At 70% mechnical efficiency, 300w of power is wasted...it's like buying an extra PSU just to plug it in and do nothing.
At this rate of energy consumption soon enough we will have to harvest fat from obese kids around the world and convert it to biodiesel.

1) I assume you're making an assumption on efficiency as I don't see it on newegg or the mfr's website. But how else would you get 1000W to run your Quad-Dual-SLI watercooled setup? I thought 75% was a run-of-the-mill efficiency (or call it 70) so what's it matter? One 1000W case or 3 350W cases... ? (I assume you're being facetious, no virulent defense needed!)
2) You almost make this sound like a bad thing...

Not so sure this belongs in a hot deals forum as it's probably the worst price: Quality ratio possible.

you're assuming the psu would be at maximum output continuously. very few units are actually designed to withstand that sort of ordeal.

Obviously it'd be quite hard to cause that kind of load, though possible to get near enough on 12V rail if someone went overboard with peltier cooling everything.

Even so, all PSU are designed to sustain their actual output and if the wattage rating on the label isn't the same value it is fraud. A "peak" output that it can't sustain would be a figure HIGHER than what is on the label. While a label could have separate numbers for peak and sustained, they can't list ONLY peak figures.
