Re: AntMiner S2 1TH/s Miner (1w/GH/s) Batch 4 is open for sale

How can the unit draw 1Kw and only have a 1Kw PSU ?

If you buy an s-2 I advise you to pull 1 blade and list it on ebay for a high price. say 350 usd. Slowly drop the price if it does not sell.

As long as you get more then 250 the price is not bad. having 9 blades will allow the stock psu to not fry and die. getting 250 or more for the blade will make up for the lost hash.

do the math what does 100gh earn.
and the math shows the 100gh lost does not pay off 250 usd so selling it for 250 usd works out as the best move.

bottom line is the s-2 is not a great buy. it needs to be priced lower

Bitmain is a shrewd businessman - that is clear. He knows at this price the S2 will not ROI - watch for the price drop coming soon which will blow the S1 out of the water. This is typical businessmanship. I like this guy.

keep in mind the cost of chips - there are 10x as many chips in an S2 as there is in an S1. If the chips still cost bitmain >$1.50 each (~$0.50/GH in an antminer S1) then they are a significant portion of the S2 price. add in a nice LCD, quality case (still tweaking the card support of course), and a PSU - a price drop to $2000 after coupon with delivery before the 14th of may would be fair, and a price I could afford a small premium over the S1 to buy. (fewer cords and better stacking for bigger mining farms)
