From the looks of it, it appears that the "controller board" is only giving idle current anyway. With this one, or one like it, from me, you would still need to buy or build a controller. In addition, I will send a 110V fan along so that you can cool the laser.
Or I have another 448nm that works with an internal controller (on the PSU)
I don't have any extra PSU on hand. Just search up uniphase and/or cyonics in eBay. They are listed all the time.
Just like with all things eBay --
patience will get you a deal
