MSI GeForce RTX 5090 Lightning Z Is Already Brewing Up a Storm Thanks to Its Two 12V-2×6 Connectors and 2,500 Watt XOC BIOS

MSI has a key note scheduled for 2pm ET/11am PT at their CES room today... Might be related?
 
Yep, this and a bunch of monitor-related stuff, the amount of different things I saw on the weekend got confusing after a bit.
 
Man talk about a halo product. You need two dedicated power supplies to feed that beast of a card and potentially a 3rd for the rest of the system. And maybe even commercial power to feed those! Yeesh... Im pretty confidant my home power wouldn't cut it without some creative solutions. Dividing my office power between two or three breakers for one.... maybe a power bank for one side of the power... or a generator.
 
Well, there is the PCIe but I know that still doesn't make up the different. Could be that the special BIOS allowed them to pull more, just like how that ASUS ROG BIOS does for their special 5090, I think that one allows something like 800 or 900 over the one connector.

J2c has been pulling 1k+ over a 12vhp.
 
I remember back in the good ole days. Silicon lottery was a thing. Getting the best CPU that can overclock.

Now it's a connector lottery. Getting a connector built within' the right tolerances that doesn't melt.
 
Sad but true.

For my builds I even went so far as to put a case fan nearby the GPU connector to help keep its temps down. Truly ridiculous.
 
It aint heat that kills those connectors.
I can't wait to see what MSI charges for this card......$6K??

I mean technically it is, but a case fan isn't going to change much either way.

If you could cryo-cool the connectors then it would be fine. It would lower the resistance to a point where it wouldn't melt anymore.

but again, a case fan isn't getting those kind of temps haha

but it's a BTF card that should also use the back connector, he bypassed it since he does not have such a mobo on hand also it drew around 760 watt iirc.

Look at the asus xoc card he did with ln2 oc.
 
At this rate though, I'm pretty doubtful that NV is going to launch anything next round which will hook me again. They'd better get a handle on the power consumption and connector before I buy another flagship card. I'm undervolting both of mine and they're doing great but I've also tested OCing them and the FPS gains were just not worth the risks, noise, temps, or power draw. I've said it many times, the 5090 GPU is a beast when undervolted but when they push insane power through it, it becomes more of a literal hot mess.

All these folks going crazy with upping the powah need to provide more than just the 3Mark, etc, benchmarks show some gaming results because I am at least more curios for those even if I don't think it's worth it. Meanwhile if NV is going to start making 1000W+ cards to achieve the same results, all the more reason I'm done with them and will be looking at other alternatives for my gaming needs.

this forum is full of addicts - my money is on most of you self-exercising a kidney while laying in a bathtub of ice to get your hands on one before the subsequent Ti respins hit the market
