The 403W figure was how much the PSU the OP was looking at had, not how much is needed.

That being said, while the Corsair CX 430 might do, I'd choose something else. I think it's more like a 380W PSU (although this might be one of the things the V2 improved upon), and while I can see a stock Phenom II and a Radeon 6850 working within that, I would personally choose something else over it though. It's not a bad option though.

I ran an 8800GT, an e7200 at 3.6Ghz with 1.45v, 3 LED fans, two ODD drives, two HDDs, and some cathodes all on a cheap ass 250w. The 12v, 5v, and 3v railing was perfectly stable at the time.
They say 500w to cover their ass with cheap PSUs.
buddy a CX430 gives out 510 watts at max according too THIS but y strain it and shorten its life but be on a safer side and go wtiha 530w PSU and thats not a cheap psu Rosewill learnt its lesson 4years ago and now makes pretty decent PSU thumb.gif

Pick one of these

They are from
Antec. I have used Eco Neo PSU's tons of time's in builds for myself and other people. For the money they are amazing PSU's. Never had one go out on me yet. Their rating is also continus rating. There is a website that push's the 620w Eco Neo to around 700w with no ill affects. I think the 500w would power your system just fine. the 620w I have can power both of my rigs with ease, I have even put a second 6970 with my sig rig and the eco neo. Worked fine.

I got a PC Power and Cooling PSU for $60 granted it's not modular but it does put out 760W with 62amps on the +12v rail. You should be a good PSU to cover yourself from straining your system pushing the PSU too far beyond what it can do. I'm not saying go get a 1000W one either, that's overkill for your rig as well but don't get too cheap either.

Edit: Thank you below for pointing out my number flaw.

Huh? The Silencer 760 should have a 62A +12V rail. Are you sure it's 46A? That's less than my Silencer 610 which has a 49A +12V rail.

Anyway, that's a very good PSU, especially for $60! It's a SeaSonic S12D.

check my sign for "How much power does your graphic card need" for more info on minimum requirement to the PSU
whats you budget budget??? 45$ extend it to 50 and go with Roswell Green series 530w PSu is the best in your budget though a bit out but yet redface.gif
hope that helps thumb.gif


No dude. Dude no. Yes bro. Bro yes. http://www.guru3d.com/article/radeon-hd-6850-6870-review/10 You are guys need to get your facts strait. AT FULL STRESS the ENTIRE SYSTEM WITH A 6850 USES 278w. And it has an overclocked i7 965. His cpu will not be OCED at and full stress it will only pull 95 watts and the 6850 will be 127 AT MAX. These numbers were pulled from the wall..... so factor in 80 percent from the psu and it will be roughly 222 watts. Quit recommending overkill power supplys even tho this is OCN thumb.gif If you want to spend the extra few bucks then the rosewill green series 530 is an excellent unit for the price. It will handle ANY single GPU out there.

Power consumption

Lets have a look at how much power draw we measure with this graphics card installed.

The methodology: We have a device constantly monitoring the power draw from the PC. We simply stress the GPU, not the processor. The before and after wattage will tell us roughly how much power a graphics card is consuming under load.

Our test system is based on a power hungry Core i7 965 / X58 based. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.

Keep that in mind. Our normal system power consumption is higher than your average system.

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
Measured power consumption - 6870

Advertised TDP = 150W
System in IDLE = 173W
System Wattage with GPU in FULL Stress = 295W
Difference (GPU load) = 122 W
Add average IDLE wattage ~ 19W
Subjective measured GPU power consumption = ~ 141 Watts
Bear in mind that the system Wattage is measured from the wall socket and is for the entire PC. Below, a chart of measured Wattages per card. Overall this is much higher than reference, this is due to an increased GPU voltage to allow easy overclocking and the standard higher clock frequencies.

Like I said, A 620w will hold my entire sig rig with overclocks and a second 6970 with room to spare.

Over at Neweegg I found a OCZ ModXStream Pro 700W modular PSU going for $90, $10 instant and $30 after MIR, making total cost $60.

No.

His PSU should have been fine. Something else went wrong.
