Best power adapter for older G-RAID

I have a used G-RAID 4TB 0G02484 which I bought via eBay but for some reason many eBay sellers often sell a drive without the AC/DC power cable. Weird, but my bad for not asking first. What is the best 12V 4 Amp power adapter to buy that is still being made? BTW, I don’t have Thunderbolt which is why I bought the older Firewire and USB 3 unit.

You can buy our own adapter that is made for that on multiple retail sites. Search for 0G02745
