Trouble booting

[Tokkoa]

Hi 

 

So as a preface my hardware is the following

 

RTX 2060 MSI 6GB

MSI Pro Carbon Z390

I5-9600k, Corsair Capellix AIO Cooler

250GB Samsung SSD, 2TB WD HDD

Phanteks Digital p500a case

Crosair Pro Vengeance 32gb 3600mhz

Corsair RM850x Power Supply

 

The issue was that my pc was randomly shutting down instantly then rebooting, during Idle in windows, and gaming, also sometimes during boot, 4-5 time turns off and on and so on forth, repeating. I got a new power supply, now when I turn on the PC, the fans spin crazy fast and the Ram RGB wont light up, and no display detected for my monitor. I tried plugging the Display Port cord into the Motherboard and met with the same thing, no display on the monitor. No beeping errors during boot, the pc will just sit there and spin the fans and make alot of noise for a long time. Also, after changing the Power supply, the lights on the case fans no longer turn on, don't know if this is coincidental. Even tried unplugging the HDD to no success. Issues did not arise until after the Case, Ram and Cooler was bought and built. Everything else was from previous PC, no issues prior.

What power supply did you change from? Which cables did you use. The old ones or the ones that came with the RMx?

Thermaltake Toughpower 750, swapped the old cords out with the new ones. Currently the RMx cords are in my PC.
