Hd4850 and ENERMAX EG425P-VE 420W

[corky]

Hey All,
First I'm sorry for my bad English !!
I'm wondering if I could upgrade to ATI hd4850 without upgrading my power supply ?
I'm using ENERMAX Noisetaker II EG425P-VE 420W.

And I need advise what should I buy Sapphire OR Gigabyte?

Thx

Your psu has 29amps combined on the +12volt rail which should be enough. I have good experience with Sapphire.

you should be ok with that power supply. i've heard of people running 4850's with a 380W power supply. and either brand is a great choice.
