I'm planning to upgrade my GPU to RTX3080 because i want to switch to 4k gaming (living room with LG55CX 120Mhrz monitor).

I heard that there could be incompatibility issues with the RMi 750w model and i have some doubts,

If there is an issue, can i  find a solution for or do I need to replace the PSU?,

 

Thanks!

Did they explain why they thought there would be compatibility issues?

 

I see no reason why the RM750i would have issues with the RTX3080.

At the compatibility notes i receive this message ( i know to take such in moderation )

Note: The Asus TUF GAMING X570-PLUS (WI-FI) ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Corsair RMi 750 W 80+ Gold Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it.

 

I still haven't figured the additional 4 pin connector thingy, I know it's not a big deal but it made me wonder if there are any other stuff (mainly the GPU) i need to take in consideration.

The 4pin connector is for powering the CPU, and is optional. The 8pin EPS12V connector is more than capable of powering the 3700X. If you want the additional CPU power connector you can buy an additional power cable separately (Corsair Type 4 EPS12V), or grab a different power supply that comes with two cables in the box (RM750x, HX750, RM850i, HX750i...)

 

The 4pin CPU power connector won't be a concern for the graphics card.
