Ok I understand. I found some really cheap PSUs ( Tecnoware ) 500W PSU for 25€....what you guys say about that? If they are ok to use, I would use 1 on each miner.

I suggest using a good gold or platinum power supply. You don't want your power supply to killl your s3 miner..

A lot depends on quality and efficiency of the PSU. My S3's arrived today, I only had generic ATX 550W PSUs handy (pci-e wires for server PSUs didn't arrive on time), I hooked it up to generics and a single S3 unit wouldn't power off a 550W PSU. I had to split the load between two 550W PSUs. I then plugged one 550W watt PSU powering only single blade of A3 (one with WRT/config card) into socket with load and voltage reader and a single blade running off some generic chinese power supply is drawing 249W, so far cry from manufacturers figure of 360W per unit, 180W per blade. Obviously losses on 12V rail in this particular PSU must be epic, but fair bet that 750W version of PSU with such terrible design wouldn't be able to power two S3's, you could barely power up one.

Ok I have a few questions I would like to ask about S3s.

What is good ( in terms of safety and watts / GHs ) clock speed to overclock my S3 miners?

And what PSU would you suggest me to run 2 miners at that clock speed?

I have already posted my question in one of S3 threads, but my post got behind so fast, so I decided to make a new thread.

Thanks.
