Solved Dell support was able to send me a replacement 3080 and the system is running fine now. Kudos for the fast shipping Thanks for all the input. 
My R11 crashed to a black screen while playing Valorant and I haven't been able to reliably use it since. Half of the time it won't even POST, but sometimes it does and I can get to the desktop where it will usually crash within 10-15 minutes, the screen will randomly flicker too. The fact that it POSTs sometimes but not all the time seems really strange. When I can get to the desktop, loading up a game or the Heaven benchmark it will run for about 20 seconds and then crash. The screen freezes and then eventually goes black. I've only had a keyboard and mouse plugged in while I am troubleshooting, and I disconnected the internet while clean-installing drivers.  I'm not getting any bluescreens when it crashes it just cuts to black.  I've reformatted the system twice and have used DDU to cleanly reinstall the latest Nvidia Driver and the crashing persists. I looked inside the case and made sure all the power cables are secure, took a stick of ram out, reseated the ram, put the ram in different slots, and put in different ram, and it's still crashing all the time. I have MSI afterburner running when I load up Heaven benchmark and the temp is usually only around 60c when the crash happens.  The reason I think the 3080 is the problem is because I took it out and put it in my old system which has an 800 watt PSU, so it should be more than enough, and the same exact crash happened. This system is stable when my rtx 2060 is in it.  There's other weird behavior too, like the system won't recover from a restart, the screen turns black and it never comes back until I completely cycle the power.
