Depends on your location. In the US the 550w Xfx or the 520w Seasonic are usually the best budger units. If you dont mind a mail in rebate you can usually get a great deal on a 750w Evga B2.
Thanks, those are pretty good and affordable units, I'll keep them on mind.
However, I calculated my power consumption with an online calculator and it says that with my current build my load wattage is 310W and recommended wattage is 360W. Shouldn't my current PSU be enough?
Although, I might have to buy a new PSU as 2x6-pin => 8-pin adapters are pretty much non-existent where I live.
