
It’s mostly just one loud person who very apparently has not actually interacted with the case presented here. Either through ignorance or to purposely deflect the blame from Nvidia with the evidence weighing against them.
I thought blocking .ml would end the troll-madness, but - apparently I didn’t. Well, at least the rest of the comments here show me that I’m not crazy or smth :3
Alts are a thing. Seen a bunch of folk with very similar handles and writing from .ml/world/SDF and some smaller instances.
