Block Erupter V2 - Blade PSU Troubleshooting Problems

[LarryFossil]

Hello all, I have recently received 2 version2+ blades that require 120watts @ 10amps / blade. (Already overclocked and set at 12V) I have attached some images to explain the PSU. I have tried numerous hardware configurations to get the blade working, but every time I plug in the ASIC the PSU / Fans / etc... turn off. I tried using https://bitcointalk.org/index.php?topic=205369.0 & talking on a variety IRC channels. Is my PSU not capable of supplying the needed voltage / wattage / amps to the specified ASIC board? If so, what am I doing wrong?

Here are the specs: http://www.amazon.com/Thermaltake-PurePower-W0118RU-ATX12V-Supply/dp/B000P9VGMW

(I can supply more pictures if needed)

Note: I also followed the guide I shared in beginning of post. I tried using the molex splitter and other 12v outputs.

Much help is appreciated. Thanks in advance. Larry =)

Ps. If I could get some help with this subject, I will create a better tutorial than Dogie did. I just need to get everything working first.

Update 2: I switched around the polarity & now everything seems to have power, but  I still have no blinking lights for IP (ASIC device) activity. It is plugged into slot 3 & slot 1 is connected to the computer through a LAN line. I have added some pictures to give you a good idea where I am at with getting this blade to work. Thanks!

Trial & Error:

• Reset the ASIC device by touching the two pins closets to left of Ethernet port.
• Resetting the entire PSU
• Made sure my ip ranges are in range for .254 on router
• Currently showing ~10.5-11V with two 120mm fans connected.
• Currently displaying ~11-11.6V with 0 fans connected.
• Tested various points on the ASIC board to see if it has voltage. (Which it does) Just no blinking lights or IP activity

This is Power Supply  for Pc and it want power load of all lines (3,3; 5;12v) .
Measure 5 and 12 v (3,3 and other - not important) and if it have differences above 5-10% then load this lines by resistors to put volume down, to put volume up -5 v for example load 12v by resistor.

I am sorry, can you explain in simpler terms? There are a lot of typo's & I don't know what you mean by measuring 5v and 12v on the PSU. I know the PSU has two 12v rails @ 12A (14A Peak) which should be sufficient in powering the blade. Thanks for the help =)

Unfortunately, I do not have any resistors to use and test.

Update 3:

I switched around my + & - and put them in series with the ASIC chip. I turn on PSU; Fan starts up then quits & the PSU shuts off. What could be my problem? I am using a 12V rail that is meant for 12A and I only need 1.2Watts / 10Amps per blade.

Problem:
Led light behind the ethernet port starts blinking when I initially power the board, but it shuts off.
PSU works when not connected to ASIC board.

Possibilities:
Bad PSU
Pulling to many amps from ASIC board
PSU not supplying advertised voltage

Other:
Fuse is working (tested em with diode checker)
Fans come on when not plugged into ASIC (using other 12V Rail to power the fans)
Only reading about 11.5-11.3V on multimeter when no fans are plugged in.
No smoking of the equipment as of yet =P
