Title: mining with multi 7950's Post by: katodumisani on May 29, 2013, 08:26:09 PM hi there, i'm new here, i plan to mine with 4 x 7950 radeon cards, two or three such sets. i know calculators already, my question is what is a 'real' power consumption? thx, kato.
Title: Re: mining with multi 7950's Post by: davidhanson on May 29, 2013, 08:40:00 PM Hello Kato,
I have such sets, 3x7950 and 4x7950 (gigabyte cards) with 'Gigabyte GA-990FXA-UD3 AM3' mainboard and on Chieftec bps-1200c power supply it's like 850-900W on 3 cards and 1000-1050W on 4 cards. Good luck, Dave Title: Re: mining with multi 7950's Post by: nordicbtcminers on May 29, 2013, 08:42:39 PM Hi Kato and welcome to the forum!
1 7950 takes app. 200-250W if i dont remember wrong 4 will then take app. 4 x 200W = 800W or 4 x 250 = 1000W I haved choosed a PSU with at least 1000W, i rec. 1200/1250 also check so there is enough Ampere och each rail and buy a psu that can handle SLI or QUAD GPU setups Title: Re: mining with multi 7950's Post by: katodumisani on May 29, 2013, 08:46:32 PM thanks dave! thanks nordicbtcminers!
is that dependent on processors and memories? is it constant consumption? kato Title: Re: mining with multi 7950's Post by: davidhanson on May 29, 2013, 08:50:01 PM Athlon x2 and 4 gb ram.
