You need to use Collectd with Thresholding, not Pollerd

A good place to start for this is
http://www.opennms.org/wiki/Thresholding

You are just using an SNMP Poller to identify the state of a service called Cisco-PowerSupply-Monitor, which can be only one of two states, up or down, depending on the evaluated value returned.

If you wish to, for example, get an alarm when the voltage or current drops below or rises above a certain defined value then you use Thresholding.

As far as I know Thresholding is done in memory from collected values but the configuration for data collection means that RRD Archives will be created and written to anyway.

No unless it fails the SNMP Poller evaluation and the value is in the service outage event as the reason template code,
but you asked originally

"How can I see what values opennms gets from the nodes?"
You would use Collectd and then create RRD graph definitions for that collection for viewing the data in graphs

"Is there any possibility to check if the new configuration works, gets the correct values?"
By using Collectd and either creating the graphs definitions or using rrdtool to view the RRD archives
