Maxtor 3200 160 gb Power Supply

Does anyone know where I could find a power supply switch for a maxtor 3200 personal storage. Power supply switch is DVE brand DAS 36w-12 24. I have only been able to find ones that cost over $100 or ones that have a 2.5 amp output i.e. models ending in 12 30. Would this work or not? Any help would be greatly appreciated.
