I wouldn't be so sure. I think they can squeeze 2 TH/s out of 1100-1200W.

2000G * 0.7W/GH = 1400W MINIMUM...OK... Huh

The assumption is that the S4 works with underclocked/undervolted ASICS to reach a better W/GH ratio, I would assume somewhere between 0.55 and 0.65 W/GH, so one 1300/1400W power supply could indeed do. But of course we'll not know for sure till @BITMAIN reveals the exact specs.

still, they wont give you something like
Evga 1500w Platinum Cheesy

and, btw...
5units of S3+ = 355w x 5 = 1,775W

i assume S4 will be around 1500w - 1700w
they wont waste chips like that..
they better selling chips like avalon do than planting so much undervolted chips
and sell it so damn cheap Grin

they're not doing charity here buddy Cheesy

In the U.S. a standard electrical socket is rated at 1600w max. I believe, so I don't think they'll go over that. Would be nice if a 1300w single power supply would be able to handle the new S4 with the EVGA G2 so cheap right now.

A 20 Amp 110 v circuit can handle a continuos load of roughly 2000 watts, not 1600. Give or take a bit of course. Most new construction uses 20 amp breakers.

For continuous load you should not put more than max 1650w on a 20amp breaker, or the breaker will get hot and eventually burn out. Just like your tires going on the road 100MPH all the time. The formula for continuous load is subtract 25%. If your wire or breaker feels to hot then you are doing something wrong. 2000W is a no no.

We will just have to agree to disagree there. If a breaker is rated at 20 amps load at 110v it will certainly hold 1920. I also speak from experience here. Long term loads of 1800-1900 months on end. No issues. But yes the breaker will get warm.
