Here is my Specs.
Sapphirre HD 7770
asus H61 - MLX
2 internal HDD
Im looking for a power supply that can power up those in full load and for my future upgrades like i5 3570k, and gtx 670 or Radeon HD 7970. But i'm quite confused what to choose from this power supplies because i searched about them and they got good reviews. Also this is based from my budget which is around $50 and the availability in the stores. I prefer cheaper but reliable that will last for at least 3-5 yrs. I arranged them based on their prices. lowest to highest.
The best one I think is the corsair however it is only the builders series. Seasonics cheaper power supplies tend to be quite good also, however I don't know about this specific model. Either of those psu's should be fine for your pc and should last you
