Power & unexpected shutdowns
Record when power is lost.
Note whether the whole computer turns off or only the display. Check the external power connection. Never open a power supply: internal components can retain dangerous voltage. Have internal power faults inspected by a qualified technician.
Find your exact error
All Power supply errors →PSU-OVERVOLTAGE
The power supply supplies a higher voltage than specified. Risk of component damage.
Power supplyPSU-INSUFFICIENT
The resource does not have time to cover the consumption of all components. Causes resets.
Power supplyPSU-RIPPLE-NOISE
The source produces higher than permitted supply voltage ripple. It causes instability or damage to the capacitors on the board.
Power supplyOCP-TRIGGERED
The source detected a dangerously high current draw on some of the lines (typically 12V) and immediately shut down the computer just to be safe. Use the steps below to track down and fix the cause.
Power supplyCOIL-WHINE-EXTREME
The source or graphics card emits a high-pitched, annoying buzzing sound, especially under load or at high FPS. It sometimes comes down to resonance of coils in power cascades (a common physical phenomenon).
Power supplyOVP-TRIPPED
The source immediately shut down because the voltage on some of the branches (12V, 5V, 3.3V) increased dangerously. It's most often caused by fluctuations in the distribution network and poor Quality Resource (Tier F).
