Can a AMD Radeon 6850 run on a 400 Watt PSU?

Hello Friends, I'm buying a new graphics card for my PC which is AMD radeon 6850 1GB GDDR5. My monitor resolution is 1024*768 , so it runs all games pretty well at that resolution.I have a 400 watt PSU. I wanted to ask whether my current PSU will suffice for me just now? (I'm not a hardcore gamer and not upgrading my specs for Crossfire/SLI).

My computer specs:

AMD Phenom 9650 quad core processor
4gb ddr2 ram
Samsung 500 gb hard drive
Monitor resolution: 1024*768
ASUS M2N68-AM PLUS motherboard

I had earlier posted on these forums and i got very good replies about buying AMD radeon 7750. But it is very new card and will take at least 4-5 months to settle at all the local dealers in my country which, is ,India.so, i will have to buy the graphics card i mentioned above which is available easily now at all the local dealers in my country.

***Please dont reply about upgrading my CPU or other parts.I am not upgrading them just now as i'm a budget buyer and just want to upgrade my graphics card for now.****

I know mine is not a gaming rig. but please help me.!!

  2. Short answer: yes, but what brand/model PSU do you use?

    http://www.anandtech.com/bench/Product/291
    total system load (furmark): 274W
  3. Go for a better PSU. HD6850 wants 25A on +12v rail. It will run on a 400w if the psu is a good model. If it is not a trusted brand, buy a 500W to be on the safe side..
  4. My PSU is of local quality and can anyone please tell me if this graphic card will be compatible with my motherboard?
