What kind of power supplies are you using? Power cables are usually rated in amps, but do not take power factor into their calculations. If a power supply has a PF of .8 then you'll actually be pulling 20% more Volt Amps than the watts you think you are pulling. Good power supplies can have a PF of .9 to .95, big difference.
Moral: You have to size your cables and plugs for volt amps more than watts. I've seen this happen a number of times.

I'm using the 1600W power supply from Halong. I'm not sure of their PF?
