Right PSU for my setup

[donatdodat]

Here is my current setup:
CPU: AMD FX 6300
MOBO: Gigabyte GA-990FXA-UD3 ATX AM3+ Motherboard
RAM: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory
storage:Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video card:Sapphire Radeon R9 270X 2GB Video Card

I am a little short on my budget and im just wondering if i should go with 520w or 620w?
Options would be Seasonic M1211 520w (modular) or Seasonic S1211 620w(non modular). I really like modular for cable management but if my 520w is not sufficient then i have no choice but to go non modular 620w since the price difference is around $17 for a modular 620w.
This is my gaming build and i have no plans for crossfire/sli in the near future. i might be OCing a bit but not too high. Thanks

520W will be sufficient for your setup. Modular PSU helps in cable management. No issue there.

The 520 will be sufficient but personally I would probably run with the 620 due to overclocking headroom. If you case doesn't allow much cable management then the 520 will be a good choice.
