Hi guys,

I'm taking my first steps in building a gaming PC.
My CPU is Intel Core 2 Dou with 2GB of RAM.
I'm looking forward to the AMD HD 6670 GDDR5.

Is it a good card for my system?
Since I wanna play COD 7, Crysis 2, Kingdoms of Amalur and so.

Also I wanna ask about the PSU for the VGA above.
I have Cooler Master RS 460 - PCAR - here: http://www.coolermaster.com/product.php?product_id=3686
Is this PSU capable?

I've read about the PSU requirement for HD 6670, it says that I need a 400W PSU.
Mine is 460W but devided into 165W + 312W +... ( u can see in the link )
So I don't quite understand what did they refer to when they say a 400W PSU.

Thank you all. :love:

technically your current PSU would work ok, however its always good to get a good PSU with an 80+ certification and it never hurts to aim an extra 150W or so head room. I know new egg has some really good deal on a corsair 500w right now. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thank you.
I'm glad to know that.

BTW, could you please explain to me about how my 400W is divided in to 165W +312W and so?
And what does AMD means when they say a 400W PSU?
I mean what if my 460W PSU is divided with 230W-230W, not 165- 312?

Well the 6670 works on a 300W PSU (From my personal experience) and my friend uses one on a 250W PSU so your Cooler Master RS 460W (Above recommended) will definitely work.

The part you were confused about is where is says +3.3V +5V = 165W and 12V = 312W

All you need to know about that is the video card and processor (two most power demanding components) Run off the 12V rail not the 3.3V or 5V. Your PSU has 312W on the 12V so it is definitely enough.

HD 6670 uses 10W on idle and 58W at max load and core 2 duo uses 17W on idle and 63W at max load.

AMD recommends a 400W PSU because they don't know how power hungry your system is or if the PSU actually supply's the listed watts so they recommend a 400W just to be safe.
