Question Antec NE500M vs Corsair CX450

[ironman33155]

My old PSU died recently and I was thinking of buying one of these. I would love to purchase Seasonic but its expensive because it ships from US. I planned to buy the VS450 but the reviews changed my mind. The CX450 is twice as expensive as the VS450 and almost the same price as the NE550M. I've calculated the power requirements and it says I need about 422W. So I guess 450W should not be less. The Antec is modular so that should help me with my lousy wire management skills.

Specs:
CPU: Intel I5 4440
Motherboard: Gigabyte GA-H81M-S-LGA 1150
Ram: Hyperx Fury 8GB
SSD/HDD: WD Black 1 GB + Seagate 1 Gb (Don't Know the exact one)
GPU: Zotac GTX 960 4Gb
PSU: Corsais CX430 (5-6 Years old)
Chassis: Intex Case (A cheap case from an Indian Brand)
OS: Windows 7 + Windows 10 Dual Boot

The NeoEco550M ...Is more than enough power and that system would never draw near 422w.
