Giving advice about electrical safety when you are not qualified / certified to do so is a crime in the UK (and many other jurisdictions). Latif aka dogie, your only qualification is taking pretty pictures of mining rigs & waffling on about them plus forging education credentials and that does not qualify you give advice about electrical safety. If at all bitmain want to flog these wares, they should get them certified by BSI (or the relevant authorities in respective jusrisdictions) which will itself speak volumes, rather than let users rely on a non electrically qualified fraudster's advice.

Dangerous stuff indeed. What is even more worrying is the question of quality control - what happened in that department? If this sort of thing can get through QC, one has to ask, what else does? QC is of utmost importance, especislly when high voltage/amperage power units are concerned, & is supposed to stop this kind of shoddy workmanship ever getting out into the wild - but here it is......

I'll pass on these things thanks, & would advise everyone else to do the same until Bitmain pull their finger out.

Pretty sure he's thinking about the mine in Thailand with a bunch of Spondoolies(not owned by them, but built out with their equipment) gear.

Did you just make that up?

Agreed, 18 gauge isn't enough & the price is too high. These reasons alone are enough not to buy one, but the workmanship, quality & history of Bitmain brand PSU's (S4) are even more reason to avoid these. Bitmain have already lost one of their own mining farms to fire, it's no surprise why looking at those pictures, you'd think they had learned their lesson.....

As far as PSU's go, you can't risk compromise: quality parts & workmanship win every time, something these don't have. It's just not worth the risk.

Guys not to defend anyone.  Bitmaintech built pretty good

 s-1's
 s-3's
 s-5's

 they don't burn up often.

And while the psu in the photos looks bad on the inside no one  else has done any photos of it unboxed then opened.

Frankly I am not interested in buying one to test it for everyone   because


it is 188 usd to my house
I do not need it.
I know I do not want 18 gauge cables.------------biggest reason is this.


I AM CURIOUS does it do 92-93.8%.
I could hook a lot of lower power gear to it.


But I am only saying  188 shipped to the USA is high price.

I rather 16 gauge cables .

GREAT BITMAIN IS NOW IN THE BUISNESS OF KILLING PEOPLE. way to go bitmain I would never buy one after looking at those pics.

If you paid VAT to dogie for items you should read this thread:  https://bitcointalk.org/index.php?topic=1018906.0

not my link just pointing something out.

Dogie I always knew you were a scammer one that works for bitmain to.

Dogie you sure you didn't build that supply for bitmain.
  

PatMan dude, bang on! Let's just look at those pics again:


These things just scream one thing: DANGER!! I can't stress enough how much miners should avoid purchasing these if they value their homes, possesions & lives.

Absolutely Shocking.

With Bitmains previous record with PSU's, I would be very wary of purchasing these potential fire hazards. However, having seen the terrible workmanship in the pics uploaded on the first page, I would now say avoid these PSU's at all costs. Stick to superior quality, proven & cheaper server PSU's off ebay.

These things could, quite literally, kill you. They should be banned worldwide.

Bitmain, what are you playing at 

  and it is now 155 + 33 = 188   usa

 which really is too high   but if some one gets it and wants to show it on power ratings please do. I am curious to see if it does 92.0% to 93.8%

you just love to say that doggie it must be most gratifying for you especially when you get yours free !

Sorry to disappoint but the bug has now been fixed Shipping charges for all!

looks that way.  it is small and lite compared to a miner.

are there no shipping charges on this?

Post corrected about the plug, thanks. Might as well add that one source for 240v C19/20 cords is http://www.stayonline.com/detail.aspx?id=38741

Bummer about the current signal. It isn't derived inside the PSU and just bought out via the high-density plug?

The stock boards don't have the current measurement anymore; that feature was too expensive to implement in mass (not many people wanted it). Also, the Bitmain PSU is C13/C14 plug and the DPS2K is C19/C20.

That actually looks pretty good to me and I'm a huge fan of the HP 1200w and the IBM 2kw PSU's. It's fun to putter around but...

Modding and soldering cables on the HP's for running 3 s3's or using the breakouts and cables from http://gekkoscience.com/products/IBM2K_board.html for a IBM 2kw PSU takes a fair bit of time each. The 2kw PSU, breakout and 12 cables total $133 vs $155 for Bitmains - pretty close there already, scale power/price and pretty much dead even.

 it takes me about 1hr total to twist the 12 PCIe 36" long 16ga cables into nice looking ones followed by twisting them into 6-pairs of cables to look pretty. Then screwing down all the wire lugs  onto the terminal block. Once that's done more twisting. This time the 6-pairs into 3 master cables running to the miners. Plus the IBM's do not have fans so gotta do that as well. But, sure looks nice

With Bitmain's we get the 8 PCIe needed to very comfortably run 2 s5's even OC'd with 4 spare cables for whatever or can run 3 fully plugged S3's. Also uses the normal C13/14 plug so easy to find cords. A minus is the cables only being 18" long - makes for interesting arrangements..
Query: Does it have local/remote control, status pinouts or can it be tied into n+1 redundant?

With the IBM 2kw and 12 cables (again, 36" and 16ga) I comfortably run 3 S5's pulling 1.8kw, no spare PCIe. It also uses the harder to find C19/20 plug. But the breakout provides local/remote control - has a switch for local, has headers for plugging in up to 2 of the needed fans and has local/remote fan speed control as well. Also has scaled current output signal (33mv/Amp) and can be wired as N+1.

That said, Bitmain's still looks good enough for me to give 2 a try. No time spent futzing around, just plug in and mine

rule of thumb if your going to run PSU's 24/7 run them at around 50% load max. this has been proven in a lab.

If you run them at max load you will get ripple voltage which is an UNCLEAN VOLTAGE with BITMAIN antminers knowing how sensitive they are. Ripple voltage is unclean period don't run them more than 80 percent load if you must. this also has been proven for many years in a lab.

Single rail PSU is the way to go. I get hardly any HW errors and I don't have to reset them every week. and that's enough proof for me.

 

I don't know if I would brag about this.   That is pretty much overkill.  And at around 80 percent is most efficient.

*I stand corrected 50 percent is a little bit better.  I can still learn I guess .  

But I still would go for at least 80 percent gold.  And would run closer to watt's used and not 1/2.  Just would take a lot for that extra few percent to pay off a EVGA 1300.

I run TWO EVGA 1300 watt G2 supernova's at roughly 50% load and they run at ambient temperature "ROOM TEMP" not even the slightest bit warm !


one S5 on each PSU.
