And go look at the sticker on that CoolMax unit. It's a REALLY old design, considering it has a lot of power on the 5v and 3.3v rails. And its only rated for 420w PEAK on the 12v rails. The 6950 will easily pull 250w on its own, if not more after an overclock. If that PSU can only produce 250w continuous, it WILL pop.
From what I saw on guru3d, the card pulls 158W http://www.guru3d.com/article/radeon...6970-review/11

That Coolmax 600W is really more like a 450W power supply. I would not overclock the 6950 at all on it. It is already shaky as it at stock.

I would not put much faith in the reliability of this PSU. It may work now, but who knows when it might fail in the future.

All the Coolmax PSU reviews on JonnyGuru.com had pretty bad scores.

250W on its own? Really?

Not according to what I found. Here's one source:

http://www.guru3d.com/article/radeon...6970-review/11

Keep in mind, all values are measured at the wall.

Then they find the difference to approximate just how much power the card is pulling on its own, and it's far less than 250W. Not even the GTX 470 can pull more than 215W from a power supply at stock.

Akali: do you want to overclock the card at all?


Edit: lol we posted the same article.

Edit 2: Oh and once again: Your power supply is enough.

measured power consumption radeon hd 6950
  1. system in idle = 174w
  2. system wattage with gpu in full stress = 312w
  3. difference (gpu load) = 138w
  4. add average idle wattage ~ 20w
  5. subjective obtained gpu power consumption = ~ 158 watts
I see 312 watts at load.

Here, I'll tell you what TwoCables. If you're SOOO confident on that CoolMax PSU, I'll buy you one. Nvidia says 550w for your GTX 465, as seen here. I will BUY YOU a CoolMax 600w PSU, but you have to run it for a year on your system (or until you upgrade to something that needs more power).

What is that? You're not comfortable running your $300 graphics card on a $20 PSU? Yeah, I don't blame you. So why are you recommending him do it?

Akali:
Would you SERIOUSLY trust a $300 graphics card, to a $20 PSU? I know I wouldn't. This would be absolutely NO different than using a 600w RaidMax or 600w Diablotek unit.

Maybe a little overclock but I don't mind to let it run on stock

That's at the wall. That's why they said "System" wattage. "System wattage" means that's what the power draw is at the wall.

Now, take a look at the difference that they are approximating.

Which exact Coolmax power supply do you have?

pioneerisloud: this has not yet been established.

Again, do you REALLY want to trust a $300 graphics card to a $20 PSU? Especially one that is KNOWN for bad failure rates because of it being such a horrible unit?

Whatever, do what you want. It's your money. You might as well light that $300 on fire though, because that's what will end up happening.

Where do you see that it's a $20 power supply? We don't even know exactly which unit he has yet! Why are you so sure?! The one you asked him about way earlier is a $70 600W unit! And it's not even that horrible of a PSU either!!!

Good GRIEF!
