Title: 6950 & 7950 Power Supply Post by: buildbit on April 07, 2013, 11:04:03 AM Hi Guys,
Im just getting into mining and i want to make sure I dont kill my pc. My specs are as follows: PSU: Coolermaster GX 750W Bronze Motherboard: MSI Z77A-G41 CPU: Intel i5 3300 (something like that) Graphics: MSI Twin Frozer 7950 & Powercolor 6950. I was just wanting to know if the power supply i have will be sufficient for the two cards under full load. Any advice would be appreciated. Thanks Title: Re: 6950 & 7950 Power Supply Post by: cdog on April 07, 2013, 11:48:12 AM yes

I've actually got another 7950 now, do you think the psu will handle a third card? Title: Re: 6950 & 7950 Power Supply Post by: induktor on April 28, 2013, 01:22:16 PM No, three of those cards are too much for your PSU
I've tested 2 x 7950 here at full load in BTC they eat 520W at the power socket with the coolermaster GX 650, adding a 6950 will pretty damn sure be around 670W , maybe more, even if the psu can handle 100% load, it is not recommended to use more than 70% or 80% of the psu capacity, you will kill it in very short time, and the coolermaster are excellent units, it would be a pity to loose it. Just get rid of the 6950, or put it in another machine. (7000 series are FAR more efficient MH per W) EDIT: my numbers are based in a machine with sempron 145 processor, you have i5, so, add 40W more to my numbers.
