2 6950s on my PSU? - Page 2

post #11 of 44
Easier answer perhaps : No, your PSU is cheap/efficiency is low. You may have theoretically enough watts, but the efficiency of your PSU isn't good enough. Just don't risk.

I actually asked OCN and the general response was this is a good PSU. I guess its time for an upgrade though.




I won't run the second card on this PSU then, i dont want to risk it, what should i buy?

Click the link in my Signature. Our PSU editor posted a video and results with that card. I believe Rosewill are making decent PSU's but I would look into it.

Get a nice PSU from Corsair/Seasonic, 650-750w should be fine.

I don't see how bad their XFX PRO 650/750w is bad. It's bronze 80+, the price is lower, he isn't going to take all of the 750w with two 6950... But, fine, if you can find a better deal for corsair/antec/seasonic go for it.

My PSU is on the reccomended list http://www.overclock.net/power-suppl...-supplies.html

Also Phaedrus2129 tested Q9550 @ 3.7GHz + 6950 @ 940/1375, and got this

Max Values:
IBT : 230 Watts. -> 84% = 193.2W
Prime95 and Furmark : 370 Watts. -> 84% = 310.8W

so i dunno...

You should be ok. I've seen crossfire 6950 (w/20% powertune on each) + i7 920 @ 4.0ghz pull 580w at the wall. Don't expect to overclock with them though.

I would recommend a Seasonic or Corsair PSU. Check out the TX650, it's only $90 and it is a really good PSU for the price. Although for CF 6950's I think the TX750 is a better option.
