Actually Corsair CX or TX series power supplies are good but are now very expensive than they used to be.
You should also visit PG market place for psus because if you are able to find a good psu in new condition, it would be great.
Regarding current options, Thermaltake TR2 series is also good. if you are able to find it, its good, gold rate and cheaper than corsair.
or if you are able to find ANTEC power supplies those are also good.
