i had a 6-7 year old pc i recently replaced due to parts dying and the parts needed to replace were not being
supported anymore i had to rebuild it completely anyways i went with the seasonic GX focus 1000W
and was looking at getting a 4090 sometime soon but seeing as i already got the PSU
do i need to replace it with the ATX 3.0 PSU? or will i just be fine with the one i got now?
also im not looking to plug all 4 pcie cables as i seen people mention that draws the 600W?
i also am one to cap my FPS to 60 frames does that not draw less power aswell?
anyways just a question i had to myself through out the day was wondering someone could answer this for me thanks
