They are trying to do 480W through USB-B.
CNX Software found out what the cable actually looks like:

GPMI also implements an alternative to HDCP with ADCP content protection protocol based on SM3 and SM4 “national security algorithms” and much faster than HDMI (200ms vs 2s).
It will be interesting to see if this connector gains any adoption in the West.

That doesn't look safe. What amperage is that targeting? In the US, a removable power cord for home use isn't supposed to go over 10 amps nominal, but manufacturers go over that and put "keep unplugged when not in use" in the manual somewhere. That's a pretty big and robust connector, not something that looks like it could just snap in half.

Yeah, if that's right the design is really pushing it.

It's probably 48V, 10A for big boy, because USB PD already uses 48V, 5A to get to 240W.

Why are we even bothering with plastic plugs for consumer GPU power. You're not hot-swapping the GPU or unplugging it from the power supply when you're done for the night so what's the point. Give it two screw terminals and thick solid copper wires so the aesthetic idiots can route them next to their hard loop and we're done. It might also give some courage to work on their houses' electrical shit and kill themselves when they try overclocking the oven to bake pizza rolls better.

And the guys that run $50,000 GPUs in clusters in a fuck-off server can afford a non-melting connector

There is already a standard which will handle the current levels required.

1250V, 3000A. Should even be able to run a 6090 if you undervolt it.
 
Hey boys, I picked up a ryzen 9 9950x, 64gb ram, a ton of storage (nvme, ssd, and 2 spinning disks), to build out my home server/AI lab.

Bros, I did not know the GPU situation. I thought I did, but I did not. I'm going to set up kube and plex, immich, and I'm going to get deep into a bit of networking, and all that good stuff until I decide which GPU to buy.

I'll probably pull the trigger on a renewed 3090 from Amazon, but I wanted to throw it by some knowledgeable guys first. It's really for learning. I run the gamut at work from app dev to deployment, but it's a) proprietary software (even the custom solutions where I get to be creative are limited to that) and b) not as deep as I would like. So this is all for learning and fun and to eventually get the Coolsixtyniner crew totally off Google.

What do you think? Pull the trigger on a renewed 3090? Go to microcenter every Saturday in the morning and see if get lucky for a 1k over msrp 5090?

Yolo it bruv. Just get it.

It's trade war time. I say pick up the 3090 now.
Whatever you're doing, now is better than later. With the idiocy from all current leaders you have no idea what shit they'll get up to next.

OK I bought the ASUS TUF 3090 and it's coming Wednesday. I took a look at the EVGA 3090 for the same price (I have a EVGA 1080ti that's rock solid), but when I was at microcenter the autistic helping me said to go with ASUS, MSI or Gigabyte so I decided with ASUS based on that.

I know I'm just blogging at this point but my girls eyes glaze over when I'm talking to her about this stuff. I am so stoked bros. I have no idea what I'm gonna build or do outside of degoogling, but I bet I can write some agents to do some nonsense for me.

What do you guys think? ASUS TUF Gaming sounds lame, but I read people have found it reliable and it's cooling is effective.
 
I've never heard anything bad about it. I like my Asus GPU so far. I really don't know if the TUF line is all marketing or actually robust tech, but all that really matters is stability and an increase in performance over what you're used to.

The only negative thing I remember reading about the TUF version of the 3090 was something about ASUS skimping on the thermal pads somehow. Probably irrelevant if you aren't planning to cook it with crypto mining though. The 3090 was a little odd for cooling the VRAM since it was on both sides of the PCB so you had 12GB of it getting some amount of contact with the actual heatsink then the other 12GB on the back side left to radiate what heat it could out of a back plate.

I was not a fan of that particular design and eventually put a full cover water block on the one I had due to autism.

Its an ASUS GPU. Be warned of GPU sag and coil whine.

So I'd guess this is PCIe gen 5 at 8 lanes hotrodded to all be tranmit to get to 192gbps. All that plus 480w through a cable the width of Hank Hill's urethra.

Sure, China, enjoy the fires.

from Baidu AI research:
Voltage for GPMI Power Section‌The ‌GPMI (General Purpose Media Interface)‌ power section supporting up to ‌480W‌ typically operates at ‌48V DC‌, a common voltage for high-power-density systems requiring stable delivery and compatibility with industrial/media equipment‌5. This aligns with designs integrating advanced power management (e.g., MCU-driven clock/reset configurations) to ensure efficiency and thermal safety”

Im looking at buying a surface pro business tablet/laptop for a compact pc/tablety thing on the road. I drive a truck most days but go home weekly, and even though theyre fuck huge expensive, I could really use the ultra compact design with the pc x86 compatability. Now I intend to do some gaming, but I'm mostly expecting to play old/ niche shit/ emulators and it looks like the intel i5 business model might be able to pull that off, plus the integrated ai could be useful for doing research about authors that I'm reading via audio book, before I go to bed at night. I dont really use any normgroid or professional software, seeing as i'm paid to sit on my ass and piss in a jug all week, so it seems a bit spensive, but the snappy tablety thingy combined with pc functionality can save lots of the logistics and time of dealing with a laptop in an enclosed cabin. It also opens the door for me to do less nigga tech shit in my downtime on the road. now is this kind of computer a ridiculous boondoggle for me, and i should stick to a laptop, or is it neato and potentially more enriching to my vanishingly sparse downtime to have such a thing on hand? This is a stupid question.
