I'm running a 850w and a 950w Corsair on 2 systems each running 11 hard drives.

Steve, what for do you need the ratings? if we know better what you want, we can offer tailored answers

I went with an HX series 1010w unit.
Thanks for all the effort to assist me!
Thanks for all the effort to assist me!
SteveDico I'd like to add, where possible get a certification that the PSU does what it says.
It has been tested to perform without any fluctuations guaranteed.
That is why I always get Antec/ 7 year warranty and certified.

The question was about finding a quality power supply.
Tailoreddigital noted that Corsair was an excellent choice in his initial comment [ https:#a40222835 ]; and I expanded on that by noting that their lower-end units were significantly less robust and suggested he stay with an AX or HX unit [ https:#a40223411 ].
The author subsequently noted that "... I went with an HX series 1010w unit. " [ https:#a40234091 ]
Based on that, it's clear he listed to the advice in the first two posts -- I'd suggest a split between https:#a40222835 and https:#a40223411

FYI,
I haven't had any issues with the CX series.
If allowed,
Gary what kind of issues come up (so i know what to watch for)?

I've seen several instances where a system wouldn't boot with a CX series unit, but works fine with a higher quality unit. This is almost certainly due to better power regulation (both load regulation and line regulation); less ripple; better transient response; lower inrush current when powered up; and better overvoltage/overcurrent protection.
In most cases the quality difference doesn't matter; but with the very low sleep state loads of Haswell or later generation Intel CPU's the lower quality units can definitely have issues.
The simple fact is there are design tradeoffs when building a low-cost power supply that absolutely impact the quality of the power that the unit provides. I simply don't use the low-end units from ANY manufacturer.
One way to tell how well a unit is designed is to look at the warranty. While this is largely a marketing decision, the manufacturers DO provide notably better warranty coverage for their higher quality units. e.g. Corsair provides a 2-3 year warranty on the CX series units; but typically 7 to 10 years on their higher quality lines. Same is true for other major makers.
