I have thermaltake smart 850, single rail:
Output Specification

AC INPUT Input Voltage: 100V-240V
 Input Current: 12A
 Frequency: 47Hz-63Hz
DC OUTPUT +3.3V +5V +12V -12V +5VSB
Max Output Current 25A 25A 70A 0.8A 3.0A
Max Output Power 130W 840W 9.6W 15W
Continuous Power 850W

better or worse? I am thinking that the goal is lowest wattage with highest amperage? forgive my stupidity, not an electrician, slept through shop and physics classes and way too many years ago anyways

I assume the +5v 130W is what philipma1957 refers to  saying ' most are 125W '

 yeah  the thermaltake smart 850 has 2 ratings for the secondaries 5 volts at 25 amps  and 130 watts.

only one of those are correct.  since they represent different values.  5 at 25 amps = 125 watts   and that does not = 130 watts.

 newer PSU's  are 12 volt only   and then 2 dc to dc converter transistor/chips   one from 12 v to 3.3 v  and one from 12 v to 5 v.

 the dc converter is more often then not rated at 25 amps.   

 safe 24/7/365  is 80%  or about 40 sticks.

thanks philipma1957

wow, I am such a pack rat, just found another one LBX-350 atx 1.1 35A 5V rail!

Will you be updating this same thread when new stock arrives?

[CrazyGuy]

Will you be updating this same thread when new stock arrives?

Yes, I expect more next week.

[stevenf]

Hmm very interesting!

What is the price for the hub alone with international shipping to the Netherlands?

[philipma1957]

Will you be updating this same thread when new stock arrives?

Yes, I expect more next week.

I HAVE A test bed setup.  your package is due to me on monday.


I will hookup 40 sticks to a 5 hub setup check the power use with a kill-a-watt.

I will then hook the same 40 sticks up to the 49 port hub check watts use with about 7 psu's .

 

I was doing some projections on this as a money earning space heater.
I can fit this out of site behind my flat screen tv in my basement den.  Always too cold in the winter (except last year due to gpu btc mining).
 I  will set up 40 sticks on a low power pc with this hub. I may mine 13.33 at 200 watts. That would be about 1000 btu an hour 24k btu a day or 744,000 btu a month. That is 7.5 therms of gas heat a month or around 10 bucks of free heat.

   I may be able to mine at a difficulty of 2 bill and not be losing money due to the free heat which would work until April or May.

[clarkey2013]

do a group buy on the hub  uk shipping also 

[kapior]

Do You shipping to EU? What is the price?

 At canary  that is a nice find.

I found 2 others  for 20 bucks each, when I test the hub I will post if they work. I hate to tip everyone to a bad piece of gear.  If I were to bet on your psu working or the ones I found I would bet yours works not mine. the seller sells a lot of surplus my success rate has been about 75% with his gear. Even if these 20 dollar ones work I have so many psu's.

 I wonder if these use too much juice at the wall.

I received my second batch of USB hubs today. I will update the thread when stock is depleted.

All of today's purchases will be packaged tonight and shipped tomorrow morning. Also, I've arranged for an individual to handle shipments during the day. Starting tomorrow, all orders placed before 11:00 am CST should be shipped same day.

[bitterdog]

Received my package today... running like a champ... time to sell it off .... lol

Thanks

got mine today . having a few issues but 34 ports work fine.  right now I am using a 225 usd sea sonic  platinum 1000 watt psu. running 34 ports  . I am pulling 117 watts at the wall . not surprised as 34 x 2.5 =  85 watts divide by 70 percent you get 121 watts.   so my efficiency is in the 70's

near as I can figure my hub has 2 bad banks row 8- 14 and row 15-21 are powered but do not detect the hubs. 1 lone port does not work in bank 42-49

hard to tell why.  one thing for sure  it is a nice size for am sticks .  you can use just 2 fans to cool it.

I will test more psu's as I would like to find the best one. for running 34 sticks.

it also may be that running this hub on a different pc will allow more then 34 sticks

Is it powering the units and your controller is just not recognizing them? Try isolating the two banks in question and unplugging all other units.

I got it to work on a different pc.  right now I am running 44 sticks using a  Nzxt psu a 650 watt model rated for 5 v

25 amp.  I am also using the four pin 12 volt cable to run a pair of 12 volt fans.  total power at the wall is 159 watts for 44 sticks and 2 fans.  seems to be a decent piece of gear.

but it may vary from pc to pc.  I am going to run more tests and post later today and tommorow.    On wed. thurs  I get 2 surplus 20 dollar psu's.. if they work I will give links  to buy them.
