Installed brand new PSU and two of three monitors don’t work.

[Orpheuss]

Hey guys, so I just went to Microcenter today to pick up a brand new power supply for my crazy system because my previous Antec 1300W couldn’t maintain the power. I got a Corsair AX1600i so that I finally don’t have to worry about a thing and when I started up my system for some reason only 1 of my three monitors works out of only one port. Any help? I already installed drivers too

Did you change anything else, other than the PSU? Is this a new OS install etc?

A PSU change alone, should not impact the display outputs in any way.

How are they connected (GPU to Monitor) HDMI? DisplayPort? DVI etc?

Take a look in the Nvidia (or AMD) control panel for settings/displays.
