5 Volt Supply Any Good?

[MichaelHiFi]

I found a power supply going through my closet. I believe I used it on my Squeezebox 3.

 

Wonder if its worth using it on say a music server hard drive or my EtherRegen? If it's better than OK, I'll staple a power cord and or Furutech IEC (have a few in my toolbox)

 

Not electronically inclined so here's a few pics. Thanks!

5V is not enough for the EtherREGEN. Must be in the specified 7~12V range.  
Please do not use any random out-of-case PS with EtherREGEN.  If we find damage caused by PS (and we can tell), it will not be covered under warranty. And a new EtherREGEN circuit board is not cheap! 

No worries, I won't use it on ANY electronic device before checking requirements.
