Will a 750 watt psu cut it?

[sambriggs]

I have a mini itx form factor pc. I currently have a Ryzen 9 3900x, rtx 3070ti, rog strix b550-i, ek aio water cooler, 32gb of ram, one m.2, one 2.5 SSD, one 3.5-inch junk drive, 5 cooling fans, and all ran off a 750 watt psu just fine. I just purchased a 3090ti and I would like to cram it in this tiny pc. I would like to know ahead of time if I’m going to have issues of not having enough power. I’m hoping the 750 will cut it but I’m here for a second opinion . so let me know if you think it’ll work or if I need to move to a 850 to prevent damage. thanks.

what is the make and model of that power supply?

750w is not the same across all brands, especially the cheaper ones.

they state a 850w is recommended.

that answers the question for me - always go with the recommendation and then add a bit.
