Your PSU won't turn on until the motherboard tells it to, and for that to happen it has to be connected to the motherboard.

Also, some smarter PSUs won't turn on the fan until they actually get warm enough to need it, even if they're on. The only real way to test they work is using them in a system, unless you have proper dummy loads and meters.
