Given the unbranded PSU and the fact that you're likely very close to limits using that card, I'd be hesitant to say things would be rosy if you put it in your system. Having said that I think under normal loads it would do just fine, you might get some issues when taxing it though. Quality of the PSU is an important variable in all this.
But "recommended" outputs are generally way overstated, so...
I have a AMD ATHLON x3 450 3.2 ghz(i'm not planinng to overclock it) ram-4 gb ddr3 1333 mhz single slot, hdd 500 gb 7200 RPM 3.5, motherboard ASUS M4A78LT M LE. I'll check the psu now and i'll reply it to you guys.
Thanks for the answers do far!
Card manufacturers frequently overstate PSU requirements. If you read back through this thread you'll see that your card draws around 130W under load, so this leaves you with quite a bit of breathing room, especially if you don't plan to overclock and your system is otherwise stock. Most of this depends on the quality of your PSU, which from what I can tell from other posts on this thread is adequate. Assuming you have a quality PSU, I'd feel comfortable saying you are good to go with the 6850, assuming all the assumptions I've state here are true.
Thats what I wanted to hear.I'm in doubt becouse few people told me that my psu wont be good enough, exactly that my 6850 wont be getting enough power.So, from you two guys i can be sure that everything will work propertly. Anyone else?
