EVGA called out

So his conclusion is that the 500W bios doesn't work (or makes no difference from the 450W one) because the PCIe connection on the 3090 FTW card has a 75-80W limit that can't be fixed without a shunt mod, correct? Maybe I missed it because the guy talks too much, but what limit do all the other cards have on the PCIe slot? Do they have any limit? He does a shunt mod that ups it to 120W (I think that's what he said) but repeatedly said to do it at your own risk.. so by extension, do all other cards have an inherent risk now by not having a 75-80W limit there? Or is that an artificially imposed limit by EVGA, in which case I again wonder what the other cards do there... sorry if he answered this and I missed it, it was late, I was tired, and again.. dude talks too much lol.

I wouldnt trust anyone regarding this pcie shunting, I will do testing with friend who is skilled in pcb designs etc and report back, PLEASE DONT SHUNT PCIE, it may damage your card/mobo.

Unfortunately his channel is extremely tiny, an insect in the grand scheme. But hopefully it helps get the ball rolling.
Even my stock BIOS was messed up, drawing 80+ watts from the PCI-E slot.

There's quite possibly a reason for that.  He's hard to stomach and listen to.  As a middle aged guy, maybe I'm a bit too old school, but the vocabulary he uses is very unnecessary and not needed to be able to get a point across.  I labeled him correctly here in a previous post and hurt someone's feelings here for doing so, but what I said was accurate.
 
Maybe this guy has a beef in general for EVGA, maybe they did not send him a sample to review like they did to some other reviewing outlets and it upset him...who knows.

PCI-E devices on a x16 interface shouldn’t be exceeding 75w. 75w is the power limit for a PCI-E slot. Just like 6 pins are 75w and 8 pins are 150w. You can draw more power from them if the card calls for more power, the power supply will oblige until something breaks, or there’s a hard cut from software or some other limiting factor. There’s a 10 amp fuse on the PCI-E slots shunt (this is the only way I know to explain it) and there’s a 20 amp fuse for each 8 pin. I’ve read that as long as you don’t exceed 120 watts for the PCIE and 240 watts for the 8 pins, you shouldn’t blow a fuse. Someone here has mentioned that a card did blow a 10A fuse, I think that’s the case, where someone had an 8 mOhm shunt mod on all the shunts. Obviously 8 mOhm is too much and exceeded the120w limit.
Other manufacturers have lower power limits set for the PCIE slot. I don’t know the numbers off hand, but I remember seeing the FE was 66 watts and some others are 50w. With three 8 pins, there’s no need to draw 75+ watts from the PCIE slot, Even at 500w.
What I have observed is the card cutting power because it’s drawing too much power from the PCIE slot even when the 8 pins aren’t maxed out. It’s really bad design.
