Can my system handle a HD 6850 O.C version???

[panokan]

Hi , i want to upgrade my graphic card


so my main quesion is :


Can my system power up a

HD 6850 graphic card without problems?
The graphic card that i am interested in is a MSI R6850 CYCLONE 1GD5 PE/OC 1GB ( i know its pci-e v2.0 and i have v1, i
will not "enjoy " all the power of the card but i will be 10000 times better than 8400 gs)

My system is :
cpu: Intel Core 2 Quad Q6600 Kentsfield
ddr 3 : 8 gb 1066 Mhz
one hard drive 160gb ( sata 2)
gpu:8400 ( i know its a rubish )
psu: TAGAN TG480-U01 480W


so my powers suply specs are:
(i would love to upload an image if thats easier for you but i dont know.. how..sorry )


+3.3v=28 A +12v=28A -5v=0.8A
+5V=48A -12V=1.0A +5vsb=2.5A

Also about my thinking : I have read that a HD 6850 in its peak performance needs about 278 W???

My cpu needs 105W at maximum load
my hard drive is about 7 wats i think.... and i have only 2 case fans of total power 8 wats of them....

So if we sum them its a total of 398 watts and my psu cann offer 480... So i am right??? the numbers say that i am correct?? I am asking because amd says that it needs a 500W psu at least...


thanks for reading my big thread , Thanks in advance again

i think that your thought is right, probably your psu can handle HD 6850 only if you dont put extra devices in the future...

i was thinking the same but i was not sure , thanks for the help

I can tell you from recent and personal experience, that a pci-e 1 slot will not slow your card down much at all. Maybe 5%. Even with the dawn of pci-e 3, cards aren't fully saturating pci-e 2. I gained zero performace increase on my HD6950 when I put it in a new mobo with pci-e 2.

Overclocking your CPU or graphics card, even just slightly, may send your power requirements over the edge. It may work, but you are walking the line.

Basically you are right. And AMD overstates the system requirement to play safe. If you want a more accurate calculation of your specific's system power requirement, use this: http://extreme.outervision.com/PSUEngine

Thanks all for your responses thanks again Thanks randomKid the site helped a lot

not with that psu, it will likely explode, especially if it is a few years old. cheap psu's use cheap capacitors that leak and degrade psu performance over time. Tagan PSU's are cheap. also they do not produce their rated power from the factory. Also you have a fair cpu bottleneck. Stick to a 6770, you wont notice the difference with that cpu, and they use less power than the 6850.

New PSU then try your hand at overclocking your c2q to reduce your bottleneck.

thanks all for your answers so i am going to have same performance with the 6770 since my cpu is old?? ok nice much better Less money for the card Thanks for the suggestion
