(specs below) I started noticing A problem when I added quite a few USB devices and it would cause the computer to shut down, so I just unplugged a few and it worked perfectly fine, at the time I had a 750w EVGA PSU, then I added 32 additional gigs of RAM (yes their exact same model) and went into the bios and enabled the AI overclocking option, and it would work however randomly would crash the system. so I turned the AI overclocking off and took out the Extra set of ram thinking it was a psu issue. I got a 1200w plat hoping to fix the issue and at least use the extra ram I bought. Was doing good but now it is disconnecting some but not all of my USB Devices randomly, I have to turn the PC off and back on multiple times in order for it to work

get Speccy from here; https://www.piriform.com/speccy/builds
in Speccy, click File > Publish Snapshot > Copy to Clipboard > Close.
now you can paste (Ctrl+V) that link into a post.
One component Speccy doesn’t cover is the Power Supply Unit, so please also include the make/model of the 1200w PSU.

how many USB devices are we talking here?
and what sort; HDD storage, headphones, speakers, USB memory sticks, etc?
and does it play up as soon as all the USB's are connected, or some time down the track, say 10 minutes or something?
