I got my S3 batch 4 yesterday and got it online this afternoon. Running for 6 hours now at 440.78 GH/s on Slush's Pool. Wattage at the wall is 357.9. Relatively quite and putting out about as much heat as a Block Erupter Cube. I couldn't find the IP address in my router, so I used a program called ipscan and found it. Set up 3 pools for failover, disabled the beep and Bob's your uncle. I'm using a Corsair 850 with just two plugs at the rear. Easy setup, no x anywhere and a solid performer. Early delivery to boot. Experience is excellent so far. Looks like a good idea to order another.
