Title: 3x5850 PSU Post by: no_alone on June 08, 2011, 05:56:23 PM What PSU should I use ??

Title: Re: 3x5850 PSU Post by: no_alone on June 08, 2011, 06:16:31 PM You think this could work?
ANTEC TRUEPOWER TRIO 650 WATT Title: Re: 3x5850 PSU Post by: no_alone on June 08, 2011, 06:40:39 PM A 650w PSU would barely support two. You need at least 850. Why? If the max power of one card is 150W then 3 cards is 450W thats 200 free for the system? Isnt it? Title: Re: 3x5850 PSU Post by: dudel42 on June 08, 2011, 06:46:22 PM I recently set up a triple 5850 system with a i7, 4gb ram, asus p55 board (I know it's a waste, but just had that around), and at full mining power I measure a total power consumption of ~560W.
I also bought an 850W PSU, just to be on the safe side, but from the figures (and with a more efficient mabo/cpu), I'd guess a 650-700 one would also suffice.

I'm also using 1 stick of 2gb core 2 due . Much less power Title: Re: 3x5850 PSU Post by: Freakin on June 08, 2011, 08:55:56 PM I recently set up a triple 5850 system with a i7, 4gb ram, asus p55 board (I know it's a waste, but just had that around), and at full mining power I measure a total power consumption of ~560W.
