Are you planning on purchasing more in the future? Do you want a single PSU to power more than one S1, or do you want individual PSUs for each?
If you're just going to have the one S1, then the CX600 is plenty powerful enough. If you're going to run 2 off the same PSU, I use the HX1050. Others have had success using as little as a CX750 to power both, but that's a bit too risky for my taste. Want to power 3 off a single PSU? You could probably get away with the AX1200i, or the EVGA G2 1300. Or you could do as some have done and use 2 CX750s to power the 3.

yeah if you want 3 ants the evga 1300 will run them there is a good deal on it here.
