Hi, I have a problem with my PC. Whenever I try to turn it on, the PC loops on and off and won't start.
The specs:
CPU: i9-9900K
GPU: EVGA RTX 2080 TI Black
RAM: DDR4 T-Force Nighthawk 4x8 GB
HDD: Western Digital WDC WD2000FYYZ 2TB
SSD: Samsung SSD 970 EVO 500GB
MOBO: MPG Z390 GAMING EDGE AC
PSU: TT ToughPower GF1 850W
CASE: TT VIEW37 ARGB
The case has a controller for 3 fans: 2x20mm frontal. 1 x 12mm back.
I have checked every component and they're OK. Also, I checked for electric ground problems and the PC is grounded.
When I disconnect the SATA power from the WD HDD, the PC starts and when I disconnect the SATA power from the fan controller, the PC also starts. The problem happens when both the HDD and the fan controller are connected. Considering that, the method I use to start the PC is disconnecting the the fan controller and when the PC boots, I connect it again.
So this are the possible causes:

So this are the possible causes:
- The PSU is not delivering enough power: I don't think the PSU is at fault, since it has 850W output.
- The HDD is consuming too much power at boot for spin the motor drive: I don't think so, I tested the HDD in other PC with a lower PSU power and it started correctly.
- The fan controller is damaged, maybe some internal short-circuit that causes high currents to flow and the MOBO protects itself not starting the PC and causing the loop.
Thanks.
