I had a perfectly working 12 strand of flexstips working a few days ago. put on a power supply instead of the dc power as I need the DC power elsewhere and I think the pc power supply was doa...so now I put a different dc power supply on there and having some issues powering more than 6 strands. Its just a 32amp PS....vs the old dl380 PSU that did 50amp. two questions, is 32amp enough for a 12 strand tree and I have other issues? can I any way put on a less powerful PC power supply and a DC power input at the same time on the active hub?
