One last check on PSU before I order parts

I have, for the most part, confirmed all of my specs for this build except for the PSU, so I would like to get some input one last time before I go through with ordering everything for my first gaming rig build. My main specs:
Sapphire Radeon HD 7850 1GB
Intel Core i3-3220 3.3Ghz
ASRock H77M Micro ATX LGA1155 Motherboard
Rosewill Challenger U3 case. Comes with 3 fans

My budget for PSU can not exceed $70 before rebates. I am looking for quality and enough Amps to support my system without harming it.

According to http://extreme.outervision.com/PSUEngine, my video card's max watt is about 184. Taking that, and using this guide for amps: http://www.tomshardware.com/forum/314712-28-please-read...
I came up with around 15 amps for the card, and doing the rest of the suggestions, I get 35 amps.

Given all these factors, these are the PSUs I've picked and am deciding on:

XFX 550W PRO550W Core Edition $65 @ NCIX (After rebate: 55$)
Non-modular,single rail, +12v 40A, 5 year warranty

Rosewill Hive 550W 80 PLUS Bronze $65 @ Amazon
Modular, +12v 38A single rail, 3 year warranty
http://www.amazon.com/dp/B005ILWY9G/?tag=pcpapi-20

Rosewill CAPSTONE Series 450W $60 @ Amazon (Can go Semi-modular for $10 more)
Non-modular version, Single rail, +12V 37A
http://www.amazon.com/dp/B006BCKDGW/?tag=pcpapi-20

This is my last thread before I order all of my parts for a budget gaming PC.
I would like to know if these are good quality PSUs and which one would be the best buy; and whether or not modular is worth it over a higher watt PSU. The XFX appears to be the best as far as amperage, but I do not know the quality of them.(Although it is JohnnyGuru recommended.)
And would all these support my build? I don't plan to overclock or use two video cards. The only thing I might possibly do is install a SSD sometime in the future. This PSU may also be used in future builds if necessary.

id go with the 550watt ps made by xfx, well actually made by seasonic but rebadge as xfx, top quality, and good warranty and service.

So that XFX one is made by Seasonic? I guess that is my best choice then, especially for the price. My only con with it would be that it's not modular, but is the modular aspect of the others really worth it as far as airflow is concerned? I've never built before so I don't know much about cable management aside from computer build videos.

yes,

thats right, not realy changes the airflow a bit, but if u hide the cables away somewhere isnt really an issue :) , id suggest a modular ps but will cost u a nice chunk more.
