Please help with my new RIG I need a PSU!

[patrs4]

Hi guys! I need your help because i can't choose the right PSU. Please, recommend what you think would be better other than the listed!

The cooler master power supply calculator says the system will need atleast 402W.
The listed 3 PSU's have 6 SATA cables which is more than enough for my 2 HDDs. 80 silver or 80 gold would be great, maybe 80 bronze! Would 600W PSU an over kill because of efficiency?

I also need 2x6pin connector.

I don't need a modular or any fancy PSU just a standard one with atleast 4-6 SATA and 2 6pin connectors. I want to be safe so my components won't get damaged!!!
What i've looked for is:
Cooler Master Elite Power 600W RS600-ACABM-WB (2x6pin) 48$
Cooler Master B500 ver.2 500W (2x6pin) 46$
Cooler Master B2 500W - RS500-ACABB1-EU (2x6+2pin) 48$
I'm on my budget. so the maximum i could spend on it is about 50-55$.
My rig:
FX-6300
2 HDDs (Sata 3.0 1TB and a 500GB Sata 3.0)
Sapphire Toxic R9 270X
1 optical drive (currently not plugged in because i don't use it.)
I'd really appreciate your support! I've heard you are a great community, and happy new year!

This is good as a basic one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438016&cm_re=500_evga-_-17-438-016-_-Product

 

And this is the one that I have and would recommend: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438017&cm_re=750_evga-_-17-438-017-_-Product

 

EVGA is my preffered PSU brand.

Or I have a corsair 600w modular PSU haven't had any problems with it and you could save a couple bucks and just get the non modular one but I'd definitely get a 600w more room for expandability in the future.
