Lowest Ripple suppression on 12v single rail

I have an old Enermax Revolution 85+ 950w in my gaming rig. This was before I knew anything about power supplies. Today I take a power supply a little more serious when choosing one. I like for a good balance of stability, ripple suppression, and efficiency in the proper range, etc. The other day I was reading a thread I was following and a guy swapped out his PSU and his overclock became stable at less voltage at the same overclock speed. This got the rusty gears turning and I was just curious what 12v single rail PSU in the 650-900w range has the lowest ripple suppression?
