3090 Power Requirement Question

Hi everyone,

 

I am not considering buying this, but when I looked through the specs I was surprised it came with a 750w power supply.

 

From my frankly limited knowledge I would say that not enough. Am I right or wrong?

It is paired up with a 45W mobile CPU, I would say its fine.

750W is fine, as long as it's a decent PSU. And I'm sure they tested the configuration to make sure it works, before selling it. It is true that even some 850W PSUs have issues with 3090s, e.g. Seasonic Prime (including derivatives and rebrands), and Seasonic Focus (and rebrands)

Nvidia was surprisingly conservative with their power supply recommendations for this gen. I guess they didn't want to scare people off with crazy requirements.

 

It certainly doesn't hurt to go a little beyond the recommendation for safety.
