Mr. Short

Thanks all, i replaced the power supply and the system works, without issue!

Ok so, here is what has been going on, I have gone through 2 x570 motherboards and am now on my third. First mobo: Aorus X570 ultra random freezing issues no matter the operating system, sent that one back for an exact replacement. Second Mobo: again Aorus X570 Ultra rebuilt custom hard tubing loop, then nothing would power on but the RGB lights on the RAM which is thermaltake tough ram (white) at 3600MHz. I contacted AMD for an RMA on my 3900x sent the motherboard back. Now i have the current configuration: Mobo: MSI X570 GodLike(New) Proc: AMD Ryzen 3900x(New) RAM: Thermaltake ToughRam 32GB(4 sticks @3600MHz) PSU: EVGA 750 80 plus bronze GPU: MSI 2080ti Ventus, replaced with ek waterblock cooling: EKWB XE 480mm rad with 8 fans push pull config with one D5 revo pump with a massive res New symptoms, IF the graphics card it unplugged the system turns on but gives a cpu error (I have already flashed the newest BIOS). Plug the graphic card into power and I get a split second of power then everything turns off. I suspect a failing Power supply, this is the only part all previous configs have in common so i have ordered a new power supply. Is it possible once I get the new power supply that the CPU error will go away or unlikely as the power supply might have fried it..? The thing is I believe the power supply works but fails under load, when I plug into a tester it gives all correct voltages. But plug into my system and boom nothing. please help. PS@Linus is this invision software? if so nice choice, can't tell i have built websites with it in the past but its been a while.
