OCZ is average at best. They don't make anything. They use PSU manufacturers like Channel Well, Impervio, and FSP.
Not on my list.
If you have some good but as yet unexplained reason to believe the XFX 450 does not have enough power, get a higher wattage unit from:
Antec, certain models
Corsair, certain models
You are hampered by your budget.
You are better off with the XFX 450 than a random 600 watt unit built by who knows who.
As with all your other posts, you are better off not worrying about this stuff until you are a month away from buying---which will be next year some time, according to you.
Why do you think you need 400 to 430 watts to run "your system"---whatever that may be?
