Does Steve sleep? GN is a team sure but they aren't LTT sized at all yet I see Steve doing indepth content after indepth content with massive investigations inbetween
imaginary_num6er@reddit
He’s consuming thermal paste for subsistence, but seriously he should get sleep
halotechnology@reddit
Can I get some of that thermal paste ?
piexil@reddit
I don't really watch him but I remember him a few years ago saying his personal system was actually really outdated specs wise and he doesn't keep up with it personally because he never uses it. he basically only does work all day
P_H_0_B_0_S@reddit
If last year is anything to go by, LTT do large amounts of recording there, then drip the content out over the following weeks and days rather than do as much editing on site. Think it was part of the corp reset sparked by GN investigation to reduce crunch. Ironic.

Bad case of workaholism.

It's concerning, and I've mentioned it in comments on their vids quite a bit (as I know the team reads comments to a point).
Hopefully he and the team take a bit of a break after. You gotta look after yourself - a lot of times you don't know something is wrong...until it goes wrong!
theholylancer@reddit
I sincerely hope its freelance editors helping out during surge week, with say notes done by the normal folks but the actual grunt work done by a whole bunch of hired on temp editors for just this reason...
APGaming_reddit@reddit
It doesn't fix anything it just tracks voltage, temps, and power
P_H_0_B_0_S@reddit
TBF the title of the video is a bit misleading, even though a product I have been begging for and will be getting when released.
That * in the title is doing a lot. More issues mitigated than fixed. The ability of the it to shut down your computer in case of a issues is mega as even Astral cards cannot do that.
Starbuckz42@reddit
No one but nvidia can fix it.
What this does is enable you to safe your card from having to being repaired.
That's all we can expect at this point, there is no solution, only measures to minimise the damage.
Raizer88@reddit
Overengineered a bit? I think a fuse box would be more useful and cheaper to implement. If a connection fails and the remaining cables start drawing more current, the fuse would blow, protecting the connector.

Not a bad idea. Now you just need to build it, and sell it.

Let's try to convince the industry to use 24V instead of 12V for better efficiency and keeping the cables thickness reasonable.
f0000@reddit
If we’re changing voltage anyway, why not move to 48v. It’s the highest dc voltage in widespread use, and we could power stuff via PoE more easily :)
Strazdas1@reddit
because stepping down from 48V to 1V inside GPU would be challenging to say the least.
slither378962@reddit
48v exists in servers. Smart people have already solved this problem. There may be some downside like it's slightly less efficient or something like that.
_zenith@reddit
Nah you can get tiny chips that do larger step downs than that these days. They’re amazing tbh
dfgsdja@reddit
What tiny chip can do 48V to 1V?
mrheosuper@reddit
What would be the challenge ?
ElementII5@reddit
Modern chips "consume" electricity in the 1-2V range. The bigger the step down the more complex the circuitry to make that step down.
12V --> 2V is a lot easier to handle than 48V --> 2V.
Yebi@reddit
I don't know much about it to be honest, but looking at the price and size of 240 → 5 charging bricks, it really doesn't look like it would be a problem
spazturtle@reddit
And what amp are those adapters? On a GPU you are looking at 600A.
basil_elton@reddit
They don't step down directly from 48 V to 1 V.
wakIII@reddit
Yeah, all our busbars are 48v and we have native converters where applicable. This stuff exists in pretty wide use and gets cheaper the more it gets integrated. We used to use it for some of our proprietary expansion cards, but re-purposing pcie edge connectors with 48v lines instead of data lines is a recipe for disaster when someone doesn’t understand the board layout and plugs stuff in the wrong slot 😂
RandomPhaseNoise@reddit
Use the already available 12 v ol the PCI express for up to 75watts. And more juice should come from the 48v aux power cables.
And forget that small shitty connector! Use something safe!
Mobo can also get main power of 48 volt and can convert it to the required voltages locally.
And please keep all connectors the same. No need to have separate types of connectors for CPU aux and GPU aux! Who was that drunken ass who thought having different pinout for the GPU and CPU is a good idea?
Standby voltage, PSU control, power good signal could come from a smaller connector.
And I would recommend obligatory PSU fan tacho and a PWM signal which tells PSU load.
Extra:standardized some kind of diag with i2c or even with usb. On the same small connector. So no more clutter!
cheekynakedoompaloom@reddit
you default to 12v until the device negotiates 48v with the psu just like phones do with usb-pd. everything stays safe and depending how its done you retain some to significant backwards compatibility with dumb psus and gpus.
CazOnReddit@reddit
NVIDIA: Best I can do is continuing to but just do things like the 3090 Ti's 12V connector
TenshiBR@reddit
Nvidia: well, we fired the 3090's engineer. The temp we hired in his place says the new connector is super safe. It was the reason we hired him immediately at the interview! He also signed a contract where he takes full responsibility in case anyone dies due to fires. Win Win. Now, let me finish this yacht purchase here. It comes with 2 free leather jackets.
P_H_0_B_0_S@reddit
Nice of Nvidia / PCI-SIG to create business opportunities for others in mitigating their design issues... Thermalgrizzly and Seasonic thank you for this.
Mad that PSU and prove maker is putting in stuff that should really be in the GPU.
One sale here as a lot cheaper than the extra for an Astral card, plus has the extra of a physical cut off functionality.
Visible-Chapter-1871@reddit
When is he going to start selling this though?
Icy-Communication823@reddit
The Nvidia humiliation is reaching absolutely brutal levbels - and I fucking love it.
