I've read on multiple websites that the power consumption for the 6670 1GB, MAX TDP is around 65w. So would I need to upgrade the power supply or just remain with the same one. If more information is needed about the PSU in my system please leave a reply and I will post it on here.
Dear Halo Don,
Considering the site you showed me i have seen it before. and i'm sceptical if it's a good site or not. But your 250watt SHOULD be fine for the card,cpu and specs you listed.
here below is the 6670 at MAX power usage. meaning it will draw no more then this when at full load.
In any case if you do notice your computer crashing,not starting right,shutting off then a cheap 300-400watt psu is maybe 30 dollars at most and you would be set.
the link you sent me a guy also commented and said it runs fine with a 300watt. im sure 250watt should be enough as well.
I wouldn't say you actually "need" a new PSU for it. But I do warn that such a configuration could begin to stress that PSU should the CPU and GPU both have to operate at full load for extended periods.
Also, with better GPU's (5750/5770 & 6750/6770) within a $10 to $20 stone's throw of that 6670, it doesn't offer nearly the same performance/dollar value as a 5770. Especially considering how much better the performance of a 5770 would be.
Basically, $50 more bucks (up-front) can get you a much better card and a high-quality PSU. If you go for the card and Corsair PSU, after-rebate cost is only $115, which is only $15 more than where you started with just the 6670 card.
