Power/Performance Conundrum

post #1 of 9
Thread Starter 
Ok, so here is my problem:

I want to buy 2 HD6950s and unlock them to 6970 potential in doing so I need to buy a new PSU that has more PCIe 6pin connectors or:

Buy 2 HD6950 directcu II cards for which my current PSU has the right amount of connectors. But I am not sure if 950w is enough to overclock them to 6970 potential and overclock my x6 Phenom to ~4.0ghz and all my other components and watercooling system.

Any thoughts or suggestions?

dude a 950W powersupply is more than enough for crossfire 6870s and and overclocked x6. You should be absolutely fine.

My concern is that these 6950s to overclock use this much power supposedly:

toyz72: No worries, this question is in regards to a brand new system I am building from the ground up in about a week or so.

Youre looking at 600w max draw in crossfire you should have plenty of power.

a 6950 only requires a 500w psu ....so theres no way one more card is going to use the other 450w.

Even with the cards overclocked and still leave enough power for an OC cpu and everything else? That is great to hear. I can save $140 by not buying a new PSU.
