I hope your prebuilt PC comes bundled with a fire extinguisher.

Just inspected my cables and 100% fine so far and I have stressed the shit out of it
Now wonky drivers and getting some odd performance here and there is a different story

Did you get an atx 3.1 PSU with the "new" cable?

What has always bothered me the most about the controversial 12VHPWR connector is the people who defended it and blamed other users for "not knowing how to connect a cable". Fanboyism sucks, and I say that as an Nvidia user for several generations.

AMD please don't fumble the 9070 XT. AMD save us AMD please

Ok it says ATX 3.1 on the Thermaltake PSU Toughpower SFX 1000W so maybe I am ok
Now I'm thinking it'll be a good thing if it sells out and I can't get one for a few months. I can find out if there's any "surprises" with it. (The people that do get it will be the beta testers.)

Damn, this shit is stressful.
I have a Asus Tuf Gaming 1200w Gold PSU, and I feel like a detective checking what kind of ATX this thing actually has..
And does it even matter??
The info from the store where I brought it writes that is's ATX 3.0, and there's no info about it being ATX 3.1 anywhere, except on the Asus page.. which should make me feel safe, but why is the 3.0 info everywhere else??
Damn, this shit makes me paranoid

My 4090 while OC'd pulls 570 watts alone (that's what HWINFO64 shows). I have an MSI ATX 3, 1300 watts psu. 12VHPWR cable directly from psu to GPU. Never had an issue. But the thought of this thing pulling more current is worrying as hell. I don't think i will be able to game without looking at my gpu every 5 minutes.

Maybe it will just have 3 8pin connectors. I have not seen any rumors yet.

Oh no you're not. Did you know the latest driver update was just pulled, because some GPUs were bricked?
Nah, NVidia has been quiet about the driver issue, other than acknowledging it, just messing with you.

didn't the 4070 also use 12VHPWR? I thought every 4000 series card used that
either way, it's just not good looking. I want to upgrade to Nvidia but i'm not ready to spend twice what I wanted to pay just for a backup GPU

Ok you should have the pins that protect against improper connection. 12v-2x6 versus 12VHPWR, it's minor but might keep us safe as long as the cables don't melt lol.

My 4070 has 2 8pin connectors. It also dosn't require much power though.

No problem with 5080 and lower tier cards. For 4090 and 5090 this power connector is operating too close to theoretical limits.
4090 and 5090 should use two power connectors...

What a time to be alive. Nintendo users are hoping for 30fps most of the time at sub native res while PC enthusiasts have to get a proper house insurance for their GPU. Funny thing is, there's plenty of overlap between the two groups.

It's because the differences between 3.0 and 3.1 are very minor that many 3.0 already meet or exceed 3.1 so the manufacturers have jumbled it all up.Does anyone understand if this info means that the PSU is atx 3.0 or 3.1?
Sorry for (probably) dumb question..
A "real" 3.1 will say 12V-2x6 instead of 12VHPWR for the connector but that's just a matter of pin length at the connector and that cable would work in either plug.

Guess i'm still gonna hold on to my 3090 for the foreseeable future...

Guess I'll keep my 5090 undervolted with higher efficiency for the moment.

When we pulled our old HVAC and installed different zone heat pumps in the house I am pretty sure I recall them saying these heat pumps would run on that
Almost 23 amps going through that shitty cable. (edited, not enough for an AC)
Maybe I am way off

I don't have any Nvidia stuff at the moment (except a 1650 in a laptop) but it was pretty obvious that a lot of it was user error. There are a lot of 'enthusiasts' out there that have minimal skills but over inflated egos.

No need. It has 300w wattage.

It's going to take some politician's house getting burned down by a 5090 for there to be any chance of Nvidia being taught a lesson. Oh and it has to be a republican's house because democrat's would just lulling people to sleep with kind words like "this is outrages!" instead of saying "Nvidia cooked my children!!".

Seems like the XX90 series will forever have a curse. Can't wait to see what the 6090 does to people's PCs.

Hm, seems to be a Founders Edition issue.
No reports of this happening with partner cards?
Maybe they should have kept the big form factor with a bunch of extra cooling..
