I have a question about ANTMiner S3
Watt what is needed to run 4x S3?
if 1 S3 360Watt, so 4 S3 = 1440
whether the LEPA 1700 Watt power supply able to handle this ??
please give your review
thank you

The LEPA P1700 Modular is a very powerful power supply having 6 +12V rails.
Two of the +12V rails are rated for 20A each and so with will give 12V*20A = 240W each rail.
The other four +12V rails individually rated for 30A which means 30*12=360W each.
A single S3 blade need 180+ Watts atleast. With this PSU we can connect the 20A 2 rails to two blade maximum.
Then the next 360W rail may not be enough for 2 blades and so we need to connect the 360W to one blade each.
Inshort 1 S3 can be powered with 2 rails and another 2 S3s can be connected with the other 4 rails.
Which means we can connect a maximum of 3 S3-es in that Power supply.
For three S3 there are a lot of other options and this one is too expensive.
I think that PSU is not targetted to asic miners.

How would you do this, i have one (LEPA G1600, looks the same as the 1700)

The two 20A rails are for the moterboard and cpu.
Only four rails are pci-e, are there converters or something?
