I'm not so sure about that. Unregulated power supplies put out higher
voltages when not used at the design load.
If the no-load voltage of the psu is less than the terminal voltage (ie
one that will kill it!) of what you want to connect, then you're
probably ok. Otherwise; your call ;-)
(It'll probably only be a few volts higher at 300mA though).
You'd definitely be safe with a >300mA regulated psu...
