Title: 2x7950 and a 1200W PSU - But how to connect them? Post by: ImI on April 09, 2013, 11:33:11 PM Hi there,
i have got two 7950s and a CoolerMaster1200W PSU. The 7950s have two 6-Pin entries and the leads from the PSU have 6-Pins and also another 6-Pin going out from those 6-Pin. (I hope its clear what i am trying to say.) Do i have to put two single 6-Pin leads on every GPU or just one and use this extra 6-Pin for the other entry of the GPU? Hope thats not to confusing, maybe i find a pic. Greets ImI Title: Re: 2x7950 and a 1200W PSU - But how to connect them?

(Of course using both 6-Pin leads of that cable) Yeah i know its an overkill. I am thinking of running 4x7950s. 5-6?? Really? I thought each 7950 needs 200W and 200W is as safety/mainboard etc. ?

Post by: btcminer021 on April 10, 2013, 01:53:37 PM Let me jump in and say I'm using three 7950s, each with 2x6 pin connectors, with an 850W Gold rated PSU. You're missing a few cards!
The cards should come with SATA or Molex to 6-pin PCIe converter cable, no? Title: Re: 2x7950 and a 1200W PSU - But how to connect them? Post by: middlemarkal on April 11, 2013, 10:46:20 PM litecoin need more power because it uses memory, but bitcoin uses no memory so you need less power.
IMO you never have to much power ;D |
