That's a borderline maybe. If the player has only one disk drive, and the power supply really can handle 1500ma with regularity, and every bit of componentry in the player and the adapter are all within spec, then theoretically it would work. If it were me, I'd be looking for something beefier if I wanted it to be reliable. I take it you read the spec and you see that the power supply you linked does in fact meet the spec, but that it's borderline? Anyway, if I were in the market for a power supply, I'd order one of the units linked there and skip that particular ratshack unit.

The plug you quoted appears to be the right one, however.
