So recently I bought a new corsair TX650M to replace my old PSU ( which was a corsair VS450) as I will need it for my new parts I will be getting shortly.
I plugged in all my components correctly, checked all cables and used the cables supplied with the unit itself, the system turns on, all fans spin and RGB lights up too and everything seems to be working, however there is no signal on my monitor and the CPU debug light on my motherboard is illuminated, I then took out the TX650 and plugged back in my VS450 and my system was back running like normal.

I have tried resetting CMOS, removing a RAM stick and none of that has worked.

Specs;

MSI B450 PRO M2
R5 3600
GTX 1080
32GB DDR4-3200MHz
