I have 2 of these 220V server power supplies (no idea what PSU really stands for, and that's fine with me), and they have no fan and they have 8 guage wires going to them and wow, they seems efficient compared to the black box PSU devil tatoo'd XTREME!!!! Brand of PSU that I got at the PC builder shop.      The 220 power supplies are a bit trickier to setup, but no more breakers busting up twice a day, it's just solidly hashing away at moderate temperatures.

I wonder if anyone can tell me what a laser beam IR remote temperature reader gun thingy should cost.   Like what should I pay?
