The psu I have is a Corsair CXM Series CX750. On the +12v rail it is 62 amp 744 watts. I'm just wondering if it will run 5 or 6 of the boards until my new supply comes in, which according to ebay won't be for about a week and a half. I guess maybe I should have asked what the wattage of each board is?

Check the data on the PSU.
Make sure the 12v rails have enough 12v capacity.
Just because a PSU says 750W does not mean the 12v rails will provide a full 750W.
The newer ones do list them as such but most older ones is a "total of all" the various voltages...
Check out Server PSUs on ebay for replacements rather than desktop PSUs.

If you have a bunch of 12V miners running on PSUs PM me and I will get you some info.

Can anyone tell me if a 750w psu would be able to run an s2 with just 5 or 6 hashing boards? The reason I ask is because I recently bought one off ebay. It ran fine for ~ a week. Yesterday the psu caught fire, so I took it out and am now waiting on a new one. I have a 750 running an s3 and I'm just trying to maximize my potential. Any input is appreciated.

Most hardware giants don't deal with tiny screws still searching.  I guess I will put a ticket in with the big B.

Anyone handy with fixing these. I just listed my 2Ths S4 on ebay starting at $49 (no reserve). Does need some sort of repair.

They are about 5C lower but I noticed that the temp sensor is located to the end of the original exhaust side so the readings might not be accurate.

cool which range of temperatures are you running?

If any of you would like your S2 to be more quiet then turn the exhaust fans the other way so they become intake fans and remove the case.

The miner is pretty much silent now compared to before where it sounded like a jet.

Just take one to your local hardware store and match the thread and length.

What size screws are used on the S2 case?  Have a few needing replacement.

Ya, that's why we keep bugging them.  A little to late for this info I'm afraid.  Come on step it up please.

Aww.

All my S2s are shut down now, they suck more than they make...

Thanks BitmainWarranty working at full flow...

NO new news.....

Nothing... Niente...Nihil...Nein... NADA,無, 没有...

Hey BitmainWarranty, any news coming soon on the upgrade kit?

Possibly removing the https:// from the URL?

I would say, power the S2 off and unplug it from the wall.

Disconnect the PSU. 

Weare a protective non-conductive gloves

Then reseat each hashing PCB and the center control PCB.
 
Power it back on.

If that doesn't work, refresh the firmware (DO NOT CARRY ON THE PREVIOUS SETTING)

Hi all im the new guy on the block! lol
well i need a helping hand please..my s2 is no mining at all
i have a laptop running linux peppermint sharing wifi over lan to the s2
the s2 look connected to internet... im able to ping  bitmaintech.com

any one willing to help???

thank you all

Just picked one of these babies up.

Compared to an S3 how loud is it approx?

Yikes.. just when they anounce the S2 Upgrade kit then their website went dead

Well Lunar New Year is over... are they going to release the S2 Upgrade kit??

Fingers Cross!!!
