What is UVP-TRIPPED?
Undervoltage protection (UVP) activated ranks as a critical-severity power supply unit (PSU) issue in our database. The voltage fell below the critical limit, the system shut down as a precaution. Another common trigger is leaked capacitor. Use the steps below to track down and fix the cause.
Common Causes
- Blackout or severe voltage drop in the electrical network
- A weak source cannot maintain the voltage at the load
- Leaked capacitor
Step-by-Step Fix Guide
-
1
Get a power supply with a strong 12V branch (single rail)
Get a power supply with a strong 12V branch (single rail) resolves the majority of UVP-TRIPPED cases on its own, making it the logical starting point.
-
2
Check the wiring of the apartment
Not every case resolves on the first try; the steps that follow cover rarer psu instability situations.
-
3
Underclock the components for the test
"Underclock the components for the test" is the next step worth ruling out for UVP-TRIPPED.
Commands & Diagnostics

Frequently Asked Questions
Blackout or severe voltage drop in the electrical network accounts for the majority of UVP-TRIPPED reports; a weak source cannot maintain the voltage at the load and leaked capacitor come up less often but are documented.
The fastest fix is "Get a power supply with a strong 12V branch (single rail)". Only move on to the later steps if UVP-TRIPPED keeps coming back.
Treat UVP-TRIPPED as urgent — it's flagged critical severity, meaning repeated occurrences risk data loss or hardware damage.
In most cases, yes — the guide above resolves UVP-TRIPPED without a clean install. Treat a reinstall as the last resort, not the first move.
