Not sure if psu works

Solution
Paperclip will tell you that the PSU is able to turn on.

It does not tell you if the voltages are correct, does not prove that it can output the amps needed to power your system at startup, idle, or full load.

The paperclip is still a good test, but the test is to see if it fails, not to see if it passes.
