Has anyone found a link for a UL certified PS i can use with the D3 to send to GW?  I've purchased quite a few miners from GW, but i'm also sending them a couple i purchased directly, and they say i need to supply a UL certified PS with them. Does anyone know where to acquire these?   Not sure if the normal Ti type will be UL certified, most don't list that in spec, or most don't have it. Not sure where to source. Can GW refer us to a manufacturer?
