I received my units today.  One had screws rolling around and the other had screws loose.  Neither had the vertical cards in the slots properly.  Based on other threads, I knew this might be an issue so I took them apart and fixed these issues before even starting.

As far as PSU's, I tried using both an Antec Earth Watts 680 W and an EVGA 600 B with the paper clip trick and they fired up initially but then went off line in about 5-8 seconds.

Apparently these PSUs will turn off if certain loads don't exist.

I tried to hookup a simple case fan to both PSUs via a moldex converter to try and fool the PSU into powering on but no luck.

I hooked the EVGA PSU up to an older computer (that doesn't need the PCI-X power cables).  With the computer powered up, I have been able to get the unit to stay powered up.  No X's show which is good.  However, I am only getting 3-5 GH/s while mining. 

I tested both the mining_proxy_1.2.0 on windows and bfgminer's proxy on linux but the hash rate remains un-changed.

Is anyone else seeing low hash rates like this? Have any idea how to fix them?

What PSU would be good enough to run 2 units via the paper clip trick (i.e. no need to use a computer to simulate load)?

Thanks
