Digging the hash rate:

Hashrate Average   Weighted Shares
3 hours   580.52 Gh/s   1459765
22.5 minutes   609.41 Gh/s   191550
256 seconds   633.50 Gh/s   37759
128 seconds   707.89 Gh/s   21097

Wonder if just 1 Jupiter

I doubt they will be supply anything hashing at 707.89 Gh/s, even if it can do that. They have 1000's of 850w PSU and told their customers to buy that spec, so things will be tuned to work with 850w.

KnC Cole on CoinDesk:

We have 22 stations manned by assembly experts to make sure we can keep on top of the orders and have the boxes ship as soon as possible.

Our engineers have also been working through the night to tune the power consumption and the latest test indicates that we will have a much better result than 1.4 watts at the wall.

i.e. they are tuning power consumption, not maximising hashrate.

How is this tuning done (software ? ) and is it possible to retune the rig yourself without any real knowledge . I have a 1200w PSU

Even if you have a 1200w psu, I doubt the chips could handle that much. Let's say they are stable with 65-70 celsius at 850 to 900 watt, you would need to cool down everything that goes further massively since gained performance does not equal the same amount of heat generated. 300 W on 4 chips would be around 75W per chip, that is a lot more heat to dissipate. You could propably manage that with watercooling, but even then there is only so much voltage a chip can handle before going awol.
