what is left from the lot is an unused antminer s1 and two bfl single 60 power supplies.. and it would be nice to avoid buying another psu..
would it be possible for this config to ever work (1 bfl psu in each hashing board)?
It should work. BFL Singles draw around 250W, and an over clocked S1 only needs 200W per blade. Both measured at the wall.
Note: the BFL Single PSUs are poorly made and inefficient. I know this because I had three of them. I replaced them with AX1200i platinum PSUs and got lower W at the wall. Also people have reported the BFL Single PSUs failing. If I was you, I'd use a proper ATX PSU for peace of mind.
