Upgrading from 3090 to 4090

[Vincentds]

Thanks alot for the information! This will def help!! I will def keep my current PSU.

You have 80 Plus Platinum rated PSU, that guy is just trying to push a €340 PSU on to you to boost his KPI for the month. That PSU is also 80 Plus Platinum, it has the same connections as your PSU:

So no native 12+4 PCI-E only 2 8-pin cables terminating as 12VHPWR on GPU end.

Cable that comes with 4090 Suprim will be perfectly fine for your PSU - it's made per Nvidia spec for Nvidia, which then delivered its to board partners. It's only a matter of visual/aesthetic - if you want a cleaner look contact Seasonic and get yourself a €20 12VHPWR cable for your PSU - you will not need to ugly splitter, not buy a €340 PSU which basically achieves the same thing because it's already bundled with one.

[Why_Me]

Hello all! I build a new pc end of last year and i'm looking to upgrade my 3090 to a 4090. I was in talks with my dealer and he told me I needed a new PSU for the 4090 as it isn't compatible due the card needing other cables. As far as i know you can just plug a 4090 into any premium PSU if you use the correct adapter. I have a feeling they are trying to sell me a new PSU for nothing.

My specs:


I9 - 12900K

Seasonic Prime PX-1000 80plus platinum


H150I Elite LCD


Veng pro 3600 34GB DDR4 RAM


Windows 11 Home 64bit


3090 gaming x trio


MSI MPG Z690 EDGE WIFI


case: TT view 71 TG RGB plus

What do you guys think? Do i really need a new PSU? The one i have is as good as new and was quite costly.
They recommended me the Asus ROG 1000P2 Gaming

Thank you for you time!

Just curious but is your build for gaming or work and if it's for the former, what is your resolution?

It's a pure gaming build! I'm gaming at 1440P (lol) but will upgrade to 4K with 4090. I have a seperate work computer. Why are you asking?

I was going to say the 4080 16GB would be the way to go for 1440 but if you're upgrading to 4K then you're on the right track with the 4090.

No need to upgrade the PSU.
