I also find that one of my PS does not like the Hyperion 120i (w/a123 support). It appears that the Hyperion has a large surge at powerup. Only way I can get that supply to work is to Power up supply then plug in Hyperion. If I plug in Hyperion before powersupply is up and running, the fan will just do a half rotation and shut down. (That PS is rated for 15 AMPS on 12V)

I have other cheap units that are rated to 10 amps, They work Just fine with the Hyperion. Of course they limit my charger, which is not a issue as most of my packs are 3s.

The only cells that I have that push my charger are my A123 packs which I am now charging at ~15 AMPs :) 3S pack. (zip charging with DB-terminator)

Also if you notice the PC supply voltage sagging onthe 12 Volt's try putting more of a load on the 5V lines. It helps. I find a 3amp load on the 5Volt line really helps keep the 12volts nice and stable.

Last but not least. If your 12volt wires are getting warm you should be double or tripling them up. I twist 2-3 black together, and 2-3 yellow together. My wires never get warm. If yours are still getting warm... use 4-5 wires.
