New GPU, Power Cycling

Hey there!

GPU - NVIDIA 2060 SUPER, reference card

CPU - Intel i7-9700k

PSU - Corsair CX750M

MB - MSI mpg z390 ga

RAM - 2x 8GB Corsair Vengence @ 3000

SSD - samsung 970 plus m.2 500gb

So I'm having a little bit of a confusing issue. Just built a new PC 8 days ago. Had to wait 7 ish days for the GPU (NVIDIA 2060 super, reference) to come in. In that mean time I played off and on with my old GTX970, had no issues. Keep in mind it was light use, not extended periods of time.

Get my new card, slap it in, almost immediately the PC shuts off like my power went out. Everything black, no BSOD, no message. Computer then reboots like nothing happened. Event viewer reads Kernel-power 41, aka unexpected shutoff. This happens multiple times, with varying intervals of time between episodes. Sometimes can go an hour without doing it, sometimes its continuous on startup etc. Typically it happens just while browsing or sitting on my desktop. I go through NVIDIA tech support for a lil while, ends up wanting to RMA the card.

I put my 970 back in, in prep to RMA the 2060 and it shuts down one more time. The next day (today) I've been on the computer for over an hour and it hasn't occurred with the 970 in the machine. Thinking it might be an issue of power dips with the PSU possibly, and since the 970 might require less power it just isnt running into it as much?

Should I RMA the card or go for a new PSU or something else?

Thanks
