  2. Best answer
    I would get the Corsair CX430 before a CM unit. It would run the system fine.

    No the included 420watt is not sufficient it is an old design lacking power on the +12 volts!
  4. That 420w unit is crap coming with it

    heres the Corsair 430 Rolli mentioned

  5. It is not enough, time to change your psu at least 600w
  6. 600w for a rebranded 5770?
  7. i think the 600w would be overkill for this system and not to mention the electricity bill thats gonna come with it (we have very high electricity rates in our country).

    does this sound any better ?

    It is a little better, it is newer design but has not gotten good reviews. The size of the PSU is not going to affect your bill it only pulls from the wall the same amount as your components use. That is 500 or 600 watt with the same efficiency would have the same effect on your power bill.
  9. I personally would go with the Corsair CX430 out of those choices.
  10. Corsair first, Antec second, ThermalTake and CoolerMaster never.
  11. jsc do u agree with rolli59 ?
  12. corsair 430
  13. since the majority says the corsair one is the best then i think i should go for it only.

    ty rolli59, gnomio, jsc.... u guys have been a great help thank u

  15. It's very easy to do the calculations to properly determine exactly what PSU power in watts and 12v rail current is required for your current or future PC build. No guessing is required. You can also determine what PSUs are quality PSUs as not all model from suppliers like Corsair, Antec, Rosewill, etc. are quality PSUs.
