i am buying a new pc for gaming and have trouble with finding the total wattage my system would require to run. my specs...

core i5 2400
intel DH61WW mobo
ATI radeon 6770
4GB DDR3 corsair value select
Samsung DVDRW 22x DL SATA

someone told me that a 420 watt psu would be enuf for it but i need some reasurrance if it will be ok to use this...

P.S. : i did read the guide on the forum but being a total noob i didnt understand how that worked so i am posting this.

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!

It is not enough, time to change your psu at least 600w

600w for a rebranded 5770?

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.

I personally would go with the Corsair CX430 out of those choices.

Corsair first, Antec second, ThermalTake and CoolerMaster never.

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.
