Building a gaming rig, but need help with PSU


Like the title says, I'm building a new gaming rig. Now, I've already settled on most of the components except the PSU. So I need some help here..

The PSU I wanted to get is the Seasonic SS-520GM but what confuses me a lot is that a manufacturer like Seasonic would exclude OCP, UVP and OTP from their PSU as seen on the bottom of this page .

So, what should I do? In the country I live in, the PSU choice is very very poor, so this is basically the best you can find. Most of the PSUs here are old models from Chieftec and Cooler Master which are not any good.

Just for reference, the other components will be:

CPU: Intel i5-3570k
MB: Gigabyte GA-Z77X-UD3H
GFX: AMD Powercolor HD 7870
RAM: Mushkin Enhanced Redline 2x4GB 1866 MHz
SSD: Mushkin Enhanced Chronos 120GB
HDD: Western Digital 1TB

  1. You should be fine with a quality 450w-550w PSU

    As I said, the PSU choice here isn't good.. So just settle with this Seasonic unit?
  3. 2 PCI-E slots, I suggest a 650-700 just incase you want to SLI in the future.

    Corsair or Seasonic

    CORSAIR Enthusiast Series TX650 or 750, imo.
