Review: IMPROPERLY WIRED ADAPTER - My D-Link NAS did require the adapter, but upon failure of the supply to power the NAS, I did some pin poking and found that the adapter itself was improperly wired. AS DELIVERED, THE +12 LINE FROM THE SUPPLY WAS LEFT IN ITS ORIGINAL POSITION, AND THE +5 LINE FROM THE SUPPLY WAS TIED TO GROUND! THIS CONFIGURATION WOULD BE INAPPROPRIATE FOR ANY D-LINK NAS! (See illustration). The net effect of this improperly wired adapter was to place +12V on the +5V input of the NAS, and to short the seller's power supply’s own +5V output to ground. As you can WELL imagine, neither device was very happy with this arrangement. I will be contacting the seller in an effort to come up with a satisfactory replacement NAS.
Review: Four Stars - Worked as intended.

## Questions & Answers

**Q: Is this the correct version that can supply up to 3a on both the 12v and 5v supply?  or can it only supply 2a?  why is this covered in picture?**
A: Yes it is. The picture is just a generic photo of an UpBright adapter and I think you'll find the input and output voltage and current covered up or illegible in the phohto in most of their ads. The one I received through this ad was a JenTec JTA0512 which lists the output as "DC Output: +5V/3A, +12V/3A". Mine was for a DNS-323 and it works great so far (~ 6 months).

After trying to get a response from DLink to replace the power supply on my NAS, I finally gave up and bought this after-market item. Works great!
