Question How to dual psu?

[PCbest]

With the release of the 4090 and upcoming 4090 TI and 13900ks. I'm going to need dual psu i believe so i can SLI 4090 TI's. I know that I'll need two psus most likely but I'm wondering how to set that up as well as I want to confirm that I'll need to run one PSU to a separate outlet as to not overload it.

The real solution is to get ONE PSU of appropriate size.

Separate outlets in the same room are typically on the same circuit and breaker.


If these GPUs really needed 2x PSU, that is seriously limiting their customer base.

Can't you just get one big one like:

In addition, what leads you to believe you can SLI 2x 4090 ti?

What makes you think the 4090ti will even support sli?

You mean NVlink? From what I've heard RTX 4000 doesn't support NVlink.

Actually in the USA you can't do this. Any PSU above 1600W requires 240V outlet.

Can't do 'what'?

2x big PSU on the same circuit?
No, you can't.

But, what is the need for the 2x PSU?
Not for the 2x 4090 ti in SLI, because that is not a thing.

Because of course you can
