Hi, Thanks for your reply. My question was more around whether buying a "random" 12V/5A power supply from eBay is sufficient, or if their are any issues I should be mindful to avoid. Particularly...

I've just purchased a second-hand Archer C3200 from eBay (We have about 15-20 devices online at a time so I thought a tri-band access point might help)... However...it was sent with a 12V 1A (12W)...
