the power supply of my customer's RND4000v2 - READYNAS NV+ v2 is broken and I promised to find a replacement for that.
The label on the power supply indicates the output with 12V 7.5A but since it's a 4 pin plug I rather think it's a 12V & 5V PSU. Also the 7.5A is rather untypical.
I found some similar power supplies with 12v 2A and 5V 2A lines and 60W in total. Would that be enough?
Can I find the exacty specification somewhere? The hardware manual doesn't even mention any power related values.
Actually, the 4-pin is VERY typical of a 12V supply with >5A output. It's just that the need for them is lower. The barrel connector is used with ≤5A supplies, whihc are more typical. The problem is that not everyone uses the same pin-out. You need one where pins 1 & 2 (on the side with the key/flat spot) are +5 and the other 2 are ground. Beware that some who sell them hide which it has, so avoid them. I know there are some specifically listed on Amazon and eBay as being for the RN104, and those are compatible with the NV+V2.
A Google search with ReadyNAS and DIN Plug will yield many forum discussions that give specific brands and models that work. Don't bother with the search function in the forum itself, it's abominable.
