The hybrid can handle 450-500w with good fans on the rad. Won't be quiet if you want to keep temps relatively low though. Remember that the same hybrid kit is used on 3080ti and 3090 FTW3's.

im actually concerned about the other bios and fan controls

Yea that can be problematic. Might have to put the rad fans on a mobo header. VRM fan would probably work good enough, but obviously have to try it. That's the setup I had on my 3080ti FTW3 hybrid when running the Galax 1kw bios.

Some more testing to show the BIOS works as it should up to 430w
 

 
1.05v is at least allowing me to play at 2100mhz (doesn't mean it's fully stable, but it's not crashing within a minute or two). So, at 111% GPU power usage out of 118%, still holds the frequency.
 

 
On this in-game scene with an NPC and a fair bit going on, you see a jump up to 118%, this is the max for this BIOS, so power level hit. Voltage drops and core frequency drops. As expected. Because yeah, Metro Exodus with RTing on at Ultra is just a monster. Can eat 430w for breakfast.
 
It returned to 2100mhz when the scene calmed down.
 
Now, how on earth do I contact EVGA about this? The last conversation I had with EVGA CS when they were going to speak to the BIOS team resulted in me being ignored, never got a follow up. I've quoted Jacob on this forum, and was ignored.
 
This BIOS works to get this card drawing up to 430w, but I'd very much like EVGA to fix their BIOS and make it so we don't need to use an MSI BIOS on our EVGA card. Given the wattage monster that is Metro Exodus, that 20w extra up to 450w would be even better, but I would take a small win with EVGA releasing a 430w BIOS.
 
edit - Power supply power usage has shown a spike to 700w in/652w out whilst playing Metro
 

 
I'm beginning to think this BIOS is allowing the card to draw more than 430w, as I cannot "find" what else would be causing me to see a spike to 700w. Around 600w power in is what I used to see on the EVGA bios. Maybe a little more. Nothing else in my build has changed since I made this topic. Even giving my old pictures in this topic some breathing space past 600w to 610~615w, that's still 80w extra now.
 
I guess I'm questioning whether or not the MSI BIOS sets a 430w limit or if, by chance, it just happens to interact in a way with this EVGA 3080 that it essentially sets no power limit and lets the card draw whatever it can. Safe, in theory, unless there is no balancing protection on any pin and it's a free for all lol. My card isn't getting any hotter than 42~44 degrees playing Metro on this BIOS, but I guess I should open my case side panel and check how hot the pins are.
 
Another reason why EVGA need to look at this and figure out why a 430w MSI BIOS is "unlocking" power draw on this card past 400w.

After reading your posts about the MSI bios I decided to try it on my 3080 12GB FTW3 card. With the normal bios it will draw 450W under heavy load such as furmark but under normal loads only around 420W. With the MSI Suprim X bios I measured the current on each 8 pin supply with a clamp meter while running furmark and found that it was drawing 163W, 225W, and 83W from input 1,2, and 3 and software reported 63W from the PCIe slot for a total of 534W! As a comparison with the normal EVGA bios I read 135W, 188W, 84W from inputs 1,2,3 and 47W from PCIe slot for a total of 454W. The card will also draw more power under normal use with the MSI bios pulling around 480W instead of 420 in benchmarks.

What does GPUZ/HWINFO show for power readings on the EVGA bios?  Curious how the monitoring app readings compare to the clamp meter readings.

Had no idea how it would work on the 12GB card as the 3080 12GB PCB from EVGA is supposed to be better. I take it you were running a Suprim X 12GB BIOS and not a 10GB BIOS? I don't even know if you can technically flash the wrong memory size, so I'm just going to assume you were on a 12GB BIOS.
 
225w off one pin is a bit concerning lol, but it does show how that it is drawing more power.

No, you can't flash a bios with a different device ID. (which is different between the 10GB and 12GB bios).

Thought as much! I do know from accidentally trying to flash a non-LHR 10GB bios to my card it just flat out refused to accept it, even with -6 in NVflash.
 
I guess the concern now is if the MSI BIOS just causes all EVGA cards to draw all the extra power through pin #2 lol. What are pins supposed to be max rated for, like 185w?

Well the spec is 150w, but contrary to some opinions, I've found they can easily handle 200w or more as long as you have good cables.

I don't think anyone would say that they can't handle any amount of watts if designed properly to do so.
The opinion, on the other hand, is that if you don't know what you have or didn't engineer it yourself, you shouldn't exceed 150 watts as a matter of practice. A standard is in place, and you shouldn't assume that whomever made you cables, connectors, crimps, plastic, insulation, etcetera, made it to safely exceed 150 watts by any large margin.
It's a Class 1 electronic product. Almost anything goes. QC and engineering are at the lowest-end. Quality control of a Class 1 product is function. Almost any abnormality or visual defect is allowed as long as it passes the minimum functional checks, and defects which pass a functional check are considered process indicators instead of defects and indicate something which can be improved in the future, but still are considered acceptable. I wouldn't bet my house on it.

I'm using Corsair braided cables with my Corsair HX1000i, so here is hoping the cables are as good as the power supply lol. Especially as I'll guess the behaviour on the 3080 10GB is the same as the 12GB with the MSI BIOS, it's drawing most power off pin #2.
 
It is interesting to me how this can happen, meaning, it's partly a choice by EVGA to limit power on some cards? Or, is the EVGA power balancing mechanism/PCB still crap and all that is happening here is totally brute forcing power draw?
 
I guess what I'm asking is can EVGA actually "fix" their 450w 3080 BIOS or is this luck of circumstance that an MSI BIOS manages to trick an EVGA card/PCB into drawing more power?
