Title: Power Supply Post by: WaterTrooper on October 02, 2012, 06:54:21 AM I'm looking to build a basic Bitcoin miner. I will have a HDD and this is the power supply I'm look at. How many GPUs can it handle?

How much do you have to spend on cards? What CPU will you use? Have you considered running BAMT on a thumb drive/small SSD instead of using a mechanical hard drive that'll draw 50watts? If you're building a true mining rig (ie: single core CPU, 1 stick of RAM, SSD/flash storage) then you're perfectly safe running any of the following. Otherwise you're cutting it really, really close and may overdraw by just a little bit using the following options.
7970 x 4 (2500 MH/s @ ~ 860watts, ~$1600) or 6990 x 3 (2200 MH/s @ ~ 700watts, ~$hard to find, cost varies) or 5970 x 3 (roughly the same as 6990) or 5850 x 4 (1500 MH/s @ ~ 800watts, ~$550-600) Title: Re: Power Supply Post by: RaTTuS on October 02, 2012, 08:20:22 AM [edit]
