Is an underpowered PSU still good to use?

Sorry for the newbie mistake huhu but is there any chance of a second life for the psu? I have purchased an aerocool 500w but I recently found out that i need at least 650w for my build. I intend to sell the 500w but is it still functional for the second user given that it's going to be installed for the right build?
