I finally got one of these SP20's ordered up! I hope it lives up to Philip's praises

I was hoping that I had a single PSU to run it, but now I am not so sure? I have several LEPA 1600's sitting around and some Corsair 1200AXi's. I suppose maybe dual CX750's would do the trick.
I got my SP20 last month and have been running it on 2 CX750M's. Let me know if you want me to try any settings with it before deciding which power supply you are going to go with.
