What power supply will be good for this? No info on BMT about how many Ampers must go in PCIe line. And miner needs 590W ? So we need about 700W PSU..

now, first batch of S5 sold out in 12 hours. good luck to you guys.
Nope, not sold out.
Let me put it to you: BMT are unsure about the stability of the S5 and they have only sold a few to test RMA requests.
I guess we'll just have to wait and see if they can beat SP-Tech 1 (one) voluntary RMA in Thousands...
dude, you are really working hard here, I hope you get your free sample of sp20.
I don't accept free units, all of my miners are paid for. thanks for your concern.
then you are really stupid.
WHO THE FUCK DO YOU THINK YOU ARE TO ADDRESS ME IN SUCH A MANNER?

only see the wrong design from the very first SP20 . There should be a 8x PCI-E.
true. maxing out power rating for the socket is very wrong decisionThe manufacture takes 20% margines over the 288 Watt rating.

Tupsu, you seem to have a requirement to post only half of the story across many threads. The problem was caused by user error, as you can see here:
2 is many treads?
I posted here, and to your personal S5 topic
I do not see user error.
you can see the problem. the user put the wrong cables.

The design is correct, each Molex connector is rated up to 288 Watt. We've tested much higher. Note that it's PSU output rating, not "at the wall".
We offered the customer RMA freely to investigate, he refuses out of " fairness", since he belives the problem is with his cables.
It's the first and only reported incident.

Today I bought 12 pieces Antminer S5
I trust them today more than SP20 , especially after seeing this picture. Because they have 4 PCI-E slot, For 600W.
SP20 has 4 PCI-E slot for 1200W (Max)
I have 3 x SP20 and
6pc SP20 purchased by December 17, to get my hands probably 29.12
I also have a 5pc KNC Neptune, with no burnt PCI-E slot.
The rest are all Bitmaintech production. (37x S3, 6x C1, 2x S4 )
It would be seen that picture before, then I would not have ordered more SP20.

Tupsu, you seem to have a requirement to post only half of the story across many threads. The problem was caused by user error, as you can see here:
1.all 288w but only use 230~270w report from ASIC stats
2.no (but cable that of the picture is)
3.I cant tell, maybe 10AWG or 9AWG
4.32C report from another working SP20
i don't wanna go RMA because i think the problem is on my plugs, if you give me a new one that is really not fair to you, i just want to keep this miner cover in warranty after i replaced the socket myself.

Today I bought 12 pieces Antminer S5
When I went to sleep they were "Up Coming" and when i woke up they were "Sold Out".
They are a nice little step up in efficiency but I didn't expect them to go so fast.

sold out allready
glad I got my order in!

Will those who opted for L1 refunds in full bitcoin receive them soon? Will place an order if I get the refund.

There's 14 steps not 15. 0.64v at 9v.
Hard to tell from the pictures but according to multiple quotes by Bitmain in this thread, there are 30 chips per board. 15 steps, as you'll see if you look more closely (bottom left hiding in the shadows).

Wow,
Thank you for paying detailed attention to our product photos!!!
There's 14 steps not 15. 0.64v at 9v.
If you look at the photos of the back there's level shifting.

Also, the S5 has 15 steps in the chain (30 chips) so 9V would drop to an even 0.6V per node.

I don't know if the S5 uses isolated or level-shifted comms, or some daisychain implementation like the Bitfury chips did. Haven't scrutinized the PCB photos enough yet to make an educated guess.

I sat down one morning last week and worked up a rough design for relatively-low-bandwidth (maybe good for 1MHz, which should work for any practical miner's UART or SPI) logic level shifters and a constant-node-voltage current dump circuit which could, in theory, be used to chain any kind of chip with any arbitrary voltage. It's probably just a loose implementation of ASICMiner's proprietary PMS01 chip, which looks to be a pretty nifty device.
We're also contemplating working up a high-current (and hopefully high-efficient) inline regulator to make undervolting string miners easier off existing 12V PSUs. The basic design coincides with some other projects we're working on anyway. Something like that would be handy to strap some S5 (or Prismas) behind here in a few months.
