The Corsair CX series isn't great, but they're slightly better than the Kingwin. The biggest issue is that they're "soft" overrated, meaning that the CX500 can provide 500W theoretically, but in practical usage it's more like 450W***. Also the CX series is inferior to the CXv2 series (such as CX500v2) which is essentially the same but with a few upgraded components and higher efficiency.
It's not a bad unit, but there are better and depending on what you paid it might have been a poor choice.
***Compare this to hard overrating that companies like CoolerMaster do, where their 475W PSU is neither practically nor theoretically capable of providing 475W in any situation and in fact blows up at around 380-400W. Soft overrating isn't as abhorrent as hard overrating, but it's still considered poor form.
