How Can I Check My Psu -

This is a critical failure. Turn off and unplug the PC immediately.

The first step in checking your PSU is to perform a visual inspection. Look for any signs of physical damage, such as burn marks, melted plastic, or swollen capacitors. Check the PSU's casing for any dents, scratches, or corrosion. Also, inspect the power cables and connectors for any signs of wear or damage. how can i check my psu
