Finally got my 500watts with my 2 month old Evga 3090 ftw3 Ultra!!
Xoc bios that claims 500watts never did more then 460 watts for me. Early powerlimit after 424watts downclocking the card.
Grew a pair and took baby steps and tried the Kingpin 3090 520watt bios..
Now I get more then 500watts haha.. 516watts max so far just playing around. So awesome thet a bios can fix it as I was thinking I needed to hard mod the card to fix the issue.
Now so far my power lines look like this:
Pcie = 70 watts
Pin 1 = 170 watts
Pin 2 = 166 watts
Pin 3 = 107 watts
Don't know if I'll be brave enough to try the kp 1000watt bios. Atleast I finally got what I payed for.
EDIT: Short lived i guess... Card locks up alot durring 3dmark benches. Just seems off.. no idea if i need to reinstall the drivers with the new different card bios or what. Most likely going back to the original bios tomorrow.
