1 cable with a dual plug
so you will be doing more then 220 watts on one cable.
that is not good.
I have 3 apollos. I run 2 off a 450BT and one on a BR. All run in balanced mode constantly with breaks here and there.
I really don't have any any problems with those power units at all. A little trick I did and I don't see a lot of people talking about this ... fan in-front of the miner. I can run balanced at 15% internal fan and keep the CPU miner under 67c.
A simple Thermalake T1 USB stand alone fan in front of each unit drops miners fan requirement and makes even less noise.
