Question Upgrading my Lenovo Desktop PC with an RTX 407 0TI ?

[Park_Triolo]

I was thinking about upgrading the GPU in my Lenovo Legion T5 26AMR5 desktop PC from an RTX 3070 to an RTX 4070 TI. Has anyone out there tried this with success? I know I would have to upgrade the power supply.

You should be able to drop in the latter GPU, though my question is, how old is your PSU in that prebuilt? To add, you should remove all GPU drivers from your platform(Intel, AMD and Nvidia) before you remove your RTX3070 and reoplacing it with the RTX4070Ti.

Once you drop in the latter gen GPU, manually install the latest driver for the GPU sourced from Nvidia's support site, in an elevated command, i.e, Right click installer>Run as Administrator.

Would also be worthwhile to see if your prebuilt has any BIOS updates pending, prior to the GPU upgrade.

Thanks for the quick reply. Well, the PSU is as old as the system itself, which I bought 2 years ago almost. It's still a beast, though. I did some digging and found out it's 550 W and as far as I know the 4070TI needs 700 W, which I am well aware of.

Well, I only have the RTX3070, so I guess it's more or less easy to remove all GPU drivers, or am I wrong?!

One thing that made me think though, is that my BIOS version seems to be from 2021, but I think I saw one from 2023, although my PC tells me everything, including BIOS is up to date... odd.
