Yes but theoretical knowledge is well just theoretical. I see it often when these how do you call it in the us college? they are done with studying get good job but they dont know anything....they think they do but its just horsecrap. if i would do things like they think we would go broke withing a month.
Matters not one bit how new or perfect of a 550w PSU you have. It lacks in two highly important regards; Wattage, and because it doesn't provide enough of it to power 3 PCIe concurrently, the required cables to power your new GPU. Very cut and dry unavoidable facts.
Lets just try it i have everything here by wednesday i guess. Its that simple, if it doent work stock . I can simply undervolt then it will work 100% you know it , i know it the whole forum knows it.
i can buy the psu at any time later it doesnt matter, nothing can go broke. Anyone with a degree of anyzhing should know that about modern components in 2024. we dont have 2001 anymore where you could grill your parts.
i mean you can today too but only with insane bios changes and what not. Stock ? never. If a psu is not enogh it will simply trigger a protection circuit.
you act like this is a 3090 powerlimited to hell card. yet its only 260 watts at average. even a 3090 would work undervolted at least theroetical

.
also the peaks are fare less worse than ampere.
i still dont understand why i should give a crap if a psu is working at best efficiency? its even on the box its not that much worse with 80% unless seasonic lies. which would cost them their ass here in europe.

i will tell you with data when its here okay? til then every discussion is worthless. i think this thinking is simply psu upselling. sure if you have an intel in it, that draws 130 watts while gaming then yes i would certainly agree but a ryzen 5800x3d is 35-80 watts depending on the game. and 100 watts with shaders compiling.
i looked it up 4070 ti can go down to 220 watts and not lose as single % of Performance. With 180-190 watts you lose a few % but here we are and you think this will not work? i would say if you undervolt it that much it will work on 400 watt psu like a regular 4070.
a 550 watt psu can withstand 600 watts spikes easily. at 650 it goes out. if we are talking about a quality psu of course the cheap china psus that halfway explode, if you look at them wrong is another story and are illegal anyways.
Acceptable - given your portrayed knowledge and experience level is basically every single suggestion thus far provided.
i dont have much knowledge but we are talking about hardware for videogames there is not much to learn in my optinion. i would rather learn perfect english. im struggling with grammatics, i think.
sorry for my terrible keyboard writing skill i have mechanical engineering hands.^^
