CX430 is good. But definitely not up to the mark compared to the older Corsair PSU's. Somehow Corsair have somewhat gone off the boil in recent times. Their older VX,TX,HX and only one CX400 were simply amazing. But these days they have some new CX and GS series which are a bit behind.
I've got no problem using a lower end psu if need be, but you can get the EA500D for $4 more, if that's gonna break the budget, save for another week or steal the kids lunch money. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Well worth the $4.
Buying a decent quality psu is like a game, watch for the deal when it comes around ( usually quite often ) then jump on it.
The CX430 only has one 6pin PCIe connector and only three 4pin peripheral connectors. I doubt you would be able to power four fans with the remaining peripheral connector after using the other two to connect to the peripheral to PCIe adapters, unless, maybe all of the fans have peripheral connectors and are quite close to each other or their cables are all long enough to reach the connector on the PSU. And like malmental said, I don't think I'd want it even then.
The XFX linked does have two PCIe connectors as well as having a lot more other connectors besides.
