+Check Hardware (Power Supplies).
+
+=over 8
+
+=item B<--component>
+
+Which component to check (default: '.*').
+Can be: 'psu'.
+
+=item B<--filter>
+
+Exclude the items given as a comma-separated list (example: --filter=psu).
+You can also exclude items from specific instances: --filter=psu,1
+
+=item B<--absent-problem>
+
+Return an error if an entity is not 'present' (default is skipping) (comma separated list)
+Can be specific or global: --absent-problem=psu,1
+
+=item B<--no-component>
+
+Define the expected status if no components are found (default: critical).
+
+=item B<--threshold-overload>
+
+Use this option to override the status returned by the plugin when the status label matches a regular expression (syntax: section,[instance,]status,regexp).
+Example: --threshold-overload='psu,CRITICAL,^(?!(ok)$)'
+
+=item B<--warning-count-*>
+
+Define the warning threshold for the number of components of one type (replace '*' with the component type).
+
+=item B<--critical-count-*>
+
+Define the critical threshold for the number of components of one type (replace '*' with the component type).
