Hi, I recently purchased a Seagate Expansion 8TB External HDD (STEB8000100) from amazon which arrived with a power supply with US power prongs.  The US power supply that was included has the following specs:


INPUT: 100-240V - 50/60Hz (Max 0.7A)


OUTPUT: 12V == 1.5A


I know I could purchase a travel adapter to convert the US prongs to NZ prongs but I actually have a spare NZ power supply (from an older WD 5TB External HDD) which has the same connection and all the same specs as the Seagate power supply mentioned above except that it states 0.6A on it rather than the Seagate's Max 0.7A spec.  


Does this matter at all or will the WD power supply work fine with the Seagate External HDD?  


Thanks, hope that makes sense.   :)

In my experience, power adapters for virtually all WD/Seagate external drives are interchangeable, I'm pretty sure you'll be fine.

Ignore the input - concentrate on the output - 12VDC x 1.5A = 18W. Since you need 12VDC, then only the 1.5A is optional. Try to stick and a minimum, although you could probably go to 1.2A and still be fine. There's no maximum because the unit draws only what it needs so if you had a 12VDC 5A supply it's still fine. Just check the polarity is the same although it's rare to fine one that is not centre positive.
