Hi,

I bought a block erupter cube second hand from a guy who said it worked great.  I have a spare 750W power supply but it has only 1 6 pin PCI-e so I bought an adapter to convert one of the sata connections to the PCI-e 6  pin.  Anyway, I plugged it all in, shorted the ps so it stays on full time, and....nothing.  One green light goes on then it looks like the other lights for a second and then the cube powers off, shorting my PS with it.

I can get it to not short the PS by plugging in no more than 3 boards.  Never does the ethernet port ever show a light (with or without a cable) and I honestly don't know enough about these things to figure out what may be wrong.

I was told the board has a lifetime warranty but how do I know if it is my cube or some other problem, perhaps with my power supply?

Tips or help are welcome.

Chris
