With your specs, PSUCalculator says your system needs at least 312W @load with 6850.
(That's considering the CPU OC)
i don't know why i got 292w at peak load..

Radeon HD 5850
The card requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the +12 volts rails.
according to ATI the 5850 has a TDP of 151 Watts.

System in IDLE = 168 Watts
System with GPU in FULL Stress = 348 Watts

Radeon HD 6850 - On your average system the card requires you to have a 450 Watt power supply unit.

Measured power consumption - 6850
Advertised TDP = 127W
System in IDLE = 176W
System Wattage with GPU in FULL Stress = 278W Difference (GPU load) = 102 W
Add average IDLE wattage ~ 19W
Subjective obtained GPU power consumption = ~ 121 Watts

http://www.guru3d.com/article/radeon...ew-crossfire/9

Your psu should be rated @40 amps whichever way you decide, 5850 I would personally want a little more.
I run my 6850 with a 520w @ 40amp psu.

Maybe you didn't OC the CPU. He's running e6600 @3.0

EDIT: Still way too close to be comfortable

EDIT1: Not to mention capacitor aging- 450W PSU can't be new

is the cpu@3.0ghz gonna limit hd 6850 potential?
1. No*
2. No
3. Yes**

*Don't cheap out on a PSU. 450W is a stretch since PSU's (depending on their quality and age) don't actually deliver the power they put on the box.
** Crank up the graphix to the max in games and it probably won't bottleneck it as much, since lower FPS means less stress on the CPU and more on the GPU. But generally speaking I think it will bottleneck the card.

note that the max resolution that i will be able to play at is 1080p, other times at SXGA
and also im not planning on changing anything.. if the card is too good for this system im considering buying a weaker/cheaper one..

merry xmas.
450W will definitely not be enough for a 5850.

When upgrading, it's important to have a budget and balance out the upgrades. It's no use buying an enthusiast level part and combining it with low end parts, that will just bottleneck some parts and ... it's just a mess :-)

This. Although *maybe* 450W PSU could be able to run 5850. But it's a risk, yes.

the gpu is the most important for gaming.. i don't want to wast a total of +500$ just to to have no doubts it will have 100% available power at load and working at full potential that's why i ask.. so if anyone know or have the same specs.. and i might wait for the cheaper/lower juicy hd 6830..if 6850 is too good.

I have similar specs with a bit more demanding card (4870 has the exact same power consumption of 5850) and a bit better PSU. Still, nobody knows how much real juice comes from yours and how much from mine, but I'm running the 4870 (5850) problem-free (My CPU is 65W, yours is ~85 with the OC, I have 2 sticks of RAM, you have 1, 1 CD/DVD, 1 HDD, 1 PCIe, 1 extra fan for me)

As a final, there is a small risk in running the 6850 on your PSU. Worked for me, but I can't guarantee anything.
