Hy dear Bitmain and dogie, unfortunately the "new" S4+ has no significant improvement in power to hash ratio and on my personal opinion a decrease in attraction for home miners in Middle europe, US and other countries above €$0,15/kWH. If i may post a wish for a S6 or S7, this would be 0,25W/GH and a noise level below 30db. Technically this should not be an issue for a legit company as bitmain is  Kind regards, elrippo

I don't know if I would agree with all of this.  I think home miners are starting to look at 220/240 so I'm glad to see them jump into this level.  It allows for a lot in future. As far as .15 KWH in euros you might look into hosting centers I think you will be able to get it cheaper.  Also avoid I'm guessing a Europe vat depending on the location of hosting you choose.

Bitmain, please treat the S4+ and it's users better than you did the S4's.

I personally am a fan of hosting my hardware at a location that i have immediate access to, virtually as physically. Unfortunately other countries have a quite huge advantage in terms of power cost and taxiation. If i remember wright, this is a community driven effort, and it should be possible, nearly possible for everyone to dedicate to it. With the current FIAT ratio and costs to mine, several countries if not continents have a disadvantage which can be partially compensated by technology. Bitmain seems to drive this as a big player in the industrie and serves home miners, and before i write further, i really appreciate this, so i do not think that this is technically a issue, this is more a strategic and philosophic state. I don´t have to mine at 220/2240 here in Middleurope with a rasing diff of 3%. It starts getting profitable above 335/340 for one year, maybe 18 months.

That's the underside, pressed tight against the heatsink. You can see from the heatsink picture that those areas are fully enclosed and not exposed to the air what so ever.

Mini Review: I have a couple S4 Plus units in hand that I have been running for about an hour or so. Getting about 2550 GHs on each one, running on a pool that is known to lose some hash rate. Measured about 6.2 - 6.3 Amps / 12.5 Amps for the Pair on 220v (235v) = 1470 Watts Each at the Wall. So I personally am getting about .57 Efficiency which is slightly better then advertised.   About the same sound / noise level of a normal S4, only hear the high pitch PSU fan if very close up. I am getting some vibration noise, from both of them, which is unusual, as I never had before in any S4 Units. Overall, Not Bad, A tad overpriced. People want the S6 with the new chips, this is something at least until then. Anyhow I have them up for sale if anyone wants them shipped out today from New York.

I'm convinced the S4+ is just an attempt to make the S5 look like a better value, so they'll sell more of them. This is a marketing trick to make the lower priced product seem like a better value.

That could be and wouldn't surprise me.  Just the same if the S2 upgrade kits ever get released with the initial specs the S5 and S4+ miners won't sell.

I don't know if I would say that.  If you had a warehouse or huge operation this would be a nice product as far as the amount of hash it brings. With not being 110 its not a product for all, but there are some out there that are it's "ideal" customers.

Ideal customers, anyone that cares about power efficiency and has plumbed 205V+ in already? I paid all of $150 to have an electrician drop in two 240V 20A circuits and they've been paying for themselves with EVGA, LEPA, Antminer, other PSUs running an average of almost 10% more efficient.

And your $150 get's thrown right out the window when you realize that the s4+ is an extra $200 more than the equivalent 2 S5s. And so your 240v line is saving you what? 3 cents an hour?

The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage. Does this mean a Home in the USA can not use this as its only 110 service?

That's exactly what it means.  Unless you've got your home wired with some double pole breakers that'll give you the 240V, this product is not for you.

Aren't American Dryers 220v?

Good luck convincing the little lady that she's got to hang your clothes out to dry because you're replacing her dryer with some miners .
